FIRST\u003c\/h2\u003e\n\u003cp\u003eAres Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFREE \u0026amp; FAST Shipping is included for all U.S. customers.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWe understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.\u003c\/p\u003e\n\u003cp\u003eFor a commercial T50 operator, a generator that starts but cannot produce stable charging output is still a failed generator. Ares Acres builds its generator catalog around component-level repair so operators and service technicians can isolate the failed section of the charging system instead of replacing the entire charging station whenever a board or power module fails.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWe use specialized technicians to verify and dispatch the D12000iEP Generator DC Power Controller Module ordered.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eParts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.\u003c\/p\u003e\n\u003cp\u003eThat is why Ares Acres keeps hard-to-find OEM generator parts in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.\u003c\/p\u003e\n\u003cp\u003eFor professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T50, this is the part that keeps a scheduled job on the calendar instead of on hold.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e✅ Compatibility\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDJI Agras T50 charging workflows\u003c\/li\u003e\n\u003cli\u003eD12000iEP generator family\u003c\/li\u003e\n\u003cli\u003eCompatible D12000-series charging-station configurations using the same DC power module architecture\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFitment must be confirmed before purchase.\u003c\/strong\u003e Compare the original module’s connector layout, board shape, heat-sink arrangement, harness exits, mounting locations, generator designation, controller label, and electrical interfaces. Do not assume D12000i, D12000iE, and D12000iEP power modules are interchangeable solely because the generator housings appear similar.\u003c\/p\u003e\u003ch2\u003e📦 Package Includes\u003c\/h2\u003e\u003cp\u003eOne DC power controller module in the supplier-listed configuration.

The DC controller module forms part of the power-conditioning stage that rectifies, filters, switches, regulates, monitors, and controls high-power electrical energy before it is delivered to the charging system.\u003c\/p\u003e\u003cp\u003eLarge capacitors help stabilize the DC bus. Inductors and transformers manage current and switching behavior. Heat sinks draw heat away from power semiconductors. Control circuitry monitors voltage, current, temperature, and fault conditions. Together these components allow the generator to provide controlled energy rather than unregulated alternator output.\u003c\/p\u003e\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConverts and regulates generator electrical output.\u003c\/li\u003e\n\u003cli\u003eSupports stable high-current DC power delivery.\u003c\/li\u003e\n\u003cli\u003eFilters electrical ripple and transient conditions.\u003c\/li\u003e\n\u003cli\u003eControls power switching under battery-charging load.\u003c\/li\u003e\n\u003cli\u003eInterfaces with generator control and protection logic.\u003c\/li\u003e\n\u003cli\u003eSupports over-voltage, over-current, thermal, or other protective shutdown behavior depending on generator firmware and architecture.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWork the removal in a deliberate order rather than by whichever fastener is easiest to reach. Shut down, isolate the generator battery, disconnect the charging leads at the aircraft-battery end first so the cables are dead before they are handled, and then wait out the capacitor discharge step the service procedure calls for. Release the signal connectors, then the high-current terminals, and take out the module's chassis fasteners last, so the assembly stays supported on its mounts while its heavy connections are being freed.\u003c\/p\u003e\n\u003cp\u003eThe thermal interface is the part of the refit most often done badly and the part that most often kills a replacement early. Whatever sits between the power semiconductors, their heat sinks, and the chassis is there to fill microscopic surface roughness, not to bridge a real gap. Clean every trace of old pad or compound off both faces, check the mating surface for burrs and raised edges left by a previous repair, fit fresh interface material rather than reusing something that has already been compressed, and keep fingers off the contact faces.\u003c\/p\u003e\n\u003cp\u003eHigh-current terminals are where a careful refit is either made or lost. Start every nut or bolt by hand so a cross-thread is felt before a wrench can hide it, rebuild each washer stack exactly as it came apart, and bring the hardware up evenly across all terminals instead of pulling one fully home before starting the next. Do not pack a joint with grease in the belief that it prevents corrosion. A film between two current-carrying faces raises contact resistance, and resistance at a high-current joint turns straight into heat.\u003c\/p\u003e\n\u003cp\u003eThe first question to settle is whether the generator is failing to make power or failing to convert it, and the engine will tell you if you listen. Command a charge with the engine warm and running. If it holds its light no-load note and never loads up, no current is being drawn through the conversion stage at all, which points at this module, its command path, or the output side rather than at the engine. If the engine pulls down hard and then the unit trips, current was flowing and the fault sits on the load side or in the module's own protection.\u003c\/p\u003e\n\u003cp\u003eSeparate this module from the two assemblies most often confused with it before ordering anything. The DC power controller carries the heavy end of the job, so it is built around stud or busbar terminals, bulky electrolytic capacitors, wound inductors, and semiconductors clamped to substantial finned or plate heat sinks. A generator control board looks nothing like it once the two are side by side, being mostly thin signal connectors and small logic parts with no meaningful heat sinking. The engine ECU sits close to the engine and its harness runs to injection, ignition, and throttle rather than to charging output.\u003c\/p\u003e\n\u003cp\u003eRecord the installation before a single fastener moves. Photograph the harness routing and every cable tie point, note which terminal each ring lug or busbar came off and the stack order of the washers and hardware on that stud, and mark the module against the chassis with a paint pen so orientation is never a matter of memory during refit. A high-current terminal rebuilt with the washer stack in the wrong order is a hot joint waiting to happen, and it will look completely normal in a photograph taken afterwards.\u003c\/p\u003e\n\u003ch2\u003e⚠️ Common Failure Symptoms\u003c\/h2\u003e\u003cp\u003ePossible DC-controller-related symptoms can include an engine that runs normally but produces no usable charging output, immediate charging shutdown under load, repeated power-stage fault codes, unstable output voltage, visible burned components, swollen or leaking capacitors, cracked solder joints, heat-damaged connectors, abnormal electrical odor, or a module that has suffered moisture or contamination damage.\u003c\/p\u003e\u003cp\u003eThese symptoms are not exclusive to the DC module. Before replacement, inspect the stator, rotor, generator controller, ECU, output cable, battery interface, communication harness, temperature sensors, cooling fans, control panel, grounding, and all high-current connectors.\u003c\/p\u003e\u003ch2\u003e🧪 Diagnostic Guidance\u003c\/h2\u003e\u003cp\u003eHigh-power generator diagnostics should be performed by qualified personnel using appropriate insulated tools and test equipment. Depending on the failure, diagnosis may involve visual inspection, connector continuity, insulation checks, phase-output comparison, DC-bus measurements, fault-code review, thermal inspection, and comparison against a known-good module.\u003c\/p\u003e\u003cp\u003eDo not probe energized high-voltage sections casually. Large capacitors may retain energy after shutdown. Follow the applicable service procedure and allow the system to discharge before handling internal power electronics.\u003c\/p\u003e\u003ch2\u003e🌡️ Cooling \u0026amp; Thermal Management\u003c\/h2\u003e\u003cp\u003ePower electronics generate substantial heat during battery charging. Inspect cooling fans, ducts, heat sinks, thermal pads, mounting surfaces, and air passages whenever this module is serviced. Replacing a damaged controller without correcting a failed cooling fan or blocked airflow can cause the replacement module to fail again.\u003c\/p\u003e\u003ch2\u003e📐 Product Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct:\u003c\/strong\u003e Generator DC power controller module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenerator:\u003c\/strong\u003e D12000iEP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAircraft workflow:\u003c\/strong\u003e DJI Agras T50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem:\u003c\/strong\u003e Power conversion \/ charging electronics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New replacement component\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation level:\u003c\/strong\u003e Advanced generator electrical repair\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eStored Energy:\u003c\/strong\u003e The DC bus can hold a dangerous charge long after shutdown; follow the discharge step in the service procedure and confirm with a meter before touching internal power sections\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThermal Interface:\u003c\/strong\u003e Replace pads or compound rather than reusing compressed material, and clean both mating faces back to bare metal before fitting\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTerminal Hardware:\u003c\/strong\u003e Rebuild each washer stack in its original order, start every fastener by hand, and keep grease off the current-carrying faces\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePublished Electrical Ratings:\u003c\/strong\u003e Voltage, current, and component values for this module are not published in the material behind this listing; match the label, connector layout, and terminal arrangement on the module you removed\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eESD Handling:\u003c\/strong\u003e Leave the module in its antistatic packaging until the moment it goes in, and ground yourself before handling connectors or exposed board areas\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStorage:\u003c\/strong\u003e Store indoors, dry, and at moderate temperature; electrolytic capacitors degrade during long unpowered storage, and heat accelerates it\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFault Log:\u003c\/strong\u003e Read and write down the stored codes before clearing anything; a log cleared early destroys the best evidence you have of what actually failed\u003c\/p\u003e\n\u003ch2\u003e🧰 Installation Guidance\u003c\/h2\u003e\u003cp\u003eDisconnect the generator battery and all charging leads before service.

A healthy engine paired with a failed controller cannot keep a battery rotation moving. Component-level access to this module can therefore convert a nonproductive generator into a repairable asset rather than a total replacement.\u003c\/p\u003e\u003cp\u003eHandling before installation matters more than most operators expect. A power module is heavy for its size and the mass is concentrated in the capacitors and the wound components, so a drop on one corner can crack a solder joint or fracture a component lead without leaving a mark anyone would notice. Keep it in its packaging until it is going in, carry it by the chassis rather than by a heat sink or a harness, and never let it hang on its own cables while a mounting fastener is being started.\u003c\/p\u003e\n\u003cp\u003eThis is not a part to change on a calendar. Replacing it preventively only makes sense when the evidence is already in front of you: capacitors starting to dome, discoloration around a terminal, a fault that comes back every time the unit gets hot, or a documented history of water in the enclosure. The separate argument is inventory rather than condition. An operator running a single charging generator through a short window has good reason to keep one on the shelf, because the module costs very little next to a fleet standing still.\u003c\/p\u003e\n\u003cp\u003eWhat shortens the life of this module is almost always heat and vibration rather than hours of use on their own. A charging generator lives on a trailer or a truck bed, gets hauled over rough ground between fields, and then runs at high output in summer heat with dust and chaff in the air. Every one of those conditions works on the same handful of things: the mounting of the heavy capacitors and magnetics, the solder joints underneath them, the clamping force at the heat sink, and the tightness of the high-current terminals.\u003c\/p\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eCanonical name:\u003c\/strong\u003e DJI Agras D12000iEP Generator DC Power Controller Module\u003cbr\u003e\u003cstrong\u003eAircraft:\u003c\/strong\u003e DJI Agras T50\u003cbr\u003e\u003cstrong\u003eGenerator:\u003c\/strong\u003e D12000iEP\u003cbr\u003e\u003cstrong\u003eComponent type:\u003c\/strong\u003e DC power electronics \/ converter\/controller module\u003cbr\u003e\u003cstrong\u003ePrimary function:\u003c\/strong\u003e High-power electrical conversion and regulation\u003cbr\u003e\u003cstrong\u003eCategory:\u003c\/strong\u003e Generator Parts\u003cbr\u003e\u003cstrong\u003eAlso searched as:\u003c\/strong\u003e D12000iEP DC module, T50 generator DC board, DJI generator power board, T50 charging station controller, D12000 power controller, DJI Agras generator inverter board.\u003c\/p\u003e\u003ch2\u003e🔍 SEO Keywords\u003c\/h2\u003e\n\u003cp\u003eDJI Agras T50\u003c\/p\u003e\n\u003cp\u003eDJI Agras T50 Parts\u003c\/p\u003e\n\u003cp\u003eDJI T50 Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras T50 OEM Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras T50 replacement parts\u003c\/p\u003e\n\u003cp\u003eAgras T50 parts USA\u003c\/p\u003e\n\u003cp\u003eDJI Agras D12000iEP Generator DC Power Controller Module\u003c\/p\u003e\n\u003cp\u003eD12000iEP Generator DC Power Controller Module OEM\u003c\/p\u003e\n\u003cp\u003ed12000iep generator dc power controller module replacement\u003c\/p\u003e\n\u003cp\u003ed12000iep generator dc power controller module for sale\u003c\/p\u003e\n\u003cp\u003eDJI D12000iEP Generator DC Power Controller Module\u003c\/p\u003e\n\u003cp\u003eT50 D12000iEP Generator DC Power Controller Module\u003c\/p\u003e\n\u003cp\u003eDJI T50 D12000iEP Generator DC Power Controller Module\u003c\/p\u003e\n\u003cp\u003eDJI Agras T50 D12000iEP Generator DC Power Controller Module OEM\u003c\/p\u003e\n\u003cp\u003eGenerator Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras Generator Parts\u003c\/p\u003e\n\u003cp\u003eT50 Generator Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras OEM Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras Replacement Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras Repair Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras Maintenance Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agricultural Drone Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agriculture Drone Parts\u003c\/p\u003e\n\u003cp\u003eDJI Spray Drone Parts\u003c\/p\u003e\n\u003cp\u003eDJI Crop Sprayer Parts\u003c\/p\u003e\n\u003cp\u003eagricultural drone parts\u003c\/p\u003e\n\u003cp\u003espray drone parts\u003c\/p\u003e\n\u003cp\u003eag drone parts USA\u003c\/p\u003e\n\u003cp\u003eplant protection drone parts\u003c\/p\u003e\n\u003cp\u003eauthorized DJI Agras reseller\u003c\/p\u003e\n\u003cp\u003eDJI Agras dealer USA\u003c\/p\u003e\n\u003cp\u003ebuy DJI Agras parts online\u003c\/p\u003e\n\u003cp\u003eDJI Agras parts free shipping\u003c\/p\u003e\n\u003cp\u003eagricultural drone parts same day shipping\u003c\/p\u003e\n\u003cp\u003eAres Acres\u003c\/p\u003e\n\u003cp\u003eAres Acres LLC\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🚚 Shipping, Returns \u0026amp; Support\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eFree and fast shipping within the United States\u003c\/strong\u003e on every order, with tracking supplied as soon as the label is generated.

How do I tell the DC module from the stator or the wiring?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWatch what the engine does when a charge is commanded. If it stays at its light no-load note and never pulls down, no current is being drawn and the fault is on the conversion or command side rather than in the engine. From there, confirm the output cable and battery interface are sound, read the stored fault codes, and inspect the module for domed capacitors, scorch marks, or a cooked terminal. A stator fault normally shows as an output imbalance or an insulation failure, not as complete silence.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long do I have to wait before it is safe to touch the inside of the generator?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLong enough for the DC bus to discharge, and then confirm it with a meter rather than a stopwatch. Bulk capacitors on a power module can hold a dangerous charge well after the engine has stopped and every indicator has gone dark, and a bleed resistor that has failed open will leave them charged indefinitely. Follow the discharge step in the service procedure, measure across the bus terminals before working, and treat the module as live until the meter says otherwise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I just replace the swollen capacitors instead of the whole module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOn a bench with the right equipment that is sometimes possible, but a domed capacitor is a symptom more often than a root cause. Capacitors dome because they have been run hot, and whatever ran them hot, whether a failed fan, a blocked fin stack, a degraded thermal interface, or a switching device that is already leaking, is still present after they are changed. If the module is being repaired rather than replaced, the heat path and the semiconductors have to be assessed at the same time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs a burn mark around one terminal a module failure or a wiring failure?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eScorching that radiates from a single terminal and stops there is a joint problem rather than a board problem. A loose lug, a washer stack rebuilt in the wrong order, corrosion between the faces, or grease left between two current-carrying surfaces all raise resistance at that one point, and the heat appears exactly where the resistance is. Inspect the cable lug and the stud as well as the module, because a terminal hot enough to discolor a board has usually ruined the lug too.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill a replacement module fix a generator that keeps overheating?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNot on its own. If the unit charges normally and then drops out as it warms, the module is the victim of a heat problem rather than the source of it. Before the replacement goes in, check that the cooling fans spin freely and come on when they should, that the fin stack and inlet screens are not packed with dust and chaff, that the exhaust path is clear, and that the heat-sink mounting is tight with intact interface material. Fitting a new module into the same conditions only buys a short reprieve.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I tell this module apart from the generator control board on the bench?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBy what it is built to carry. The DC power controller has heavy terminals or busbars, bulky electrolytic capacitors, wound inductors or transformers, and semiconductors clamped to substantial heat sinks. A control board is mostly thin signal connectors, small logic components, and no meaningful heat sinking. If the assembly in your hand has a harness heavy enough to carry charging current, it is the power module. If every wire leaving it is signal-sized, it is something else.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the module come out before or after the high-current cables?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCables first, module last. Free the signal connectors, then the high-current terminals, and only then release the chassis fasteners, so the assembly stays supported on its mounts while its heavy connections are being broken. Taking the mounting fasteners out first leaves the full weight of the module hanging on its own terminals and harness, which is how lugs get bent, studs get sheared, and a board gets cracked at a mounting boss on the way out.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe old thermal pad looks intact. Can I reuse it?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. A pad that has spent its life under clamping pressure has taken a permanent set and will not fill the surface roughness the same way a second time, and once peeled it usually tears or picks up grit. Take all the old material off both faces, check the mating surface for burrs or high spots left by a previous repair, and fit fresh interface material. A compromised heat path is the single most common reason a replacement power module fails early.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I clear the fault codes before or after I change the module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRead them and write them down first, then leave the log alone until the new module is in and the machine has been run. That stored history is the best evidence available of what actually failed and whether the same code has been recurring quietly for weeks, and clearing it early throws it away. After the repair, clear the log deliberately so anything that appears afterwards is known to be new rather than left over from the failure you have just fixed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat should I check on the first run after fitting it?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTerminal temperature is the check most people skip. After a short run under charging load, shut down, isolate, and feel or measure each high-current joint. One connection noticeably warmer than the rest means that joint is not making proper contact and needs to come apart and be rebuilt before it cooks itself. Alongside that, confirm the fans are running, air is actually moving through the fin stack, and no new codes have appeared in the log.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe generator stood all winter and now will not charge. Where do I start?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eStart with what standing does rather than assuming a failed part. Damp works its way into an enclosure that has cooled and warmed for months, so look for tide lines, corrosion, and rodent damage in the harness before condemning anything. Electrolytic capacitors also degrade during long unpowered storage, so check for doming and dried residue. Check the fuel and starting-battery side too, because weak cranking can produce charging faults that have nothing to do with this module.\u003c\/p\u003e\n\u003chr\u003e","brand":"DJI","offers":[{"title":"D12000iEP","offer_id":53027325215040,"sku":null,"price":1299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/0159\/0848\/files\/IMG-8137.png?v=1787749058","url":"https:\/\/aresacres.com\/products\/dji-agras-t50-oem-d12000iep-generator-dc-power-controller-module","provider":"Ares Acres","version":"1.0","type":"link"}
