Main characteristics:

With IGBT power component and current inverting technology, the output oscillating frequency can range from 1KHZ to 20KHZ and parallel oscillating circuit is used.  small size , compared with SCR controlled machine, only 1/10 working space is needed, greatly reduce occupation space.High efficiency and energy saving, a high power factor and power efficiency within the scope of full power.With wide frequency range from 1-20KHZ automatic tracking ability, no need adjustment at scene. 100% duty cycle , 24hours continuous working ability at maximum power. Constant output voltage or power control modes are alternative;Full display of output power, output frequency, output voltage and current.simple operation: operation can be learned in a one minute.simple installation: connect the machine to 3phase 380VAC and cooling water only.timer can be chosen to preset and adjusted the heating time, heating power, retaining time, retaining power respectively to control the heating curve and heating temperature.

Advantages of current inverting control technology:

Current inverting control technology ,soft-switching responance dual-control and frequency tracking technology are used to guarantee the smooth working at a large frequency of 1 to 20KHZ.With the current inverting control technology, parallel oscillating circult is realized that leads the unique characteristics of medium frequency series generator. with the current inverting control technology, working status of the IGBT can be improved largely, 100% duty cycle can be realized easily to let the machine to work 24hours at the maximum power output.with the current inverting control technology, the reliability of IGBT can be improved in a great step to decrease the repair largely.
