GAOHUI 30V 5000A IGBT Water Electrolysis Rectifier for Green Hydrogen Production

Part 1: Key Features & Engineering Highlights

* This heavy-duty DC power supply, engineered by a leading IGBT rectifier manufacturer, delivers a stable 30V 5000A output specifically for high-efficiency alkaline water electrolysis and PEM electrolyzer stacks. As a dedicated industrial high frequency rectifier factory, we ensure the power factor on the network side exceeds 99% with total harmonic distortion (THDi) less than 3%, optimizing your custom current voltage rectifier for maximum electrolysis efficiency.
* The core IGBT switching technology provides precise, ripple-free DC power, essential for maintaining uniform current distribution across electrolyzer cells. This directly supports the production of high-purity hydrogen by ensuring consistent electrochemical reaction conditions, a critical factor when evaluating any heavy-duty DC power supply price against performance.
* Our system is designed for seamless integration with AC inputs of 380V, 10kV, and 35kV, offering flexible installation for various industrial scales. The robust structure is built for continuous 24/7 operation, reducing downtime and total cost of ownership for your hydrogen production facility.
* The power supply features a fully integrated digital control system with an RS485 Modbus RTU interface, enabling direct communication with your plant’s DCS or PLC. This allows for real-time monitoring of voltage, current, and temperature, ensuring optimal performance for your electrolysis process.

Part 3: Advanced Built-in Protection Systems

Our GAOHUI rectifier is equipped with comprehensive protection to safeguard your electrolyzer stack and the power supply itself. Standard protections include over-voltage protection (OVP), over-current protection (OCP), short-circuit protection (SCP), over-temperature protection (OTP), and input phase loss detection. The system also features a soft-start ramp-up function to prevent inrush current during startup, protecting both the power supply and the electrolyzer stack from electrical stress. An automatic reverse polarity function is available as a customization to prevent damage from incorrect connection.

Part 4: Target Industrial Applications

This power supply is specifically designed for water electrolysis for green hydrogen production, including both alkaline water electrolysis and PEM electrolyzer stack systems. It is also perfectly suited for other demanding DC processes such as electrowinning of non-ferrous metals (copper, zinc, nickel), electrorefining, and specialized electrochemical processes requiring ultra-stable, high-current DC output.

Part 5: Customization and Tailored Engineering Services

As a factory, we offer extensive customization across a full range of 1V-1000V and 1A-100,000A for AC input / DC output only. We engineer custom functional modules to match your specific process requirements. Options include a Digital Process Timer for batch control, a Multi-Stage Programmable Profile Control for complex current ramping, an Ampere-Minute Integrator for precise charge control, and Automatic Reverse Polarity for periodic reversal. Our control options range from simple Local/Remote Push-Button to full HMI Touch Screen interfaces. For advanced integration, we provide RS485 Modbus RTU, Ethernet, and 4-20mA interfaces, plus Pulse Functions with adjustable duty cycle (1-100%) and frequency (1-3000Hz) for specialized electrochemical applications.
