Airborne Power Module for Tethered Drone Systems High-Voltage DC to Low-Voltage DC Converter

This 4KW airborne power module is a high-voltage DC to low-voltage DC converter designed for tethered drone systems and other demanding airborne applications. It converts 750V DC input into a stable 50V DC output, delivering up to 4000W of power with high efficiency, compact size, and lightweight construction.

Built with a high-strength aluminum alloy enclosure, the module is engineered for reliability in harsh operating environments. It features isolated DC-DC conversion, intelligent fan cooling, and a full set of protection functions including input under-voltage protection, input over-voltage protection, output over-voltage protection, over-current protection, short-circuit protection, and over-temperature protection.

With an efficiency of up to 97%, this power module helps provide stable and reliable energy for tethered UAV platforms requiring long-endurance flight, while maintaining excellent thermal and electrical performance.
