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.

TP-P5 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.
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.
The manual specifies 210A rated current and 220A maximum current.
No separate peak-power value is stated in the current manual. The product page therefore lists the confirmed 5kW rated power without inventing a peak value.
Not as the standard configuration. TP-P5 is a 24V-class module. TethPower should review the aircraft bus voltage before recommending another module or a customized configuration.
Yes. Tether resistance, voltage drop, cable current and airborne weight must be evaluated together with the 680-800VDC input requirement.
