The series will be three-phase AC power from the step-down transformer, and then get through the bridge rectifier 220 volts DC. The device by the automatic air switch, transformer, two or three phase bridge rectifier assembly, DC contactors and other major components. Set a short circuit, over voltage protection. When controlled solenoid capacity greater than 19 kWh, rectifier transformer, attached; when controlled solenoid capacity less than or equal to 4 kWh, a single-phase bridge rectifier.
