oxidation rectifier power supply

Product Overview: The oxidation rectifier power supply is a DC power supply device specifically designed for anodic oxidation processes on metal surfaces. Its primary function is to convert three-phase AC power into adjustable DC voltage and current, providing a stable anodic oxidation current to aluminum, magnesium, titanium, and other metal workpieces in the oxidation bath. Its operating principle is as follows: After being isolated and stepped down by a rectifying transformer, the AC power is rectified into an adjustable DC output using thyristors or high-frequency switching devices. A closed-loop current- or voltage-regulation control ensures uniform and dense oxide film growth. The core requirements of the anodizing process for the power supply are current stability and controllable output waveform. The typical anodizing current density is 1.
