Industrial Plating Rectifiers - DNS POWER SYSTEMS

High-Precision Plating & Electrolysis Technology

High-Current Industrial Plating Rectifier Systems

DNS Power Systems manufactures heavy-duty, high-precision Plating Rectifiers specifically engineered for advanced surface finishing, electroplating, anodizing, and electrolysis processes. Utilizing cutting-edge Switch-Mode (IGBT) or Thyristor (SCR) topologies, our industrial-grade power supplies convert alternating current (AC) from the main grid into a highly stable, high-amperage direct current (DC) required for optimal electrochemical deposition.

Our rectifiers deliver ultra-stable DC output with low ripple voltage, ensuring exceptional coating uniformity, precise thickness control, and brilliant finishing quality while maximizing overall grid energy efficiency.

Engineered for Harsh Electrochemical Environments

Built to withstand the extremely harsh, corrosive, and humid environments of chemical plating shops, these high-amperage systems feature robust environmental sealing and smart thermal protection mechanisms for continuous, 24/7 heavy-duty operations. To ensure seamless automation integration, DNS rectifiers are equipped with comprehensive remote control and monitoring options, including RS485, Modbus, and standard PLC interfaces, allowing operators to control voltage and current precision with absolute accuracy.

Usage Areas

These systems are widely used in heavy industries where high-current surface treatments and electrochemical processes are required:

Electroplating (Galvanization) Plants: For coating steel, iron, or other metals with zinc, nickel, copper, chrome, gold, or silver to prevent corrosion and extend product lifespan.

Automotive and Aerospace Industries: For hard chrome plating of wear-resistant components like engine parts, hydraulic shafts, and aircraft landing gears.

Electronics and PCB (Printed Circuit Board) Manufacturing: For precise, uniform copper, nickel, or gold plating on the micro-tracks of electronic circuit boards used in smartphones, computers, and medical devices.

Aluminum Anodizing Plants: For creating a protective and decorative oxide layer on architectural profiles, defense industry parts, and consumer cookware.

Heavy Electrochemistry and Electrolysis: Used in hydrogen production (water electrolysis), copper foil manufacturing, chlor-alkali industries, and metal refining/electrowinning.

The differences between traditional & Modern Rectifier systems.

DNS Power Systems has two types of technologies SCR (Thrystor based) systems to high-efficiency, modern IGBT (Switch Mode).
