Tethered Power System · DJI Matrice 400 (H)

Keep your Matrice 400 (H) flying. Non-stop.

The Matrice 400 (H) variant with the G100-M400 high-power ground unit targets the heaviest payloads and the longest tethered endurance — 24 h+ on station with 3,000 W of stabilised airborne power. The tool-free airborne module (850 g) feeds the drone directly over a high-voltage tether from the 7 kW ground unit. If ground power is cut the drone flies and lands normally while the cable auto-retracts; cable break, disconnect or short-circuit trigger instant HV cutoff.

System architecture

How the G100-M400 keeps power flowing

1

Ground power

Mains or generator — single-phase 220 VAC, 50/60 Hz.

→
2

Ground station

10.5 kW converter, motorized winch, comms, cooling and control in a 21.8 kg case.

→
3

High-voltage tether

High-voltage DC over 110 m or 220 m of heavy-duty cable, auto-retracting.

→
4

Airborne module

780 g unit in the battery bay outputs a regulated 51.5 V at 3,000 W.

→
5

M400 (H) + payloads

L48 floodlight, camera, speaker or drop system — fed continuously.

Ground station — G100-M400

The G100-M400 is the high-power ground end for the Matrice 400 (H): a 10,500 W AC/DC converter, servo-driven winch, communication module, cooling system and control electronics in a 21.8 kg tether box. Cable pays out and retrieves adaptively through take-off and landing, and the station display, handheld terminal or PC client shows live voltage, current, cable length, runtime and fault records. Over/under-voltage, over-current, over-temp and short-circuit protection auto-recover; power-loss, over-unspool and cable-break protection are built in.

Airborne module — 780 g battery-bay swap

The 780 g module swaps into the battery bay with the same quick-release interface — tool-free, no drone modification. It converts the high-voltage tether input to a constant 51.5 V output rated 3,000 W that feeds the aircraft and payload ports directly, so onboard packs stay above 90% as a cold backup for the entire flight. IP54 housing; the module reports its status to the ground station over the same cable.

Applications

What 24 hours of hovering is for

Matched to what a DJI Matrice 400 (H)-class platform can actually carry — lighting, comms, cameras and speakers.

Emergency Rescue & Disaster LightingHours of continuous aerial lighting for earthquake, flood and wildfire response — with HD video and thermal monitoring for on-site command.
Communication Relay & Temporary NetworkQuickly deploy a temporary aerial communications node over mountains, disaster zones, islands and large construction sites.
Facade Inspection & Building SurveyLong-duration close-up inspection of facades and curtain walls with HD and infrared sensors — no scaffolding or rope access required.
Firefighting & Fire MonitoringCarry thermal imaging, loudspeakers and firefighting payloads for prolonged fire monitoring, personnel command and auxiliary firefighting.
Facade Cleaning & High-rise MaintenanceContinuous high-altitude washing of exterior walls and curtain walls with spray or brush tools — faster and safer than manual cleaning.
Broadcast & Cinematic AerialContinuous stable power for extended hovering — fewer battery swaps, better broadcast continuity and steadier footage.
FAQ

Questions buyers ask first

Do I need a generator, and which one?
The ground unit runs on standard single-phase 220 V AC (G300 series: three-phase 380 V AC). For field operations without grid access, pair it with the 6.5 kW generator (peak 7 kW, 14 L tank) matched to the G100-M400 system with the L48 floodlight per the manual (priced separately above).
What does the kit price include, and what is the MOQ?
each configuration (110 m or 220 m) includes the ground power unit, airborne module, tether cable and custom-foam carry case. MOQ is 1 set; final quotation may vary with quantity. Payloads and the generator are optional add-ons priced separately.
Which cable length should I choose?
Longer cables reach higher altitudes at a small output-power cost. Shorter lengths suit most urban and inspection tasks, while the longest spans serve high-rise, bridge and heavy-lift scenarios. Custom lengths are available on request.
What happens if ground power is cut?
The drone keeps flying and lands normally on its own battery, and the tether auto-retracts so the cable never fouls the landing spot. Cable break, short-circuit and disconnection trigger HV cutoff protection.
Can the payloads be used together?
Yes. the 4,800 W (L48) floodlight and the PA speaker share the same quick-mount interface; the matched 6.5 kW generator pairs with the ground unit for off-grid missions.
What about certification, shipping and warranty?
Tethered systems ship with CE documentation; batteries follow UN38.3 transport rules. Standard warranty is 12 months with lifetime technical support and spare-part supply. Final certificates are provided with each shipment.
