It converts single-phase AC mains power into 800V high-voltage DC at the ground station, transmits it via reinforced tether cable to the aircraft, and steps it down to a stable 50V at 4kW output at the airborne unit -- powering both the M400's propulsion system and its mission payloads continuously for as long as AC power is available.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 800V transmission architecture operates at half the current of a conventional 400V design, reducing cable heat generation to one quarter and allowing the use of a lighter, longer tether without meaningful line loss.
