12V 500A Air Cooled Rectifier for Electroplating Line

Lyhaina — Mon, 25 May 2026 03:12:10 +0000

» Product Description

The critical DC output stability is achieved through a multi-stage conversion process. This high-performance system is a 1500A, 12V air-cooled rectifier, designed specifically for PCB plating applications. After the AC input voltage is filtered by a rectifier circuit, high-voltage DC power is obtained. The “variable frequency conversion” stage inverts this high-voltage direct current into approximately 30kHz high-frequency alternating current. This high-frequency AC is then transformed into secondary voltage via a high-frequency transformer and filtered through a high-frequency rectifier circuit to produce the required output voltage. The Rectifier for Plating employs a control circuit to sample output voltage and current. These sampled signals undergo closed-loop feedback to generate pulse width modulation (PWM) signals, which regulate the inverter circuit and maintain stable output voltage/current – a critical requirement for precision electroplating applications.

» Product Applications

The rectifier is mainly used in industries such as electrolytic gas, electrolytic hydrogen production, electrolytic copper foil, electronic aluminum foil, rare earth smelting, PCB electronics, hardware electroplating, oxidation, water treatment, etc.

› High power factor and high efficiency

› Reasonable structural design

› Only the radiator is in the air duct

› Effective sealing and isolation

› High protective properties

› Standard wiring and special wiring

› Practical and effective multiple protection system

› Full soft switching technology

› High reliability

» Role of electroplating

› Copper Plating

Primarily applied to improve substrate adhesion for subsequent plating layers while enhancing corrosion resistance. Requires protective topcoats due to oxidation concerns—unprotected copper forms non-conductive patina over time.

› Nickel Plating

Serves as a functional base layer or decorative finish, offering excellent corrosion and wear resistance. Electroless nickel variants approach chrome-level durability. Note: Magnetic properties restrict usage in sensitive electronic components (e.g., RF connectors) where signal interference must be avoided.

› Gold Plating

Preferred for critical electrical contacts where stable impedance and optimal signal transmission are essential. Though highly reliable, material costs limit large-scale applications.

› Palladium-Nickel Plating

Superior wear resistance and signal stability vs. gold plating. Combines palladium’s oxidation resistance with nickel’s structural integrity for high-cycle connectors.

› Tin-Lead Plating

Historically favored for solderability enhancement. Now largely discontinued due to RoHS regulations; modern replacements include pure matte or bright tin formulations.

› Silver Plating

Delivers maximum electrical conductivity and signal performance across high-frequency applications. Maintains functionality when oxidized but requires anti-tarnish treatments due to surface darkening. Premium cost reflects performance advantages.

› Selection Considerations

Specify plating type according to: Required corrosion/wear resistance thresholds Electrical performance parameters Budgetary constraints Environmental compliance requirements Long-term maintenance considerations

» Elements of Electroplating

› Cathode

The object to be plated (e.g., connector terminals or metal surfaces) where metal ions deposit into a solid coating.

› Anode

Soluble Anode: Made of the plating metal. Dissolves during electrolysis to replenish metal ions in the solution. Insoluble Anode: Used for precious metals (e.g., white gold, iridium oxide). Does not dissolve but supplies electrons for reduction.

› Plating Solution

Contains ions of the target metal. Composition and concentration determine coating thickness, adhesion, and appearance.

› Plating Tank

Materials: Must resist corrosion and temperature fluctuations (e.g., polypropylene, titanium alloys). Role: Stores solution and maintains stable plating conditions.

› Rectifier

Converts AC to DC power to drive electrolysis. Adjust voltage/current to control deposition speed and coating thickness.

› Auxiliary Equipment

Filters: Remove impurities from the solution. Heaters: Maintain solution temperature. Stirrers: Ensure uniform mixing.

12V 400A Rectifier for Industrial Nickel Electroplating

Lyhaina — Tue, 23 Dec 2025 01:38:24 +0000

» Product Description

In a 12V 400A rectifier for industrial nickel electroplating, the AC input voltage is first converted to a pulsating DC voltage by a rectifier circuit. This pulsating DC is then filtered to produce a smooth DC output. The “variable frequency conversion” stage inverts this high-voltage direct current into approximately 30kHz high-frequency alternating current. This high-frequency AC is then transformed into secondary voltage via a high-frequency transformer and filtered through a high-frequency rectifier circuit to produce the required output voltage. The Electroplating Rectifier Power Supply employs a control circuit to sample output voltage and current. These sampled signals undergo closed-loop feedback to generate pulse width modulation (PWM) signals, which regulate the inverter circuit and maintain stable output voltage/current – a critical requirement for precision electroplating applications.

5V 300A Nickel Plating Rectifier Power Supply

Lyhaina — Sun, 15 Jun 2025 06:24:19 +0000

» Product Description

In a 5V 300A nickel plating rectifier power supply, after the AC input voltage is filtered by a rectifier circuit, high-voltage DC power is obtained. The “variable frequency conversion” stage inverts this high-voltage direct current into approximately 30kHz high-frequency alternating current. This high-frequency AC is then transformed into secondary voltage via a high-frequency transformer and filtered through a high-frequency rectifier circuit to produce the required output voltage. The nickel plating rectifier power supply employs a control circuit to sample output voltage and current. These sampled signals undergo closed-loop feedback to generate pulse width modulation (PWM) signals, which regulate the inverter circuit and maintain stable output voltage/current – a critical requirement for precision electroplating applications.

» Product Applications

Plating rectifiers support surface treatments like PCB electroplating, hard chrome coating, and metal plating (Cu, Ni, Zn, Au, Ag).

» Role of electroplating

Protection Against Corrosion

– Shields metal surfaces from rust and chemical damage (e.g., zinc plating on steel).

Increased Wear Resistance

– Hard coatings (e.g., chromium plating) reduce friction and extend part life.

Improved Appearance

– Adds shiny, decorative finishes (e.g., gold plating on jewelry, chrome on car parts).

Better Electrical Conductivity

– Used in electronics (e.g., copper plating on circuit boards).

Enhanced Solderability

– Improves bonding in electronic components (e.g., tin plating).

Repair of Worn Parts

– Restores dimensions and functionality (e.g., rebuilding engine components).

Special Industrial Uses

– Provides heat resistance (e.g., nickel plating in aerospace).

– Used in medical devices (e.g., biocompatible coatings).

» Types of electroplating

› Copper Plating

Purpose: Enhances adhesion for subsequent layers and corrosion resistance.

Note: Prone to oxidation (forms non-conductive copper oxide/green patina). Requires protective coatings.

› Nickel Plating

Purpose: Used as a base layer or decorative finish; improves corrosion/wear resistance. Electroless nickel offers chrome-like durability.

Note: Magnetic properties limit use in electronics (e.g., DIN/N connectors) to avoid signal interference.

› Gold Plating

Purpose: Optimizes conductive contact impedance and signal transmission.

Key: High stability but costly.

› Palladium-Nickel Plating

Purpose: Superior signal transmission and wear resistance vs. gold.

Advantage: Combines palladium’s corrosion resistance with nickel’s hardness.

› Tin-Lead Plating

Purpose: Improves solderability.

Trend: Phased out due to lead concerns; replaced by bright/matte tin alternatives.

› Silver Plating

Purpose: Best conductivity and signal performance.

Note: Conducts even when oxidized but tarnishes over time. Higher cost.

Selection Criteria

Match plating type to application needs: corrosion/wear resistance, conductivity, cost, and environmental regulations.
