    SCR control system of intermediate frequency power supply, rectifier control and power regulation is triggered by the rectifier and inverter control and protection, etc. Rectifier trigger adopting digital circuit provides the silicon controlled rectifier bridge all trigger pulse. Complete power rectifier control work, current limit, the limit of voltage and current feedback, through the pressure protection control. Inverter control adopts timing phase locking function and provide reliable SCR trigger drive pulse, guarantee the equipment with strong anti-interference ability and stability, the main technical as below:
1)Rated parameters:  the output power P, output frequency F, output voltage UN, output current IH, three-phase input current IN
 2) Power factor:  Cosφ≥0.92
 3) The power electricity efficiency: η≥94%
 4) Power source with current limit, limit voltage, over current, over voltage, low water pressure protection, etc
5) Power supply has the function of internal control and external control, internal control manual start-stop and adjusted work; When external control by PLC, adjustable power signals for the standard voltage (0 q-- 10 v)
6) The voltage and current double closed-loop control, the constant voltage of the voltage operation function that sense should not change according to the external factors (such as in the line voltage, load impedance, etc.)
7) The power supply has the operation parameters and the signal output function, display control for system
8) Starting the device is convenient, can guarantee the success rate of 100% of the start, power adjust range 10% to 100%
9)Power been running in the factory before shipment.
