Electrical Power Supply
The electrical power supply consists of a steel enclosure with a structural base to which the
system’s main 3-phase transformer is mounted. On the front of the main enclosure is a control
panel where the rectifier instruments and indicator lights are located. The AC to DC rectifier is
mounted in the upper portion of the main enclosure, above the main transformer. Cooling fans are
located below the main transformer and below the silicon-controlled rectifiers(SCRs). Three auxiliary
single-phase transformers are also located in the power supply enclosure. The rectifier control and
isolation boards are mounted in the side control enclosure.
Standard Features
m 380~480VAC, 3 phase, 50/60Hz
m 3 phase full wave 6 pulse rectifier – 6 SCRs
m 6 phase full wave 12 pulse rectifier(optional)
m Monitoring of main transformer and SCR temperature
m Safety functions – LED indication
ü OVERLOAD – the peak current overload circuit is active
ü OUT OF LOCK – a lost phase or high imbalance of the input line
ü LOW INPUT VOLTAGE : control power is below 20% under voltage
ü OUT OF REGULATION : low input voltage, failed SCR fuses or loss of feedback
