Overview

  • We manufacture various industrial rectifiers used in electroplating, electrocoating, anodizing, electrolysis, and general DC power supply systems.

  • The rectifier control methods include IVR input type and thyristor (SCR) control type. Among these, the inductive type supplies excitation voltage to the rectifier transformer using an inductive voltage regulator, allowing tap setting control within the regulation range.

  • The thyristor control method includes two configurations: phase control using thyristors on the AC input side with output voltage adjustment through a transformer, and phase control using thyristors on the transformer secondary side. Products are manufactured and supplied according to customer requirements.

Features

Contactless, Continuous Operation

As a contactless and continuous operation system, it is not affected by failures caused by contact wear or poor electrical contacts.

Built-in Constant Voltage and Constant Current Functions for High Stability

When set to constant voltage or constant current mode, automatic control is applied, providing control stability within ±1.5%.

Improved Maintenance Capability

The unitized design allows maintenance from the front side, significantly improving serviceability.

Enhanced Safety and Reliability

All models are equipped with automatic constant voltage and constant current control functions along with comprehensive protection systems, improving overall operational stability and reliability.

Applications

  • Industrial Rectifier
  • Electroplating Rectifier
  • Electrolysis Rectifier
  • Electrophoretic Deposition (EPD) Rectifier
