TethPower TP-P4F is a lightweight 50V-class airborne DC-DC power module for tethered UAV platforms that need high power density without the mass of larger regulated modules. It uses soft-switching technology and an open-loop 8:1 conversion architecture across a 360-430VDC input range.
With 3.5kW rated output, 4.3kW peak capability, IP65 protection and a weight of no more than 0.8kg, TP-P4F is suited to demanding UAV integrations where payload margin, transient power and outdoor operation all matter.

TP-P4F 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-P4F uses an open-loop fixed-ratio style architecture with a 360-430VDC input range and is optimized for low weight and peak power. TP-P4 is a regulated 50V module for higher-voltage tether transmission. The better choice depends on the complete power architecture.
The module is rated for 3.5kW sustained output and can provide up to 4.3kW peak output for short-duration demand. Peak power should not be treated as the continuous operating rating.
No. The manual specifies a 45-53.5VDC output range with 50V typical. Aircraft input-voltage compatibility must be checked before integration.
The module is specified to IP65 with forced-air cooling and an operating range of -40°C to +55°C. Actual power capability can still depend on installation airflow and ambient conditions.
Parallel operation is referenced in the technical design, but the number of units and current-sharing architecture must be confirmed for the specific project.
