This surface treatment rectifier delivers adjustable stable DC for medium‑voltage electrophoresis workflows. It ensures uniform coating film for medium‑size metal parts during continuous production.
The 30A 150V Surface Treatment Rectifier from Gaohui Power Supply converts three‑phase AC into tunable direct current for electrophoresis lines. It is widely adopted for aluminium profiles, automotive hardware and various metal component finishing. Many production workshops suffer uneven coating thickness under medium‑voltage continuous running, and this rectifier mitigates such defects effectively. It maintains consistent deposition quality for both medium‑size batches and high‑volume mass manufacturing.
This surface treatment rectifier supports cathodic and anodic electrophoresis. Its 0‑150V adjustable output meets medium‑voltage process demands that ordinary low‑voltage Power Supply cannot handle. Built‑in IGBT inverter hardware suppresses output drift, even during multi‑day non‑stop operation inside chemical‑laden production workshops.
‑ 0‑150V adjustable DC voltage, 0‑30A adjustable DC current; voltage & current accuracy within one percent ‑ Ultra‑low‑ripple pulse output ≤2% ripple factor, improves coating effect for complex shaped workpieces ‑ Dual constant‑current / constant‑voltage operation with configurable ramp‑up function ‑ Digital Ah meter plus minute‑level programmable timer to support unattended production shifts ‑ Standard RS485 Modbus RTU port for integration with automated coating production lines
This surface treatment rectifier uses mature IGBT topology, bringing Power Supply conversion efficiency above ninety percent. Under 24/7 full‑load operation, heat generation stays low and thermal shutdown risks drop significantly. Forced‑air cooling design also lowers regular maintenance burden for factory operators.
Native automatic polarity reversal streamlines tank cleaning and electrode maintenance work. Operators no longer need to swap wiring manually to reverse polarities. Multi‑segment programming allows users to set multi‑stage voltage‑current curves for sophisticated paint formulas, expanding compatibility with different paint chemistries.
Internal circuits use corrosion‑resistant, anti‑interference components. The rectifier stays stable in humid, chemical‑vapour‑filled workshop environments. It minimises colour deviation and inconsistent film thickness triggered by voltage fluctuation.
