100 W Generator Power Unit (GPU) is designed to provide onboard dual voltage regulated power supply for the unmanned aircraft vehicles.
Despite small size, power unit offers outstanding efficiency as well as unique features such as the ability to monitor load, battery current, engine rpm, generator and battery voltage through TTL serial communication. All power distribution parameters can be transmitted to the ground station and monitored during the flight.
Generator power unit can be used with brushless or brushed generators that have a voltage output within 10-35 Volts and 13-50 Volts respectively. Integrated Lithium Polymer charger is used for the backup battery, which is switched on during the pre-flight checks, power peaks, or in the event of the engine failure.
Power unit is packed in a sealed aluminum enclosure and fitted with the high-end industrial push-pull connectors.
