This high‑output electrophoresis rectifier delivers robust adjustable DC for demanding coating workflows. Furthermore, it maintains steady performance under combined high‑current and high‑voltage continuous operation.
Gaohui Power Supply develops the 300A 400V High‑Output Electrophoresis Rectifier for heavy‑duty electrophoresis production plants. To start with, many large‑size workpiece projects demand both ample amperage and elevated voltage to achieve qualified thick protective films, yet ordinary rectifiers cannot satisfy such dual‑demanding process conditions. Because simultaneous high‑current and high‑voltage operation easily triggers output drift and defective coating layers, this Power Supply tightly stabilises voltage and current values to prevent such production failures. What is more, it runs smoothly for round‑the‑clock mass production as well as special‑job custom batches.
This high‑output electrophoresis rectifier supports cathodic plus anodic electrophoresis processing. Apart from that, its broad 0‑400V adjustment scope meets strict technical standards for oversized structural metal pieces. Meanwhile, upgraded reinforced IGBT modules keep stable output even when workshops carry out long‑time heavy‑load runs amid corrosive chemical fume environments.
‑ 0‑400V 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%, delivers homogeneous coating for large‑sized parts with complex geometries
‑ Dual constant‑current and constant‑voltage working modes, supports flexible ramp‑up rate fine‑tuning
‑ Integrated digital Ah counter and minute‑based programmable timer to support unattended multi‑shift plant operation
‑ RS485 Modbus RTU communication port, enables site personnel to link the device directly to factory‑wide automation platforms
We engineer this high‑output electrophoresis rectifier with heavy‑duty IGBT power topology, so it reaches Power Supply conversion efficiency above ninety percent. Even when it outputs full‑rated 300A under 400V for extended working hours, it keeps heat generation under effective control and lowers risks of unexpected thermal shutdown. In addition, forced‑air cooling structure cuts daily maintenance burdens for on‑site technicians.
Its native automatic polarity reversal helps operators simplify tank cleaning and electrode maintenance routines. As a result, workers do not need to rewire hardware manually every time they toggle process polarity. Besides, multi‑segment programming allows users to set multi‑stage voltage‑current profiles; users can match complex high‑voltage coating recipes and broaden compatibility for diverse paint formulations.
Our technical team fits internal circuits with anti‑corrosion and anti‑interference electronic components. Accordingly, the rectifier retains trustworthy output inside humid production spaces filled with chemical vapours. It greatly reduces colour deviation and uneven film thickness caused by external electrical disturbance.

This high‑output electrophoresis rectifier suits high‑power metal finishing tasks that combine high voltage and high current. Above all, it serves oversized structural components, heavy‑duty machinery parts and large‑capacity loading racks requiring thick anti‑corrosion coating layers.
Additionally, production crews deploy this equipment on production lines processing bulky single‑piece workpieces or mixed high‑density part batches. Manufacturing plants opt for this model whenever standard‑spec power units cannot reach required high‑power process thresholds.
It works well with epoxy, acrylic and polyurethane electrophoresis paints for both cathodic and anodic treatment workflows. Thanks to its steady 300A output, it achieves complete and even coating coverage for extra‑large components. Likewise, it delivers solid performance for new‑formula testing batches and non‑stop high‑volume assembly‑line production.
Gaohui Power Supply creates custom‑tailored High‑Output Electrophoresis Rectifier for heavy‑power surface‑treatment manufacturers, and bespoke modification capability forms our key market advantage. First of all, our engineering crew revises output parameters, pulse characteristics, cabinet dimensions and control logic to fit your actual on‑site production realities.
