» Product Description In a 3000A 20V DC rectifier for anodizing & metal finishing, after the AC input voltage is filtered by a rectifier circuit, high-voltage DC power is obtained. The “variable frequency conversion” stage inverts this high-voltage direct current into approximately 30kHz high-frequency alternating current. This high-frequency A
» Product Description The Anodizing Rectifier delivers precise high-voltage control (up to 120V+) for hard anodizing. It supports currents from hundreds to tens of thousands of amps. Unlike decorative processes at 20V–24V, its high-frequency switching slashes oxide layer formation time by 30% and energy use. Compact design ensures s
