500v 60a ELECTRODIALYSIS POWER SUPPLY for water treatment with 4~20mA interface
Introduction of electrodialysis power supply
Water treatment electrodialysis is becoming more and more popular. According to the latest electronic research results, combined with advanced control methods, our company has designed a dedicated electrodialysis power supply. This electrodialysis rectifier uses advanced pulse width modulation technology, and uses high-quality IGBT modules and MOSFETs as power switching devices.

Working principle of electrodialysis power supply:
The electrodialysis power supply is mainly composed of a rectifier filter circuit, a full-bridge conversion circuit, a high-frequency transformer, a high-frequency rectifier, a filter circuit, an auxiliary power supply circuit, and a main control unit circuit. The main control unit circuit is mainly composed of a phase failure protection circuit, a temperature protection circuit, an overload protection circuit, a short circuit protection circuit and a PWM circuit with PI adjustment.
After the three-phase grid voltage is switched by the electrodialysis power supply, and then rectified and filtered, a 520VDC DC stabilized power supply is obtained and supplied to the inverter circuit. The inverter circuit is mainly composed of a high-power field-effect MOSFET module (or IGBT module) to form a full-bridge conversion circuit. When the PWM output control signals respectively drive the power modules through isolation, the two sets of diagonal tubes are turned on alternately. Under the high-frequency transformer primary high-frequency pulse voltage, the secondary voltage is supplied by the high-frequency transformer rectifier to the load.
high processing speed and so on.
