KGPS-Series Medium Frequency Induction Heating Power Supply

KGPS-Series Medium Frequency Induction Heating Power Supply

Description:
KGPS-series medium frequency induction heating power supply adopts three phase bridge thyristor voltage regulating rectifier, inductance capacitor filter, quick SCR H bridge resonant inverter and DSP microcomputer digital phase-locked loop control technology. Medium frequency heating power supplies have perfect protection functions and communication interface functions. The output heating power is continuous and adjustable and the frequency is stable. With good human-computer interface and nice visibility, this induction heating power supply can automatically store and record DC current curves of output heating power, DC voltage and DC current timely. Medium frequency heating power supplies can be extensively used in aviation, aerospace, weapon, ship, metallurgy, machinery manufacturing and other enterprises' medium frequency induction heating furnaces.
