Series-TMK-R Frequency converters are designed for supplying power to smaller induction heaters, melting furnaces and other technological devices with an output of up 60 kW and a working frequency of up to 10 kHz.
Series TMK-R converters consist of a main switch (1), main circuit-breaker (2), anti-jamming module (3), three-phase rectifier (4), intercircuit filter (5), voltage converter with reserve diodes (6), and capacitors (7), making an oscillating circuit together with a medium-frequency transformer (8), and finally an inductor (9) designed such, that an oscillating circuit is created.
Operational tasks and fault monitoring are handled by a PLC coupled with a controller (10). The output requirement is set via the LCD display interface. System failures are also detailed on the display.
Electronic and power circuit components are cooled by an open-loop water system.
Model TMK-R Frequency converters comply with resistance test standards set by ČSN EN 50082-2, ČSN EN 61000-4-2, ČSN EN 61000-4-4, ČSN EN 61000-4-6 and ČSN EN 61000-4-11.
