Overview
TP-P18 is an airborne power module for heavy-lift tethered UAVs with 900-1000VDC input, 50VDC nominal output (49.5-50.5VDC range), 18kW rated power, 360A rated current and 8.2kg weight. TethPower TP-P18 is an 18kW airborne power module for heavy-lift tethered UAV platforms requiring a regulated 50V-class output at very high current. It converts 900-1000VDC tether input into 50V output with 360A rated current.
With an 8.2kg net weight, IP65 enclosure and ≥97% efficiency, TP-P18 is designed for aircraft where sustained power capacity and outdoor robustness take priority over lightweight integration.

System selection guidance
TP-P18 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-P18
How does TP-P18 differ from TP-P16?
TP-P18 provides a higher confirmed continuous rating at 18kW and uses an IP65 enclosure. It is also larger and heavier, so aircraft payload margin and system need should determine the choice.
What is the rated output current?
The manual specifies 360A rated output at a 50V-class voltage.
Is a peak-power rating specified?
No separate peak-power figure is stated in the current manual.
What payload impact should be considered?
TP-P18 weighs 8.2kg. The complete aircraft calculation should include the module, mission payload, mounting hardware and lifted tether load.
Can this module be paired with any 1000V ground station?
Only after confirming voltage range, continuous power, protection coordination, tether loss and connector/interface compatibility.
