The Tronair 28V DC aircraft rectifier / ground power units provides DC ground power to the aircraft while in the hangar or on the ramp. These units operate on 3 phase input voltage - 60 HZ. (50 HZ models are available)

Many systems and devices in the aviation industry, and other fields, require a DC voltage of 28 volts. As this cannot be supplied by the utility directly, converters are employed which supply the necessary voltage and eliminate supply irregularities to a limited extent.

Normally these units are used to supply smaller aircraft with electric power. There are special reasons why aircraft need a 28V DC voltage for internal supply. They save costs in maintenance and operation, and also for environmental reasons, aircraft are supplied by external electrical power supplies when they are parked at airport terminal stands with their engines shut down.
