Variable Power Supply Units

At the beginning of 2009, SC has finished manufacturing a motor-driven 3-ph, 1000 kVA variable power supply unit. The variable-voltage transformer and its enclosure have been completely manufactured in SC's workshops with VPI technology. This unit has an input of 0-400 V transformer, output range from 0.05 to 11.5 kV. Voltage varies smoothly in small taps and un-disconnectedly. at 6kV and 11 kV the unit can deliver maximum capacity.
