GAOHUI 12V 2500A IGBT Rectifier | High-Efficiency DC Power Supply for Industrial Tin Plating

This heavy-duty electroplating rectifier is purpose-built to meet the demanding requirements of continuous tin plating lines, delivering stable 12V output at 2500A with precise voltage and current regulation. As a trusted industrial high frequency rectifier factory, GAOHUI engineers this system to reduce energy waste while maximizing deposition consistency across large surface areas. The unit is designed for 24/7 production environments, offering direct replacement for older SCR-based units with a significant reduction in ripple and thermal load.

Part 1: Core Performance & Design Highlights
– High-frequency IGBT switching technology achieving over 90% efficiency at full load, minimizing operating costs for high-current tin plating operations.
– Closed-loop constant current and constant voltage control with 0.5% regulation accuracy, ensuring uniform tin coating thickness across complex part geometries.
– Advanced air-cooled thermal management system rated for ambient temperatures up to 45°C, eliminating water cooling infrastructure requirements and reducing maintenance.
– Modular power stage design enabling easy field expansion or redundancy, with N+1 configuration available for mission-critical production lines.
– Built-in soft-start circuitry and comprehensive fault protection including overcurrent, overvoltage, overtemperature, and phase loss detection.

Part 3: Industrial Fields & Tailored System Features
This rectifier is optimized for tin plating applications including bright tin, matte tin, and reflow processes in PCB manufacturing, electronic component finishing, and semiconductor lead frame plating. The system supports multi-stage current profiles that can be programmed via the front panel touchscreen or remote HMI, enabling precise control of strike, plating, and rinse cycles. For advanced process control, the IGBT rectifier manufacturer integrates automatic polarity reversal capability to eliminate burning at high current densities, as well as microsecond-level fault response time that protects both the work piece and the power supply. The unit can be configured with optional pulse modulation functions for specialized tin alloy deposition requirements. When sourcing a heavy-duty DC power supply price, this model includes remote monitoring and data logging as standard, allowing integration into factory-wide MES systems. As a custom current voltage rectifier, GAOHUI offers modifications such as extended output cable lengths, specialized bus bar configurations, and enclosure ratings up to IP54 for harsh plating environments.
