Electrophoresis power supply, also referred to as electrophoresis rectifier, converts alternating current into stable direct current to enable uniform deposition of electrophoretic coatings on metal surfaces. Targeting industry pain points such as unstable output, insufficient precision and limited automation, we have developed IGBT-based electrophoresis rectifiers tailored for industrial electrophoretic coating production. These power solutions are widely applied to cathode/anode electrophoretic painting for automotive bodies, hardware, home appliances, aerospace components and architectural metal profiles, delivering consistent coating quality and reliable performance for continuous surface treatment lines.
The electrophoresis rectifier plays distinct yet critical roles across different scenarios, ensuring optimal performance in every use case:

GAOHUI’s electrophoresis rectifier integrates advanced technology and user-centric design to stand out in the market. Below, we break down its core features, starting with the most essential one:
We use IGBT technology to achieve ≤1% accuracy and ripple, which reduces background noise, avoids blurred bands, and ensures consistent, repeatable results for both experiments and production. Moreover, this high precision directly translates to more reliable data in lab settings and fewer defects in industrial production.
The product features an LCD touch screen for one-click parameter setup and real-time data display. It can store up to 100 programs (20 steps each) for quick recall, while stackable lab models save valuable space and remote monitoring via RS485 adds convenience. Additionally, the intuitive interface means even new users can operate the equipment with minimal training.
We’ve equipped the rectifier with multiple protection functions—including no-load, overheat, short circuit, and undervoltage protection—to prevent equipment damage and ensure operator safety during use. Importantly, these protection mechanisms activate automatically, minimizing the risk of accidents and equipment failure.
Lab models use flame-retardant materials for compact, space-saving design, while industrial models feature a dustproof, waterproof, and anticorrosive structure. Both types offer a ≥8-year lifespan and support 24/7 operation. For example, industrial models are specifically engineered to withstand harsh factory environments, ensuring long-term reliability.
