Our IGBT rectifier boasts industry-leading features that meet strict modern industrial demands. Furthermore, these features help you gain a competitive edge in the market. Below are the core features in detail:
We offer pure DC, single pulse, dual pulse, and reverse pulse modes, which provide the flexibility needed for metal electrolysis, hydrogen production, and wastewater treatment. For instance, reverse pulse prevents scaling in electrodialysis, while pulse mode boosts hydrogen production efficiency. Moreover, our customizable rectifier easily adapts to your unique process needs.
The rectifier features adjustable frequency (10–1000Hz) and duty cycle (0–100%), with output accuracy reaching ≤1%. For high-precision scenarios like copper foil electrolysis, accuracy even hits ≤0.5%. This level of precision not only stabilizes electrochemical reactions but also improves product purity and reduces energy consumption, making our industrial electrolysis power supply a cost-effective choice.
We utilize a three-proof structure (dustproof, waterproof, anti-corrosion) and an industrial-grade housing, which we specifically optimized for humid, corrosive, and high-temperature industrial sites. As a result, the rectifier operates stably in harsh conditions, thereby reducing maintenance costs and ensuring long-term reliability for your production line.
It is equipped with comprehensive protection functions, including phase loss, overheat, overcurrent, short circuit, undervoltage, overvoltage, communication issues, and cooling water abnormalities. These functions effectively prevent equipment damage and ensure safe continuous operation, as our IGBT electrolysis rectifier fully meets international safety standards.
The rectifier supports standard RS485 communication, 4-20mA signal transmission, and remote monitoring, allowing users to control and monitor the device remotely with ease. Additionally, users can adjust output parameters in real time and schedule power, which is particularly suitable for large-scale workshops and distributed hydrogen projects, ultimately boosting production efficiency.
We use high-quality industrial-grade IGBT components and a stable circuit structure, with a modular design that simplifies maintenance and expansion. Thanks to these design choices, the electrolysis power supply has a service life of ≥8 years under normal use, lowering long-term replacement and maintenance costs.
GAOHUI’s industrial electrolysis power supply offers clear advantages over competitors, which help enterprises reduce costs and enhance productivity significantly.
It ensures stable current and voltage with ripple ≤1%, which avoids defects caused by power fluctuations—such as uneven metal plating and low hydrogen purity.
This stability improves product qualification rates and reduces material waste, making our IGBT electrolysis rectifier a trusted choice for global customers.
The rectifier adopts advanced IGBT high-frequency switching technology and an optimized circuit design, achieving an overall efficiency of ≥95% (≥97% for hydrogen electrolysis rectifiers).
Over time, this energy-saving structure saves considerable electricity costs during long-term continuous operation, especially for high-power scenarios like aluminum smelting.
It features a user-friendly PLC touch screen and automatic control functions, supporting one-click parameter setting, fault self-diagnosis, and data recording.
Even new operators can master the system quickly, which reduces training time and labor costs, as our customizable electrolysis rectifier prioritizes user-friendliness.
We provide tailored solutions for different processes and scenarios, adjusting current, voltage, output mode, cooling method, and control functions to match your specific needs.

Our electrolysis rectifier is widely used across various industries, covering nearly all industrial electrolysis processes. Moreover, it has become an essential power device for large-scale production lines globally. Specifically, its specific applications include the following key areas:
First and foremost, it is extensively used in aluminum, copper, zinc, nickel, and rare earth electrolysis, as it provides stable high-current power to support these critical processes. Consequently, this stability ensures metal purity and production efficiency, thereby making our high current electrolysis rectifier the top choice for metal smelters worldwide.
In addition to metal smelting, the rectifier also supports water electrolysis, solar hydrogen, and green hydrogen projects. Notably, it features wide-range power adjustment to adapt to the volatility of renewable energy, which in turn ensures high hydrogen purity and production efficiency. Furthermore, it supports the "double carbon" strategy, making our hydrogen electrolysis rectifier a key component for green hydrogen production.
Another important application lies in wastewater and environmental protection treatment. Specifically, it is suitable for industrial wastewater electrolysis, electrocoagulation, electroflocculation, and electrodialysis, as it can effectively remove heavy metals and organic pollutants. Additionally, it enables seawater desalination and meets environmental protection requirements, thus helping enterprises achieve green production goals with our wastewater electrolysis rectifier.
Moving on to the chemical industry, it is widely used in chlor-alkali, caustic soda, and hypochlorite generation processes. By providing stable high-power DC output, it ensures smooth chemical reactions, which ultimately improves product quality. As such, our IGBT electrolysis rectifier is specifically designed to meet the needs of the chemical industry.
Besides industrial production, it is also applied to electrolytic polishing of stainless steel, copper, aluminum, and other workpieces. Importantly, it ensures uniform surface brightness and prevents over-corrosion, which in turn boosts the added value of industrial products. For this reason, our electrolysis power supply provides stable, reliable power for surface treatment processes.
Finally, we can modify the rectifier for special setups, including distributed hydrogen production coupled with solar/wind power and large-scale metal smelting integrated systems. Thanks to its flexible design, our customizable electrolysis rectifier adapts smoothly to unique processes, thereby ensuring optimal performance for your specific production needs.
