Thyristor-based frequency converters type TMK with output frequencies of 0.2 - 10 kHz are designed to supply power to equipment that incorporates technology now used in induction heating, hardening, smelting and/or other applications where a parallel (or in some cases, parallel-serial) resonant circuit is required.
Small thyristor-based frequency converters type TMK-R for supplying power to smaller induction heaters, melting furnaces and other technological devices that require up to 100 kW of power and working frequencies of up to 10 kHz..
Transistor-based frequency converters TRMK with output frequencies of 6 - 50 kHz are designed to supply power to equipment that incorporates technologies such as induction heating, hardening, smelting and/or other applications where a parallel resonant circuit is required.
