According to the latest achievements of power electronics, our company has introduced a special power supply for electrodialysis combined with advanced control methods. The special electrodialysis power supply produced by our company adopts advanced PWM pulse width modulation technology and uses imported IGBT cargo MOSFET as power switching device. It is small in size, light in weight, full in function, stable in performance and reliable in production process. This series of products adopt the advanced DSP control system, with the function of automatic steady flow/steady pressure, which does not change with the voltage and has high reliability.It has the extended function of PLC interface and RS465 interface, which is convenient for automatic control.
