Power Distribution Unit

Power distribution unit for Penguin BE electric UAV

Key Features

The power distribution unit efficiently converts the main battery voltage into 6V and 12V power outputs for the onboard electronics. Power distribution unit comes pre-installed in Penguin BE with all necessary wiring, mounts and connectors.

Despite small size, power distribution unit offers outstanding efficiency as well as unique features such as the ability to monitor load, battery current, engine rpm and battery voltage through TTL serial communication. All power distribution parameters can be transmitted to the ground station and monitored during the flight.
