TP-P70 is a high-power isolated DC/DC module for heavy-lift tethered UAV architectures requiring a 116V-class aircraft bus. The manual specifies a 1600–2000VDC tether input, 116VDC rated output and a 110–118VDC output range.
The detailed electrical specification defines 70kW rated output, 75kW maximum output and 600A rated output current. The IP65 aluminum enclosure uses fan-regulated forced-air cooling and measures 442 × 308 × 128mm ±1mm, with an approximate net weight of 22kg.

TP-P70 is a high-mass, high-voltage module and must be selected as part of the complete aircraft, tether and ground-power architecture. Confirm the 116V bus range, continuous and peak demand, aircraft payload and center of gravity, cooling path, 1600–2000VDC transmission chain, insulation, connector ratings, emergency behavior and site conditions before installation.

Answers to common compatibility, configuration, quotation, and delivery questions.
The detailed electrical table specifies 70kW rated output and 75kW maximum output. Those values should not be treated as interchangeable when sizing continuous operation.
The manual specifies 116VDC rated output with a 110–118VDC output range. Compatibility must be checked against the real aircraft bus, battery and control-system limits.
The source manual describes dynamic current balancing and scalability, including power extension beyond 200kW. The final number of modules, sharing method, wiring and fault coordination require engineering confirmation.
The manual specifies IP65 protection, built-in air cooling, -20°C to +40°C operating temperature and a 3,000m maximum altitude. Actual continuous power depends on the installed cooling path and site conditions.
