G400-36K Universal Tethered Power System
G400-36K · 36,000 W constant-stabilized tethered power for drones with a maximum take-off weight of 165-200KN The onboard module replaces the drone’s flight battery and feeds regulated HV DC from the ground — 24 h+ on station with the original pack held as an untouched reserve. Universal fit means one ground unit powers any brand in the rated MTOW range.
How the G400-36K keeps power flowing
Ground power
Three-phase 380 VAC mains or generator — 380 V ±10%, 3-phase 5-wire, 50 Hz.
Ground station
G400-36K ground station: AC/DC converter, motorized winch, comms, cooling and control in one case.
High-voltage tether
800–1000 VDC (default 1000) over a lightweight cable, 110 m, 220 m or 330 m, auto-retracting.
Airborne module
9.4 kg module in the battery bays steps voltage down to a regulated output.
Drone + payloads
165–200 kg-class heavy-lift drones — camera, light, speaker, drop or relay, fed continuously.
Ground station — G400-36K ground station
One wheeled case holds everything: the AC/DC converter turns the site supply into 800–1000 VDC (default 1000) at rated 40 kW (50 kW peak), the servo-driven winch pays out and retrieves cable automatically (cable tension 0–50 N, retract 0–5 m/s; optical-fiber link optional), and the integrated display, Bluetooth and Type-C links expose live voltage, current, cable length and fault logs to the station screen, a handheld terminal or a PC client. Cooling, cable-break detection and power-fail auto-retract are built in.
Airborne module — battery-bay swap
The 9.4 kg module mounts on reserved threaded holes with the airframe’s own fixings — no brackets, no rewiring. It converts the high-voltage tether input to 58 V, 75 V or 100 V DC, rated 36 kW (42 kW peak) via bare leads, feeding the aircraft and payload ports directly, so onboard packs stay above 90% as a cold backup throughout the flight. Input and output connectors are keyed and waterproof; the module reports its own status to the ground station over the same cable.
