This assembly handles the AC-side power-conversion stage that supplies controlled electrical power into the charging system and is intended for service of charging stations or charger assemblies that have confirmed internal power-electronics failure.\u003c\/p\u003e\u003ch2\u003e🇺🇸 U.S.A. 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\u003eAres Acres LLC supplies field-charging and generator components for DJI Agras operators who depend on continuous battery rotation. In agricultural-drone operations, a charger failure can stop an otherwise healthy fleet because batteries cannot return to service quickly enough. Component-level charging-system repair can therefore protect both hardware investment and application uptime.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWe use specialized technicians to verify and dispatch the Charger AC Power Module \/ Charging Station AC 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.

Before ordering, compare enclosure shape, capacitor and inductor layout, connector arrangement, mounting points, harness configuration, input\/output topology, and the original charger or station model. Do not assume interchangeability with C10000, D12000-series generator DC controllers, inverter boards, or other charger power modules solely because they appear similar.\u003c\/p\u003e\u003ch2\u003e📦 Package Includes\u003c\/h2\u003e\u003cp\u003eOne charger AC power module in the supplier-listed configuration. External charger enclosure, generator, cooling fans, wiring harnesses, battery cable, control\/display panel, fasteners, and other power modules are not assumed included unless specifically supplied with the final part.\u003c\/p\u003e\u003ch2\u003e⚡ Component Overview\u003c\/h2\u003e\u003cp\u003eThe AC module is part of the charger’s high-power conversion path. In broad terms, AC input power must be conditioned, switched, filtered, and converted into a form the charging system can regulate for the battery. The module contains high-current and high-voltage electronic components such as capacitors, inductors, semiconductor switching devices, relays, filters, and control interfaces.\u003c\/p\u003e\u003cp\u003eBecause these components operate under electrical and thermal stress, failure can occur after surges, overheating, cooling loss, contamination, connector damage, internal short circuits, or prolonged high-load operation. A failed AC module can prevent charger startup, trip protection, create unstable output, or cause the charger to stop under load.\u003c\/p\u003e\u003cp\u003eProve the supply before condemning the module, and prove it under load rather than at rest. A meter on an idle outlet or a resting generator will read perfectly normal and still be hiding the problem. Measure at the charger inlet while the unit is actually trying to draw current, and compare what you see against the input rating printed on the charger label. A long or undersized extension cord, a worn plug, a tired generator, or a shared circuit will all sag under load and look exactly like a dead power module.\u003c\/p\u003e\n\u003cp\u003eThe substitution ladder saves more chargers than test equipment does, provided you change one thing at a time. Start with the input cord, then the outlet or generator receptacle, then the battery, then the battery cable, and note what changes at each step. If a second charger runs on the same cord and the same receptacle, the supply is cleared and the fault is inside the unit. If neither charger will run on that supply, you have found a source problem and a replacement module would have changed nothing.\u003c\/p\u003e\n\u003cp\u003eWhat the charger does in the first second after it is energized narrows the fault faster than anything else. A unit that stays completely dark and silent with live input confirmed at the inlet has a problem in the input path: the inlet itself, a fuse or breaker, the input filter, the inrush limiting, or the AC stage. A unit that wakes up, lights its display, and spins its fans has an auxiliary supply that is working, and a fault that only appears once charging begins has moved downstream of the AC input.\u003c\/p\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReceives and conditions AC-side input power.\u003c\/li\u003e\n\u003cli\u003eSupports conversion of incoming power for the charger’s regulated output stages.\u003c\/li\u003e\n\u003cli\u003eFilters electrical noise and stabilizes the high-power conversion path.\u003c\/li\u003e\n\u003cli\u003eInterfaces with charger control electronics and protection circuitry.\u003c\/li\u003e\n\u003cli\u003eSupports reliable battery charging under sustained field load.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eOpening a charger enclosure is not the same as opening a flight-battery bay, and the difference is the mains side. Isolate at the source and pull the plug rather than trusting a switch, wait out the discharge, and verify with a meter across the bulk capacitors before a hand goes inside. Note the length of every fastener as it comes out. Enclosure screws on charging equipment are frequently mixed lengths, and a long screw driven into a shallow boss can reach a board, a conductor, or a harness behind it.\u003c\/p\u003e\n\u003cp\u003eThe protective earth connection is the one wire that must never be treated casually. On mains-powered equipment the bonding strap between the enclosure, the chassis, and the incoming ground is a safety device rather than a convenience. It comes off last during disassembly and goes back on first during reassembly, with its original serrated or star hardware, onto clean bare metal. A ground reconnected onto paint, or left dangling because it was in the way, turns a future insulation failure into a shock hazard.\u003c\/p\u003e\n\u003cp\u003ePut the insulation back the way the factory had it. Mains-side assemblies rely on physical spacing, insulating barriers, sleeving, cable clamps, and routing that deliberately keeps input wiring away from low-voltage wiring, and every one of those details is doing a job. Do not reroute the input leads to make the inside look tidier, do not leave out a barrier that seems to be in the way, and restore each clamp and strain relief. Loose mains wiring inside a charger that lives on a trailer finds a sharp edge eventually.\u003c\/p\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\u003cp\u003ePotential indicators include a charger that will not power up after input power has been verified, repeated protection shutdown, visible board damage, burned or swollen components, evidence of overheating, internal arcing, damaged high-current connectors, a confirmed short or open circuit on the AC conversion board, or diagnostic results pointing specifically to the AC power stage.\u003c\/p\u003e\u003cp\u003eDo not replace the module solely because a battery fails to charge. Charging problems can also originate from the battery, charging cable, connector, generator output, input supply, control board, cooling system, sensors, communications, or another power module.\u003c\/p\u003e\u003cp\u003eCharger completely dark with live power confirmed at the inlet under load, which puts the fault in the input path rather than in the output stage\u003c\/p\u003e\n\u003cp\u003eBreaker or fuse letting go at the instant the charger is plugged in, before any battery is connected, which points at inrush limiting or a shorted input component\u003c\/p\u003e\n\u003cp\u003eCharger powering up and displaying normally but shutting down the moment a battery is connected, which moves suspicion downstream of the AC stage\u003c\/p\u003e\n\u003cp\u003eRapid clicking or chattering from inside the enclosure at power-up, which is a relay unable to hold in and is often a sagging supply rather than a failed board\u003c\/p\u003e\n\u003cp\u003eCharging that works on a wall outlet at the shop and fails on the generator in the field, which is a supply-quality problem until proven otherwise\u003c\/p\u003e\n\u003cp\u003eA sharp acrid smell with nothing visible from above, which usually means something vented or a coating scorched on a surface you cannot see from the top of the board\u003c\/p\u003e\n\u003cp\u003eBrown heat shadow baked into the enclosure wall or the board around one component, showing exactly where the energy has been going\u003c\/p\u003e\n\u003cp\u003eDark tracking marks or fine carbon lines running between adjacent conductors or across a connector, which is arcing driven by damp and dust rather than by a failed part\u003c\/p\u003e\n\u003cp\u003eFans that run but move very little air because the intake screen is felted with dust and crop residue, which cooks a power module quietly over weeks\u003c\/p\u003e\n\u003cp\u003eCorrosion, dew staining, or insect nesting inside an enclosure that has been left outdoors on a trailer between jobs\u003c\/p\u003e\n\u003ch2\u003e🔍 Diagnostic Checklist\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify input power and source voltage are correct for the charger.\u003c\/li\u003e\n\u003cli\u003eInspect external power cables and connectors for heat damage or looseness.\u003c\/li\u003e\n\u003cli\u003eCheck cooling fans and airflow before condemning a power module.\u003c\/li\u003e\n\u003cli\u003eInspect the board for burned areas, cracked components, bulged capacitors, or discoloration.\u003c\/li\u003e\n\u003cli\u003eCheck fuses and protection devices where applicable.\u003c\/li\u003e\n\u003cli\u003eVerify battery and charging cable functionality with known-good components if possible.\u003c\/li\u003e\n\u003cli\u003eDistinguish AC power-stage failure from DC output-stage, controller, or communication faults.\u003c\/li\u003e\n\u003cli\u003eConfirm exact module geometry and connectors against the removed part.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e🧰 Installation \u0026amp; Safety Considerations\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eHigh voltage warning:\u003c\/strong\u003e charging-system power electronics can retain dangerous electrical energy after power is disconnected.

During high-tempo application, the charger is effectively part of the aircraft’s productivity system. If charging throughput collapses, the fleet becomes battery-constrained even when every aircraft is mechanically healthy.\u003c\/p\u003e\u003cp\u003eReplacing the failed internal power module may preserve the charger enclosure, cooling system, control electronics, cables, and other expensive assemblies. For commercial operators, restoring a charger at board\/module level can materially reduce downtime and replacement cost.\u003c\/p\u003e\u003cp\u003eField charging equipment leads a harder life than the same electronics would indoors, and that is what really sets the service life of this module. It is hauled on a trailer, sits in the sun with heat soaking into the enclosure, breathes dust and spray drift through its cooling path, and cools every night into condensation. Dust plus overnight damp is the combination that produces tracking and corrosion on mains-side conductors, and it works slowly enough that nothing looks wrong until the morning the charger will not start.\u003c\/p\u003e\n\u003cp\u003eSupply quality does as much long-term damage as any of that. Undersized extension cords, worn receptacles, and generators run close to their limit all present a sagging or unstable input, and a converter asked to hold its output on a weak input simply draws more current, which turns into heat in exactly the components that later fail.

Leave it sealed in its antistatic bag until the enclosure is open, clean, and ready to receive it, keep it off a concrete floor where condensation collects, and let a module that has been stored cold come up to shop temperature before unwrapping so moisture does not condense on it. Carry it by the frame rather than by a heat sink or a connector, and do not stack anything on top; the tall components break their own solder joints.\u003c\/p\u003e\n\u003ch2\u003e🔄 Adjacent Components to Inspect\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eInput power cable and terminals\u003c\/li\u003e\n\u003cli\u003eCooling fans and airflow channels\u003c\/li\u003e\n\u003cli\u003eDC power module \/ output stage\u003c\/li\u003e\n\u003cli\u003eControl board\u003c\/li\u003e\n\u003cli\u003eCharging cable and battery connector\u003c\/li\u003e\n\u003cli\u003eTemperature sensors\u003c\/li\u003e\n\u003cli\u003eFuses and protection devices\u003c\/li\u003e\n\u003cli\u003eThermal pads and heat sinks\u003c\/li\u003e\n\u003cli\u003eGenerator or utility input source\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eCanonical product name:\u003c\/strong\u003e DJI Agras T40 Charger AC Power Module\u003cbr\u003e\u003cstrong\u003eAircraft ecosystem:\u003c\/strong\u003e DJI Agras T40\u003cbr\u003e\u003cstrong\u003eComponent:\u003c\/strong\u003e Internal charger AC-side power electronics module\u003cbr\u003e\u003cstrong\u003eSystem:\u003c\/strong\u003e Batteries and charging \/ field charging infrastructure\u003cbr\u003e\u003cstrong\u003ePrimary function:\u003c\/strong\u003e High-power AC conditioning and conversion\u003cbr\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e New\u003cbr\u003e\u003cstrong\u003eProduct category:\u003c\/strong\u003e Batteries \u0026amp; Charging\u003cbr\u003e\u003cstrong\u003eSeller:\u003c\/strong\u003e Ares Acres LLC\u003cbr\u003e\u003cstrong\u003eAlso searched as:\u003c\/strong\u003e T40 charger AC board, DJI Agras T40 charging module, T40 charger power board, Agras AC module, T40 charging station power module\u003c\/p\u003e\u003ch2\u003e🔍 SEO Keywords\u003c\/h2\u003e\n\u003cp\u003eDJI Agras T40\u003c\/p\u003e\n\u003cp\u003eDJI Agras T40 Parts\u003c\/p\u003e\n\u003cp\u003eDJI T40 Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras T40 OEM Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras T40 replacement parts\u003c\/p\u003e\n\u003cp\u003eAgras T40 parts USA\u003c\/p\u003e\n\u003cp\u003eDJI Agras Charger AC Power Module \/ Charging Station AC Module\u003c\/p\u003e\n\u003cp\u003eCharger AC Power Module \/ Charging Station AC Module OEM\u003c\/p\u003e\n\u003cp\u003echarger ac power module \/ charging station ac module replacement\u003c\/p\u003e\n\u003cp\u003echarger ac power module \/ charging station ac module for sale\u003c\/p\u003e\n\u003cp\u003eDJI Charger AC Power Module \/ Charging Station AC Module\u003c\/p\u003e\n\u003cp\u003eT40 Charger AC Power Module \/ Charging Station AC Module\u003c\/p\u003e\n\u003cp\u003eDJI T40 Charger AC Power Module \/ Charging Station AC Module\u003c\/p\u003e\n\u003cp\u003eDJI Agras T40 Charger AC Power Module \/ Charging Station AC Module OEM\u003c\/p\u003e\n\u003cp\u003eBatteries \u0026amp; Charging\u003c\/p\u003e\n\u003cp\u003eDJI Agras Batteries \u0026amp; Charging\u003c\/p\u003e\n\u003cp\u003eT40 Batteries \u0026amp; Charging\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.

Is the module bad?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eProbably not. That pattern says the charger is happy on a stable supply and unhappy on the one in the field, which is a supply problem until proven otherwise. Check what else is drawing from the generator, how long and how heavy the cord run is, and whether the generator holds its output when the charger tries to pull. Measure at the charger inlet while it is loaded, not at idle. Then try a different receptacle on the same generator before spending money on a module.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe breaker trips the instant I plug it in. What does that tell me?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA trip at the moment of connection, before any battery is involved, is an inrush or input-side event rather than a charging fault. It can be a failed inrush limiter or bypass relay, a shorted input component, or simply a breaker too small for the surge the charger draws at switch-on. Try a different circuit with adequate capacity first. If it still trips instantly on a known-good supply, the fault is inside the unit and the input stage is where to start.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIt powers up normally, then quits as soon as I connect a battery. Is that this module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUsually not. If the display lights and the fans spin, the input stage is delivering enough power to run the charger, so a failure that appears only under load has moved downstream. Look at the output stage, the battery cable, and the battery itself before condemning the AC module. Swap in a known-good battery and a known-good cable one at a time. If the shutdown follows the battery rather than the charger, you have your answer without opening anything.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThere is a rapid clicking inside when it powers up. What is that?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThat is a relay trying to pull in and dropping out again, and it has two common causes. Either the supply is sagging so far under inrush that the coil cannot hold, which points back at the cord, the receptacle, or the generator, or a protection circuit keeps detecting a fault and cycling. Test on a strong, short supply first and see whether the clicking stops. Persistent chattering on a known-good supply means the fault is internal and belongs on a bench.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I tell the AC module from the DC output module inside the charger?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFollow the wiring rather than the shape. The AC module sits on the input side, so its heavy connections trace back toward the mains inlet, the fuse or breaker, and a filter section built around a common-mode choke and film capacitors, usually with a relay close by. The output stage sits toward the battery cable with its own magnetics and heavy DC terminals. If the assembly in your hand wires back to the socket you plug into the wall or the generator, it is the input side.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThere is a burnt smell but I cannot see any damage. Where do I look?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUnderneath and behind. Vented components often leave their mess on the board below or on the enclosure wall rather than on top, so where the service procedure allows the board to be lifted, look at the solder side, under the heat sinks, and at the enclosure surfaces facing the board. Look for brown heat shadow, dried residue, and fine dark tracking lines between conductors. Smell it in sections as well, because a scorched coating, a cooked capacitor, and a burnt connector do not smell alike up close.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe charger sat out overnight and now it will not start. What should I check first?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCondensation and what it has already done to the mains side. Open the enclosure somewhere dry, let the unit warm and dry thoroughly before any power is applied, and inspect for dew staining, corrosion at terminals, and fine dark tracking between adjacent conductors where damp and dust have combined. Check the input cord and plug too, since they get stood in wet grass and are easy to overlook. Powering up a damp charger is how a survivable soaking becomes a destroyed board.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I really need to put the ground strap back?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, and it is not optional. On mains-powered equipment the bonding strap between the enclosure, the chassis, and the incoming ground is what keeps an internal fault from putting the case at a dangerous potential. Reattach it before anything else goes back, onto clean bare metal, using the serrated or star hardware it came off with. A ground screwed down onto paint or powder coat looks connected and is not, so scrape back to bright metal if the surface has been refinished.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow should I clean dust out of the charger while it is open?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDry, low-pressure air aimed so debris leaves the enclosure instead of packing in under an adjacent board, plus a soft brush for anything felted onto a fin stack or an intake screen. Do not flood a coated board with solvent, and do not put a shop compressor at full pressure against tall components or fan blades. Clean the fans and the intake screens as thoroughly as the board itself, because that is usually where the airflow is actually being lost.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I replace the fans while the charger is open?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIf they have any age on them it is usually the right call. Fan bearings in field equipment run hot and dusty, and a fan that still spins freely on the bench can be turning far slower than it should once it is working against a loaded enclosure. Most of the labor is in getting the enclosure open, so changing tired fans while you are already inside costs little and removes one of the most common reasons a replacement power module fails early. Check the ducting and screens at the same time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe module I took out has no visible damage. Did I misdiagnose it?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNot necessarily. Power semiconductors and solder joints fail without leaving any external mark, and a cracked joint under a heavy component can open only once it is hot. Before deciding, confirm that the replacement actually cured the symptom on the same supply and the same battery. If it did not, put the effort into the input path and the output stage instead. Keep the old module labeled with what it did rather than binning it, because a known-history spare has value on a bench.\u003c\/p\u003e\n\u003chr\u003e\n","brand":"DJI","offers":[{"title":"Default","offer_id":53027335602496,"sku":null,"price":1299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/0159\/0848\/files\/IMG-2427.png?v=1787758034","url":"https:\/\/aresacres.com\/products\/dji-agras-t40-oem-charger-ac-power-module-charging-station-ac-module","provider":"Ares Acres","version":"1.0","type":"link"}
