Almost all 28V DC power supplies in this range are mains powered units, with the exception of the TC400/28 units which is a battery unit.

The RBSC and RBPS range of 28V DC power supplies are specifically designed and built by Red Box to provide the cleanest possible DC power unit. The products range from 25 amps up to 600 amps, higher power units are available on request. The units are able to switch between two voltages, set at 14V and 28V as standard, but you may have this set at different voltages on request.

The TC400/28C is a battery powered continuous power supply allowing continuous power for a limited time only. An amber beacon is fitted to indicate low voltage on the unit. By monitoring the voltage of the unit you can also use this unit to start the aircraft.

For starting only requirements we have either lead acid units or lighter lithium 28V start units. The 28V DC power range expands to provide a combination of starting and continuous power from a mains electrical supply for use on the apron or flight line our HybRED or battery powered systems.
