TethPower TP-P12 50V is a 12kW airborne DC-DC power module for heavy-lift tethered UAV systems requiring a regulated 50V power bus. It converts 900-1000VDC tether input into a 50V-class output with 240A rated current.
At 3kg, the module is designed for aircraft where sustained high power, high current and outdoor protection are more important than ultra-light integration. IP65 construction and ≥97% efficiency support demanding long-duration industrial missions.

TP-P12 should be selected as part of the complete tethered UAV power chain, not from the kW rating alone. TethPower reviews the aircraft battery/DC-bus voltage, continuous and peak demand, payload, tether length, cable voltage drop, operating altitude, temperature and ground-power architecture before confirming a matched configuration.

Answers to common compatibility, configuration, quotation, and delivery questions.
Not automatically. Nominal battery voltage alone is not enough; full-charge voltage, aircraft bus limits, continuous/peak power and battery-parallel behavior must be confirmed.
The manual specifies 240A rated output at a 50V-class bus.
No separate peak-power value is stated in the current manual. The confirmed continuous rating is 12kW.
The 50V version is specified for 900-1000VDC input, with 950VDC rated input.
At this power level, tether voltage drop, connector current, thermal management, aircraft payload margin and backup-battery integration all become critical parts of the design.
