Thyristor frequency converter TMK630/1,5/0,6

Thyristor frequency converter TMK630/1,5/0,6

Thyristor frequency converter has been made for HKS Forge, s.r.o.Trnava. Together with three-phase separating transformer and the load of a parallel oscillatory circuit for supplying power to an inductive heater.
Thyristor frequency converter consists of input power circuit breaker, controlled rectifier, smoothing choke, current inverter, and overvoltage protections. The operation of the frequency converter is ensured by operating system consisting of regulator, converters and Programmable Logic Controller (PLC). Internal water cooling system is used for cooling electronic and other parts of power circuits of frequency converter.
