Mobile ground power unit

for aircraftrunwayAC/DC

The Transformer-Rectifier provides 28.5 volts DC (nominal) to supply necessary energy for aircraft with 28-volt DC power requirements. The DC voltage is derived from a 400 Hz source (furnished by others), which is connected to the input of the Transformer-Rectifier unit. A massive 12 pulse, silicon rectifier/heat sink assembly with a sophisticated, controlled step down transformer provides smooth DC for the load. Four highly reliable fans provide efficient forced cooling for all components within the Transformer Rectifier unit. The Transformer-Rectifier may be connected to the external 400 Hz source via a standard aircraft receptacle mounted on the rear of the Transformer-Rectifier or, alternately, via hard wired conduit connection in place of the receptacle. The Transformer-Rectifier could be mounted on a portable generator, portable cart, or upon a passenger loading bridge. The low profile of the Transformer-Rectifier unit allows mounting to the underside of a passenger loading bridge cab next to a point of use converter without causing ground DC Output 28.5 volts nominal, in accordance with MIL-STD-704E voltage limits Control panel with Digital Voltmeter, Digital Ammeter, Output ON/OFF Buttons, Output ON Indicator, 400Hz Input Indicator, Current Limit (Soft start) Adjustment, Current Limit Disabled Indicator, Current Limit ON/OFF Control Four Fans in high performance push-pull configuration Over Temperature Protection Self-resetting thermal switches on rectifier heat sinks Output Bus Bars at rear of unit, Plated Copper with Bolted Connections Weather Resistant Construction Powder Coat Finish in High Gloss White or PAGE Green
