This high‑current coating rectifier delivers stable high‑voltage DC output for heavy‑duty electrophoresis tasks. It achieves consistent film thickness for large‑size workpieces under long‑cycle production.
The 30A 400V High‑Current Coating Rectifier from Gaohui Power Supply converts three‑phase AC input into regulated high‑voltage DC, and it targets demanding electrophoresis production lines. To begin with, many large‑component finishing operations require higher driving voltage to form complete protective coatings, yet ordinary medium‑range equipment cannot handle this work. Since heavy‑load conditions often trigger voltage fluctuation and patchy coating, this Power Supply tightly locks output parameters to remove such defects. Moreover, it runs reliably for intermittent batch jobs as well as non‑stop round‑the‑clock factory shifts.
This high‑current coating rectifier supports both cathodic and anodic electrophoresis processes. Apart from that, its 0‑400V broad adjustment range meets high‑voltage process demands for oversized metal parts. Meanwhile, the IGBT inverter hardware sustains steady performance even when workshops run heavy‑load operations amid chemically aggressive fumes.
‑ 0‑400V adjustable DC voltage, 0‑30A adjustable DC current; voltage and current regulation accuracy within one percent
‑ Ultra‑low‑ripple pulse output with ripple factor ≤2%, delivers smooth finish on large, complex contoured workpieces
‑ Dual constant‑current and constant‑voltage modes, equipped with flexible ramp‑up adjustment
‑ Integrated digital Ah counter and minute‑level programmable timer to support unattended long‑time production
‑ RS485 Modbus RTU communication port, lets operators connect the unit easily with factory automated control systems
We build this high‑current coating rectifier around proven IGBT topology, so it pushes Power Supply conversion efficiency above ninety percent. Even when it runs continuously under full‑current status, it keeps heat output reasonable and cuts risks for unexpected thermal shutdown. In addition, the forced‑air cooling layout helps on‑site operators reduce daily maintenance work.
The on‑board automatic polarity reversal helps operators simplify routine electrophoresis bath cleaning and electrode maintenance work. As a result, operators no longer need to manually swap wiring whenever they switch polarities. Besides, multi‑segment programming lets users set multi‑stage voltage‑current profiles; users can match various sophisticated high‑voltage coating formulas and expand paint‑system compatibility.
Engineers fit internal circuits with corrosion‑resistant and anti‑interference electronic components. Accordingly, the rectifier maintains dependable output even inside damp workshops filled with chemical vapour. It effectively cuts colour deviation and uneven film thickness that external voltage interference brings.

This high‑current coating rectifier targets high‑voltage heavy‑load electrophoresis finishing scenarios. Above all, it serves extra‑large automotive structural pieces, oversized aluminium profiles and bulky metal workpieces that need thick anti‑corrosion protective coating.
Additionally, production teams deploy it widely on lines for large architectural aluminium assemblies and heavy stamped metal components. Factories select this model whenever standard low‑and‑medium‑voltage rectifiers cannot hit required process voltage thresholds.
It works with epoxy, acrylic and polyurethane electrophoresis paints for cathodic and anodic techniques. Thanks to its stable 30A output, it delivers full and uniform coating coverage for big‑size components. Likewise, it performs equally well for small‑batch trial tests and continuous high‑volume assembly‑line manufacturing.
