  Self Propelled AC/ DC Ground Power Unit  
 
 
 

More than 30 units are in operation for the last 4 years. This unit is being currently used to service and start the Advanced Light Helicopter (ALH) operational with the Indian Air Force, Indian Navy and Coast Guard. This unit uses a 63 cooled 6 cylinder Kirloskar HA694TC turbo supercharged engine. The AC output power from Static Frequency Converter is 40 kVA, 200 V, 3 phase, 400 Hz. The DC output power is 28 V DC, 400 A (continuous) and 1500 A (starting peak) The unit also provides 415 V, 3 phase, 50 Hz commercial power to power the Electrical Hydraulic Trolley and other test equipment.
