Product Description

380V Three-Phase Input 18V 250A Programmable DC Rectifier

This 18V 250A programmable DC rectifier is designed for heavy-duty industrial applications requiring stable and precise DC output. Powered by a 380V three-phase input, it delivers high efficiency, low ripple, and reliable performance even under continuous operation. The programmable control system allows users to set voltage, current, timing, and protection parameters with ease. Ideal for electroplating, electrolysis, hydrogen production, battery charging, and other demanding processes.
