FAST SWITCHING THYRISTOR FOR INDUCTION HEATING FURNACE

Fast switching thyristor is the core component of induction furnace power supply & thyristor frequency converter.

Thyristor frequency converter consists of rectifier bridge and inverter bridge.

Fast thyristor usually used as inverter circuit,phase control thyristor used as rectifier circuit.Two or four fast SCR in series in the inverter circuit.

COMPANY

We have a wide current range fast switching thyristor which used on inverter bridge.

For example KK800A/1000V-1800V,KK1000A/1000V-2000V,KK1200A/1000V-2000V,KK1500A/1000V-2200V,KK2500A/1800V-2800V,KK2700A/2000V-2800V,KK3000A/2000V-4500V,KK3500A/3000V-4500V,KK4000A/3000V-4500V ETC.

These part numbers replace westcode R series SCR with good quality,and has successfully used on Inductotherm brand furnace,Ajax brand furnace,Germany ABP brand furnace…
