AT-400 Power Supply

This reliable, three-phase, SCR rectified, constant potential DC power source provides arc voltages between 18-40 volts, permitting operation between 100-400 amps at 100% duty cycle. An optional cap bank is available for spraying zinc wire down to 50 amps. The cooling fan operates only when needed, minimizing dirt, dust, and moisture buildup within the power supply thereby minimizing maintenance.
