â—† IF power both main circuit and control circuit adopt fully digital control wiring; the regulator part is three phase whole control circuit; contravariance is shunt chopper; power can be adjustable between 5%-11% of nominal rating.
â—† Reliable starting performance which can reliably starting no matter whether there is workpiece in the sensor or not.
◆ Adopted inner ring current and IF voltage double closed loops system ensures high stability of device. Input voltage swings among ±10% and output voltage with stable precision ±1%, ensuring temperature consistency of steel inside inductor during heating.
â—† Protection device such as overcurrent, over-voltage, water pressure, fuse wire guard the safety of power electronic device.
â—† Automatic frequency t rack uses phase locking controlling which can keep inverter work safely and economically.
â—† All integrated components fixed on one control panel
â—† NO phase sequence requirement on coil in, and polarity requirement on coil out. Zero voltage starting causes no current rush.
â—† All parameter adjusted before machine leaving factory. No need commissioning on site, end user can operate machine directly.
