TethPower TP-P1.5 is a compact 24V airborne power module for lightweight tethered UAV systems. It converts 360-400VDC tether input into a 24V-class output for aircraft and payloads that require continuous power during long-duration missions.
With a total weight of no more than 380g and a compact 103 × 53 × 50mm body, TP-P1.5 is suited to UAV platforms where payload margin and installation space are limited. The module supports seamless battery switchover and is widely applicable to tethered lighting, surveillance and other persistent airborne operations.

TP-P1.5 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.
TP-P1.5 is intended for lightweight tethered UAV platforms using a 24V-class power architecture. Final compatibility depends on the aircraft voltage range, continuous and peak power demand, payload and mounting conditions.
In typical integrations, yes. The onboard battery can remain connected as backup power. TP-P1.5 is designed to switch to battery support without a transient voltage drop if tether power is interrupted.
Rated power is 1.4kW for sustained operation under specified conditions. Peak power is 1.5kW for short-duration load demand. System selection should consider both values.
No. TethPower also checks actual continuous power, peak power, payload, tether length and operating environment before confirming the configuration.
Project-specific adaptation can be evaluated by TethPower according to the UAV electrical interface, mechanical installation and mission requirements.
