Introduction to Low-Voltage High-Current Rectifiers

Low-voltage high-current rectifiers are core power conversion equipment in the metal surface treatment industry, specifically designed for electrochemical processes such as electroplating, anodizing, and electropolishing. They accurately convert 380V/220V industrial frequency AC power into 0-36V adjustable DC power, focusing on stable high-current output to meet a wider range of surface treatment process requirements. They enable efficient, precise, and standardized metal surface modification, serving as a crucial link between electrical energy and process results. 1. Core Technical Parameters and Process Adaptability As specialized equipment for metal surface treatment, its parameter design is deeply matched to industry process requirements, and core indicators can be flexibly customized: the output voltage range is continuously adjustable from 0-36V, and the current covers 100A-30000A, broadening the process adaptability. It can meet the needs of micro-plating of precision electronic components and also adapt to scenarios requiring higher voltages, such as galvanizing of large steel parts and thick-film anodizing; the conversion efficiency can reach over 93% at 50-80% load rate, and the power factor is ≥0.95, significantly reducing grid harmonic pollution and energy consumption costs. Optimized design for different process characteristics, the 0-36V wide-range adjustable voltage further enhances adaptability: decorative electroplating requires a soft start function to avoid edge burning caused by surge current; precision electroplating scenarios support high-frequency pulse output (20-50kHz), with current density accuracy reaching ±2mA/cm², suitable for PCB micro-hole copper plating and precious metal micro-plating; in hard anodizing and thick-film anodizing processes, the 36V upper limit voltage can meet the needs of high film thickness growth, and dedicated models are equipped with stepped current control, completing current gradient adjustment within 30 seconds, significantly improving the hardness, density, and thickness uniformity of the oxide film. 2. Typical Application Scenarios and Process Value The equipment is widely applicable to all types of metal surface treatment processes, providing customized power solutions for various industries. Core application scenarios include: 1、Electroplating processes: covering scenarios such as chrome plating of bathroom hardware, nickel plating of automobile wheels, and gold and silver plating of electronic components. In continuous strip galvanizing production lines, the system can respond to strip speed changes within 0.5 seconds, controlling zinc layer thickness deviation to within ±1.5 g/m², supporting high-speed production at 180 m/min; in precious metal electroplating applications, current stability reaches ±0.1%, and gold layer thickness fluctuation is <0.05 μm, significantly reducing precious metal loss. 2、Anodizing: Designed specifically for hard anodizing and thick film anodizing of aluminum, titanium alloys, etc., the 0-36V wide voltage range adapts to different film thickness requirements, providing a high current density of 100 A/dm². The resulting oxide film hardness reaches over 400 HV, and the film thickness range can be extended to 50-150 μm, suitable for products with extremely high requirements for wear resistance, corrosion resistance, and film thickness, such as aerospace components, engineering machinery parts, and smartphone casings, shortening anodizing time by 40% compared to traditional equipment. 3、Electrolytic Polishing and Electrophoretic Coating: In electrolytic polishing, precise current control achieves microscopic leveling of the workpiece surface, improving surface finish; during electrophoretic coating, a stable electric field is provided to ensure uniform deposition of coating particles, enhancing coating adhesion and corrosion resistance, suitable for mass production needs of automotive parts, building profiles, etc. 3. Core Competitive Advantages Compared with traditional rectifier equipment, low-voltage high-current rectifiers have significant advantages in metal surface treatment applications: 1、 Precise temperature control and current distribution design, with a temperature difference of <15℃ between components on the same bridge arm, avoiding equipment failure caused by local overheating and extending service life; 2、 High degree of intelligence, supporting MODBUS communication protocol and MES system integration, enabling remote monitoring and automatic adjustment of process parameters, achieving production line linkage; 3、 Outstanding energy-saving and environmental protection characteristics, the twelve-pulse rectification system reduces grid harmonic content from 30% to 8%, and synchronous rectification technology saves 15-30% energy compared to traditional models; 4、 Complete redundancy design, supporting N+1 parallel backup and online hot maintenance, significantly reducing the risk of production downtime.
