GAOHUI 18V 2000A Industrial Hard Chrome Plating IGBT Rectifier with Microsecond Protection

Key Features and Engineering Highlights
The GAOHUI 18V 2000A IGBT rectifier is engineered for heavy-duty DC power supply price performance, delivering precise 0-2000A adjustable output for high-speed chrome plating. As a leading IGBT rectifier manufacturer, we integrate advanced PWM technology to ensure a pure three-phase waveform free of voltage spikes, critical for hard chrome adhesion. This custom current voltage rectifier achieves over 90% efficiency, reducing operational costs for any industrial high frequency rectifier factory. The digital meter displays current accurate to 1A, enabling tight process control for automotive parts finishing.

Advanced Built-in Protection Systems
This 18V 2000A plating rectifier includes comprehensive safeguards for continuous operation in harsh environments. It features overvoltage, overcurrent, and short circuit protection with microsecond-level fault response time, preventing damage to both the rectifier and the workpiece. Overtemperature protection automatically reduces output or shuts down the unit if internal heat exceeds safe limits. Input phase loss and under-voltage protection ensure stable operation even with fluctuating mains power, a key requirement for any heavy-duty DC power supply price segment.

Target Industrial Applications
This rectifier is specifically designed for decorative chrome and high-speed chrome plating lines, delivering the precise voltage and current needed for bright, adherent deposits. It is ideal for electrowinning of chromium from solutions, hard anodizing of aluminum components, and precious plating of gold or silver in high-volume shops. The unit excels in automotive parts finishing, where consistent layer thickness and defect-free surfaces are mandatory.

Customization and Tailored Engineering Services
GAOHUI offers full factory custom capability for this rectifier, with a range of 1V-1000V and 1A-100,000A, input from AC to output DC only. We can integrate custom functional modules including a Digital Process Timer for batch control, Multi-Stage Programmable Profile Control for complex plating cycles, an Ampere-Minute Integrator for precise deposit thickness, and Automatic Reverse Polarity for improved surface finish. Soft-Start Ramp-Up prevents current surges on delicate parts. Local and remote control options include push-button panels or HMI Touch Screen interfaces. Communication interfaces such as RS485 Modbus RTU, Ethernet, and 4-20mA analog control are available for integration with factory automation systems. Additionally, pulse functions with 1-100% duty cycle and 1-3000Hz frequency adjustable can be added for advanced plating applications like pulse chrome.
