Heavy-Duty Precious Metal Plating Power Supply (12V 300A) for Jewelry and Industrial DC Rectification

Engineered for the exacting demands of precious metal recovery and deposition, this 12V 300A rectifier is more than a power source—it is the backbone of your plating line. Designed for use with gold, silver, rhodium, and platinum electrolytes, it delivers ripple-free DC output essential for achieving mirror-bright finishes without burning delicate contacts. As a leading industrial high frequency rectifier factory, we build these units to outperform traditional SCR and transformer-based systems, offering greater efficiency and precise control for both gang-run production and custom current voltage rectifier needs.
Part 1 Key Features & Engineering Highlights
High-Frequency Switch Mode Topology: Fully IGBT-based design achieves >90% conversion efficiency, drastically reducing thermal load and electrical noise. This translates to lower operating costs and a compact footprint critical for lab or jewelry bench layouts.
Precision Digital Control with Closed-Loop Feedback: The digital PID controller maintains constant current (CC) and constant voltage (CV) modes with 0.1% accuracy. This stability is crucial for rhodium plating tanks where consistent current density determines the metal’s final wear resistance.
