Overview
TP-P5 is an airborne power module for tethered UAVs with 680-800VDC input, 24VDC nominal output (23.5-24.5VDC range), 5kW rated power, 210A rated and 220A maximum current, and approximately 2.2kg weight. TethPower TP-P5 is a 5kW high-current airborne DC-DC power module for tethered UAV platforms operating on a 24V-class power bus. It converts 680-800VDC tether input into a regulated 24V output with 210A rated current.
TP-P5 is designed for applications where a low-voltage UAV bus requires substantially more current than smaller airborne converters can provide. Its 2.2kg enclosure integrates forced-air cooling, IP54 protection and outdoor-oriented environmental treatment.
Features
- 5kW regulated output for 24V-class high-current UAV buses
- 210A rated current for demanding low-voltage aircraft power systems
- 680-800VDC tether input to reduce transmission current on the cable side
- Integrated forced-air cooling and IP54 enclosure
- Protection against input faults, output overvoltage, overcurrent, short circuit and overtemperature

System selection guidance
TP-P5 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-P5
Why does a 24V module need such high output current?
At lower voltage, the same power requires more current. TP-P5 is designed for 24V-class platforms that need up to 5kW of airborne power and therefore require a high-current output path.
What is the maximum output current?
The manual specifies 210A rated current and 220A maximum current.
Is there a separate peak-power rating?
Rated output is 5 kW. No separate peak-power rating is specified.
Can TP-P5 be used on a 48V or 60V UAV?
Not as the standard configuration. TP-P5 is a 24V-class module. We should review the aircraft bus voltage before recommending another module or a customized configuration.
Does long tether length affect TP-P5 selection?
Yes. Tether resistance, voltage drop, cable current and airborne weight must be evaluated together with the 680-800VDC input requirement.
