Overview
TP-P1.5 is an airborne DC-DC module for tethered drones with 360-400VDC input, 24VDC nominal output (22.5-25.5VDC range), 1.4kW rated and 1.5kW peak output, weighing ≤380g. 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.
The input cable uses 18AWG soft silicone-insulated model-aircraft wire, specified for 7 A, -20–80°C and 600 VDC insulation withstand. Positive is red and negative is black. The 300 V value is the input undervoltage threshold, not the cable voltage rating. Overcurrent protection acts immediately at 63 A.

System selection guidance
TP-P1.5 should be selected as part of the complete tethered UAV power chain, not from the kW rating alone. We review 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.
FAQ about TP-P1.5
What type of UAV is TP-P1.5 designed for?
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.
Does the original battery remain installed during tethered operation?
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.
What is the difference between rated and peak power on TP-P1.5?
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.
Is 410-420VDC part of the normal input range?
No. The English manual identifies 360-400VDC as the operating input range and 410-420VDC only as a maximum-limit input condition.
Can TP-P1.5 be selected only from the drone battery voltage?
No. We also check actual continuous power, peak power, payload, tether length and operating environment before confirming the configuration.
Can the output or connectors be customized?
Project-specific adaptation can be evaluated by us according to the UAV electrical interface, mechanical installation and mission requirements.
