Medium High Frequency Melting Power Supply - China

I.

Product Introduction

As a medium- frequency induction melting power supply, IGBT inverting medium ( high) frequency induction melting power supply series adopts three- phase bridge rectification power supply, IGBT power device full bridge inverting and load- matching medium- frequency transformer made of ultracrystallite alloy materials and realizes adjustable medium- frequency output power by LC series resonance working mode.

In the entire work process, it adopts power closed- loop control, the working frequency follows the loaded inductance value changes of the induction coil automatically, with whole- course soft switching control, it generates little electromagnetic interference.

With its power factor more than 0.92, power conversion efficiency higher than 0.96 and multiple control signal selections, it is really an ideal energy- saving power supply substituting for medium- frequency generating sets and SCR medium- frequency melting power supply.

IGBT medium- frequency induction melting power supply series is convenient to operate and use, has a wide range of phase- lock frequency and adaptable to various induction coils.

It can be widely used in vacuum or anti- vacuum metal smelting and electromagnetic levitation melting.
