SCR power supply 20kA30V for electrolysis and heating
The SCR power supply 20kA30V system contains two sets of systems, can be used in the field of electrolytic, heating and other applications. The power supply system adopts the primary voltage adjusting and secondary diode rectifier. Each power supply contains a set of voltage adjusting cabinet with thyristor, a set of double anti-star transformer, a set of diode rectifier. The fan forced air cooling mode is used in the power module of the voltage adjusting cabinet.

4.Functions of the SCR power supply
The functions of the SCR power supply has fuse, overvoltage, over current, communication fault protection function, when power failure happens, the fault indicator light and the buzzer will alarm. Meanwhile, the fault information can be queried in HMI.
The rectifier has the advantage of stable and reliable, digital control.
Digital control: the system adopts DSP digital control system, with 64 bits processor control, advanced PID control algorithm, self-adapting voltage and current adjustment, has fast control characteristic.
Stable and reliable: logic controller adopts PLC, circuit design is reasonable, the control strategy is mature, has perfect fault alarm mechanism, can be displayed in the HMI, effectively reducing the damage caused by the fault of power; We use domestic famous products in the main components of power devices ; The machinery has stable and reliable performance.
