SMPS Power Unit 4000A For Plant Rectifiers

SMPS power unit 4000A for plant rectifiers

 1. Function                                                                                                                             

   Rectifiers are used to convert AC power to DC power for many different applications and plants. It utilises silicon diodes for uncontrolled applications and thyristors(or IGBT etc.) for controlled.

   Rectifiers could be convection cooled, forced-air cooled (using fans), or water-cooled in conjunction with a cooling tower and are usually installed.

   Our rectifiers are for many different applications, such as low voltage high current plating/anodizing, crystal growth heating, melting furnace heating, waste water treatmeng and battery charging etc.
