This heavy‑current electrophoresis rectifier delivers powerful adjustable DC for mass‑production finishing lines. Furthermore, it sustains stable coating output under continuous high‑current heavy‑duty operating cycles.
Gaohui Power Supply builds the 300A 200V Heavy‑Current Electrophoresis Rectifier for high‑output electrophoresis production facilities. To start with, large‑scale finishing lines require substantial electric current to process densely filled workpiece racks, yet conventional medium‑current equipment cannot handle such heavy operating loads. Because extreme current draw will bring output swings and uneven film buildup, this Power Supply firmly locks voltage‑current parameters to avoid those manufacturing flaws. What is more, it delivers steady performance both for round‑the‑clock mass runs and flexible small‑to‑medium batch jobs.
This heavy‑current electrophoresis rectifier supports cathodic alongside anodic electrophoresis workflows. Apart from that, its 0‑200V adjustable output meets medium‑high‑voltage process criteria for high‑volume metal components. Meanwhile, reinforced IGBT hardware maintains consistent performance even as facilities run extended high‑current loads within environments filled with corrosive chemical vapours.
‑ 0‑200V adjustable DC voltage, 0‑300A adjustable DC current; voltage and current regulation accuracy within one percent
‑ Ultra‑low‑ripple pulse output with ripple factor ≤2%, produces consistent coating finishes on densely‑loaded, complex‑contour workpieces
‑ Dual constant‑current and constant‑voltage operation modes, enables flexible ramp‑up speed fine‑tuning
‑ Integrated digital Ah counter plus minute‑level programmable timer to support hands‑free multi‑shift factory production
‑ RS485 Modbus RTU communication port, allows operators to connect this hardware directly to plant‑wide factory automation platforms
We engineer this heavy‑current electrophoresis rectifier around robust IGBT power topology, so it achieves Power Supply conversion efficiency higher than ninety percent. Even while putting out its full‑rated 300A across long operating hours, it keeps heat output well‑managed and lowers risks of unplanned thermal shutdown. In addition, forced‑air cooling eases daily maintenance assignments for on‑site plant operators.
Its built‑in automatic polarity reversal lets personnel simplify bath cleaning and electrode upkeep tasks. As a result, operators no longer have to rewire physical hardware manually each time they flip process polarity. Besides, multi‑segment programming empowers users to configure multi‑stage voltage‑current profiles; users can adapt to various high‑throughput coating recipes and expand compatibility across different paint chemistries.
Our technical team outfits internal circuits with corrosion‑resistant, anti‑interference electronic parts. Accordingly, the rectifier preserves dependable output inside humid workshops saturated with chemical fumes. It greatly minimises colour shifts and inconsistent film thickness triggered by outside electrical interference.

Furthermore, timed operating cycles and multi‑segment profiles accommodate heavy‑duty, high‑density coating production tasks. The hardware ships complete with RS485 interface and automatic polarity reversal. Feel free to reach out and share your custom Power Supply requirements.
This heavy‑current electrophoresis rectifier fits high‑current, medium‑high‑volume metal finishing operations. Above all, it caters for high‑throughput automotive assemblies, large aluminium extrusions and densely stacked metal batches needing reliable anti‑corrosion protective layers.
Additionally, production crews deploy this unit on assembly lines running fully populated workpiece racks inside large finishing plants. Manufacturing facilities select this model whenever mid‑current rectifiers fail to deliver sufficient amperage under high‑density loading scenarios.
It pairs well with epoxy, acrylic and polyurethane electrophoresis paints for both cathodic and anodic processing. Thanks to its stable 300A output, it achieves complete, uniform coating coverage over heavily‑filled workpiece racks. Likewise, it delivers trustworthy performance for formula test batches as well as non‑stop high‑volume assembly‑line manufacturing.
