BC 400 – 400 Hz Control Box
Tarmac-side control box for managing 400 Hz aircraft ground power supply functionality at the connector level.
About This Product
Control box used on the tarmacs to control the functionalities of the 400 Hz power supply at aircraft connector's level.
The 400 Hz frequency is the standard for aircraft ground power because it allows for lighter, more compact power supply and distribution components compared to 50 or 60 Hz mains power. Ground control boxes like the BC 400 give ramp operators local command of ground power output to parked aircraft — critical during pre-flight power-up, cabin servicing, and maintenance operations.
