Overview
TP-P24 is an airborne DC-DC module with 850-1000VDC input, 58.5VDC rated output (55-59VDC range), 24kW rated and 26kW peak power, continuous 24kW operation at -20°C to +40°C, and ≤9.5kg weight. TethPower TP-P24 is a 24kW airborne DC-DC power module for high-power tethered UAV platforms using a 58.5V rated aircraft bus. It converts 850-1000VDC tether input into a regulated 55-59VDC output with 400A rated current and up to 26kW peak output.
Designed for heavy-lift and mission-intensive platforms, TP-P24 combines IP65 protection, ≤9.5kg net weight and ≥97% efficiency. The manual specifies continuous 24kW operation from -20°C to +40°C, making thermal and environmental matching an important part of system selection.
The input-overvoltage recovery threshold is ≤1000 V. This threshold does not specify an automatic restart mechanism.

System selection guidance
TP-P24 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-P24
Is 26kW the continuous rating of TP-P24?
No. The confirmed continuous rating is 24kW. The manual specifies 26kW as peak output.
What ambient temperature applies at full continuous power?
The manual specifies -20°C to +40°C for long-term 24kW operation. Environmental derating should be evaluated outside this condition.
What aircraft payload margin is required?
The module itself weighs up to 9.5kg. The complete calculation must also include payload, mounting hardware and tether lifting force.
Why is a high-voltage tether necessary at this power level?
Transmitting 24kW at a high tether voltage reduces cable-side current, helping control conductor size, voltage drop and airborne cable mass.
Can TP-P24 support cleaning or firefighting missions?
It can be evaluated for high-power cleaning, firefighting-support and other heavy-lift applications when aircraft voltage, propulsion power, payload and tether requirements are compatible.
