GAOHUI 12V 50A IGBT Pulse Plating Rectifier for Precision Gold Electroplating

Key Features & Engineering Highlights
Our GAOHUI 12V 50A industrial high frequency rectifier factory direct unit delivers superior current stability for precious metal deposition. This heavy-duty DC power supply price point offers unmatched value for shops requiring tight process control. As a leading IGBT rectifier manufacturer, we integrate high-frequency switching at 20kHz for ripple-free output below 1% RMS, critical for bright gold finishes. The unit supports custom current voltage rectifier configurations for jewelry gold plating and electronic connector finishing. Built with industrial-grade IGBT modules and a digital PID controller, it ensures 0.5% regulation accuracy across all load conditions, eliminating the need for manual adjustments during long production runs.

Advanced Built-in Protection Systems
This rectifier is engineered with multi-layer safety to protect both your investment and your workpieces. Overvoltage protection (OVP) clamps output at 14V to prevent burning delicate gold deposits. Overcurrent protection (OCP) triggers at 55A with automatic shutdown within 100 microseconds. Overtemperature protection uses a dual-thermistor system on the IGBT heatsink and transformer core, engaging a fan boost or total shutdown at 85°C. Short-circuit protection is instantaneous, with no damage to internal components. Input surge protection handles spikes up to 2kV via metal oxide varistors. All protection events are logged in non-volatile memory with a front-panel LED fault indicator.

Target Industrial Applications
This 12V 50A unit is purpose-built for gold plating rectifier applications in jewelry manufacturing, where precise voltage control prevents burning on thin deposits. It excels in rack plating precision for electronic connectors requiring uniform thickness across complex geometries. Use for silver strike plating to improve adhesion on stainless steel or nickel substrates. Ideal for small-scale electrowinning of gold from spent solutions in recycling operations. Also suitable for decorative brass plating and zinc passivation in batch production lines. The pulse function allows fine-tuning for hard gold plating on contact pins to meet MIL-spec wear resistance.

Customization and Tailored Engineering Services
Our factory custom capability spans 1V-1000V and 1A-100,000A with any AC input voltage. For this model, we offer optional modules including a Digital Process Timer for automatic batch termination, Multi-Stage Programmable Profile Control for ramp-up and soak cycles, and an Ampere-Minute Integrator for precise precious metal tracking. Add Automatic Reverse Polarity for periodic reverse plating to reduce stress in gold deposits. The Soft-Start Ramp-Up feature gradually increases current over 0-99 seconds to prevent thermal shock. Choose Local/Remote Control via front-panel Push-Button or a 7-inch HMI Touch Screen with recipe storage. Interface options include RS485 Modbus RTU for PLC integration, Ethernet for remote monitoring, and 4-20mA analog control. Pulse Functions offer 1-100% duty cycle and 1-3000Hz frequency adjustable for optimizing grain structure in gold plating.
