GAOHUI 12V 300A Precious Metal Plating Rectifier IGBT Power Supply for Electroplating Gold Silver Nickel

Key Features & Engineering Highlights

Our 300A 12V electroplating rectifier power supply delivers precise metal deposition via electrolysis for surface treatment, ensuring uniform coating thickness on precious metals. As a leading IGBT rectifier manufacturer, we utilize advanced Germany technology cooling system to maintain stable output under continuous heavy-duty DC power supply price points. This heavy-duty DC power supply price includes high-frequency switching for low ripple, critical for mirror-finish gold and rhodium plating tank operations. The unit operates in constant current (CC) and constant voltage (CV) modes, providing the exact control required by a custom current voltage rectifier for complex bath chemistries. Designed for efficiency, this industrial high frequency rectifier factory model achieves over 90% energy conversion, reducing operational costs for high-volume plating lines.

Advanced Built-in Protection Systems

This 12V 300A programmable DC reversing power supply is ideal for electroplating gold, silver, nickel, and copper, featuring automatic polarity reversal for complex deposition cycles. The unit includes multi-layer protection: over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP), short-circuit protection, and input phase-loss detection. A soft-start ramp-up function prevents current spikes during initial power-on, safeguarding delicate workpiece surfaces. The industrial high frequency rectifier factory design also incorporates arc suppression for safe disconnection under load. All protection thresholds are field-adjustable via the front panel or remote interface, ensuring compatibility with any laboratory precision rectifier application.

Target Industrial Applications

This electroplating rectifier is engineered for precise metal deposition via electrolysis for surface treatment across diverse shop processes. Primary applications include precious metal plating for gold, silver, platinum, and rhodium tank operations. It also excels in decorative and functional chrome plating, nickel plating, copper plating, and brass plating for jewelry, electronics, and automotive components. For specialized tasks, the unit supports pen plating machine setups for brush plating of gold, silver, brass, nickel, and copper on localized areas. Additional uses include electrowinning for metal recovery, electroforming for intricate molds, and hard anodizing for aluminum alloy components. The low ripple output makes it ideal for laboratory precision rectifier work requiring tight thickness tolerances.
