Switch-mode power supplyThe Frequency converter IPPI-5000-25 AC resistance furnace pulse power source is used for power (temperature) regulation and stabilisation.
Power regulation occurs via control angle variation of the thyristors that are located on the step-down transformer's primary side. Current, Voltage, Power and Temperature stabilisation means are provided.
Switch-mode power supply IPPI-65
The frequency converter is used as part of a high frequency heating technological complex, like a wide diameter pipe bending machine
