Advanced Built-in Protection Systems
This custom current voltage rectifier integrates multiple safety layers to safeguard both the equipment and the plasma polishing process. Microsecond-level fault response time ensures immediate shutdown upon overvoltage, overcurrent, overtemperature, or short circuit detection. The GAOHUI system includes input phase loss protection and soft-start circuitry to prevent inrush damage. For electrolytic surface treatment, these protections guarantee uninterrupted operation and extend the lifespan of both the rectifier and the treatment bath.
Target Industrial Applications
This rectifier is engineered for plasma electropolishing and electrolytic surface treatment, including metallic gloss shining and environmentally friendly deburring. It is also ideal for electrowinning, hard anodizing, precious metal plating, and metal ore refining processes that demand precise DC power. The 300V 50A output supports variable power supply configurations for plasma polishing and metal ore refining, making it a versatile choice for surface finishing shops.
Customization and Tailored Engineering Services
As a flexible IGBT rectifier manufacturer, GAOHUI offers full customization from 1V to 1000V and 1A to 100,000A, with AC input options and DC output only. Custom functional modules include a Digital Process Timer for precise cycle control, Multi-Stage Programmable Profile Control for complex polishing sequences, an Ampere-Minute Integrator for charge tracking, Automatic Reverse Polarity for enhanced surface removal, and Soft-Start Ramp-Up to protect workpieces. Control options range from Local/Remote via Push-Button or HMI Touch Screen.
