Application Industry: Mainly used in Precious Metal Plating, High precision electrolytic polishing and other industries.
Designed specifically for demanding applications like Precious Metal Plating and High Precision Electrolytic Polishing, this 12V 50A linear power supply low ripple delivers the exceptionally clean, stable power essential for flawless results. Its core strength lies in delivering very low current ripple, ensuring process consistency where even minor fluctuations are unacceptable. Engineered for high reliability, the unit features a robust yet practical structural design incorporating full soft switching technology.
Beyond pure performance, the design prioritizes durability and integration. Effective sealing and isolation provide high protective properties against environmental factors. An optimized cooling system ensures only the radiator is exposed in the air duct, maximizing efficiency while protecting internals. The practical and effective multiple protection system safeguards both the supply and your process. Flexibility is offered through standard and special wiring options, while RS485 digital control enables seamless remote monitoring and system integration. This power supply is built for dependable operation in the most exacting industrial environments.
Mainly used in the precious metal plating industry (including gold plating, silver plating, and jewelry plating), high-precision electrolytic polishing processes (commonly applied to stainless steel), and various other metal finishing applications.

Stops Rust & Chemical Damage
Zinc plating on steel parts creates a barrier against corrosion.
Reduces Wear & Tear
Hard chrome plating cuts friction, making components last longer.
Looks Matter Too
Gold finishes for jewelry / Chrome for car trim – it’s about aesthetics.
Keeps Current Flowing
We plate copper onto circuit boards because it conducts electricity best.
Better Solder Joints
Tin plating helps electronics components bond properly during assembly.
Fix Worn-Out Parts
Rebuild engine crankshafts or bearings by adding new plating material.
Specialized Solutions
Aerospace needs nickel plating: handles extreme heat.
Medical implants use biocompatible coatings so bodies don’t reject them.
Copper Plating
Primarily for base layers – boosts corrosion resistance and helps subsequent coatings stick better.
Watch for: Oxidation (forms non-conductive patina). Always needs a topcoat.
Nickel Plating
Works as a base layer or decorative finish. Fights corrosion/wear – electroless nickel rivals chrome durability.
Heads-up: Magnetic nature messes with electronics (e.g., DIN connectors). Avoid in signal-critical areas.
Gold Plating
King of contact surfaces: Optimizes conductivity and signal clarity.
Stable performance; High cost
Palladium-Nickel Plating
Outperforms gold: Better signal transmission + extreme wear resistance.
Why it wins: Palladium’s anti-corrosion + nickel’s hardness.
Tin-Lead Plating
Was the solderability champ, now phased out (lead regulations).
Switched to: Bright/matte tin alternatives.
Silver Plating
Unbeatable conductivity/signal quality – still works when oxidized.
Downsides: Tarnishes without maintenance; premium pricing.
› Cathode
The object to be plated (e.g., connector terminals or metal surfaces) where metal ions deposit into a solid coating.
› Electroplating Anodes Explained
Soluble Anodes
• Material: Matching plating metal (e.g., copper anodes for copper baths)
• Function: Dissolves to maintain metal ion concentration
• Key use: Standard plating operations
Insoluble Anodes
• Material: Non-consumable substrates
• Function: Facilitates electron transfer without dissolution
• Key use: Precious metal plating (white gold, etc.)
› Plating Solution
Contains ions of the target metal. Composition and concentration determine coating thickness, adhesion, and appearance.
› Plating Tank
Material Requirements:
• Must handle corrosive environments and thermal cycling
• Typical choices: polypropylene or 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.
Air Cooling:Heat dissipation fan + air duct + comb heat sink
Water Cooling：Built-in water circulation line
