The electrophoresis power supply control cabinet is composed of SCR full control module, rectifier transformer, filter circuit, control circuit, power supply system and cooling system. The main circuit adopts a three-phase fully-controlled rectifier circuit, and is designed with an LC filter circuit, the output waveform ripple coefficient is small, the current is smooth and continuous, which greatly meets the needs of the electrophoresis process; the constant voltage closed-loop control circuit uses a Hall sensor, and the voltage regulation accuracy High voltage fluctuation is very small; the time relay has high control precision and the soft time can be adjusted arbitrarily to meet the needs of various electrophoresis occasions.

Product Usage

The electrophoresis power supply is widely used in the surface treatment of daily-use hardware, that is, electrophoretic coating.


(1) The main circuit adopts a three-phase fully-controlled rectifier circuit, and the output end is equipped with an LC filter, with small ripple coefficient and smooth and continuous current;

(2) The main circuit is an imported thyristor element, which has overvoltage, overheating and overcurrent protection functions, which is safe and reliable;

(3) The connection between the rectifier transformer and the rectifier element adopts a compact structure, which makes maintenance simple and convenient;

(4) Control cabinet output voltage stabilization accuracy ≤±1%; output current limit range 20%~100% rated current value;

(5) The output voltage is linear and flexible, and the rise time is adjustable from 0 to 150 seconds;

(6) The thyristor trigger and control circuit is an independent unit, which is convenient and practical;

(7) Local control and remote control can be realized to facilitate the safe isolation of the electrophoresis tank and the electrophoresis power supply;

(8) Three-phase AC input has no phase sequence requirements, installation and wiring are simple and convenient;

(9) adopts anti-salt spray acidification measures to extend the service life of the power supply in harsh environments.
