Power Cube electrical power-management product

The Mauch Power Cube 3 is a PMU module for multirotor and fixed-wing UAVs: a power management unit that takes the main flight battery voltage and delivers regulated supplies to the flight controller, servos and payload electronics. It is built by Mauch Electronic in a carbon-fibre enclosure with a cooling fan.

The input accepts 4S to 14S battery packs with a maximum of 60 V, which covers small multirotors up to large heavy-lift platforms on high-voltage packs. The module has three output channels. Outputs 1 and 2 supply 5.3 V at 10 A each, and output 3 supplies 12.0 V at 10 A. Output 1 is fixed at 5.3 V, while outputs 2 and 3 can be set to other voltages on request, which lets an OEM match servo or payload supply voltages to the aircraft.

Separate regulated channels let an integrator keep the flight controller supply apart from servo and payload loads, so a load fault on one channel is less likely to disturb the flight computer. A fan-cooled enclosure addresses the dissipation of the regulators at high input voltage and high output current.

Supplied cabling is part of the integration. The Power Cube/Pixhawk 2.1 cable has Clik-Mate 6-pin connectors at both ends and is 200 mm long. A backup version of this cable adds a JR connector for a second supply path to the flight controller. A 12.0 V output cable offers one Clik-Mate 6-pin connector and three JR connectors, again 200 mm long, and a 150 mm sensor cable is listed. The Power-Switch is a separate item and has to be ordered on its own.

Typical applications are professional drones and UAS that use a Pixhawk-type flight controller and need a robust, multi-output supply derived from a single high-voltage battery, together with voltage and current monitoring for power telemetry.
