The series inverter mode of SCR intermediate-frequency power supply is series resonance intermediate frequency power supply. At present, the energy saving induction melting power supply of intermediate frequency melting furnace features one power supply supporting two furnaces. An intermediate frequency power supply can drive two electric furnaces working at the same time. In addition, the output power of the smelting furnace is distributed arbitrarily on the two electric furnaces, and the power factor is larger than 0.95 SCR series inverter, and the control conversion can be turned off in time to avoid interference; Constant power output helps to improve work efficiency; Digital control system is accurate and stable, functioning fault self-diagnosis; In has graphical operation interfaces, achieving full monitoring of working parameters, working conditions and failure points. Features of intermediate-frequency series resonance power supply:

1. Intermediate-frequency melting furnace features one power supply supporting two furnaces, and the output power is distributed randomly between the two furnaces.
