Power board

Always ready to serve

The Power Board (PB) is a small, lightweight and efficient device to be used in piston engine UAVs in conjunction with a three phase brushless generator or brushed generator.

Electrical power to the PB is supplied by a generator. It provides direct current with low ripple to the system, simultaneously managing charge of the backup battery.

Providing a versatile backup battery

The Alpha 800 back-up battery is used:

  • As the primary power source in case of generator failure
  • As the primary power source if the generator supplies more than the estimated (30 volts) of charge, causing the power board to cut-off supply to protect the electronic systems
  • During prefight checks when the engine is off or RPMs are low

External power can be supplied to charge the battery on the ground or for preflight checks.

The battery must be 5 cell LiFeP04 16.4V at 18V charging unless the battery in use is a customized version.

The PB is enclosed in a light aluminum extruded case and the connectors used are industrial high quality. A IP67 aluminum milled case can be supplied upon request.
