TP-P36 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.
The detailed electrical specification states 58.5V rated output with a 54-59V range. The current manual also contains an inconsistent 118V reference in its overview, so the final public page should be released only after engineering confirms the intended output.
No. The detailed table specifies 36kW rated output and 40kW maximum output.
At very high power, increasing transmission voltage reduces tether-side current, which helps manage conductor size, voltage drop and cable weight.
The module weighs about 12.5kg before mounting hardware and tether load are considered. It is intended only for heavy-lift aircraft with adequate payload and propulsion margin.
The manual specifies -20°C to +40°C for prolonged operation at 36kW. Thermal performance must be evaluated for other conditions.
