Industrial DC Plating Supply 12V 1000A for Hard Chrome Surface Finishing

This unit delivers a pure, ripple-free DC output from a 380V three-phase input, ensuring the dense, crack-free deposits essential for industrial hard chromium. Engineered for continuous heavy-duty operation, this air-cooled system eliminates voltage spikes that typically cause pitting in thick chrome builds. As a leading industrial high frequency rectifier factory, we suppress harmonic distortion to protect upstream equipment while delivering the consistent current density your process demands. If you are evaluating a heavy-duty DC power supply price, consider that this model achieves over 92% efficiency, directly cutting kWh costs per plated part compared to traditional SCR units.
Part 1 Key Features & Engineering Highlights
HEXAVALENT CHROME OPTIMIZED WAVEFORM: Proprietary IGBT switching at 25kHz produces a phase-controlled output free of the harmonic noise that ruins hard chrome adhesion. This ensures uniform current distribution across complex geometries.
AIR COOLED DURABILITY: Zero liquid cooling risks. Heavy-duty aluminum heat sinks and variable-speed fans manage thermal loads in dusty plating environments. Designed for 100% full-load continuous duty at 45C ambient.

Part 3 Advanced Built-in Protection Systems
FLAT-OUT SAFETY NETWORK: Automatic shutdown on over-current, over-voltage, over-temperature, short-circuit, and phase loss. The system self-recovers once fault conditions clear, preventing scrapped loads during overnight runs.
AMBIENT FAULT LOGIC: Embedded controller monitors internal temperatures and input voltage sag. If line power dips below -15%, the unit throttles output gradually rather than hard tripping, keeping production lines moving.
Part 4 Target Industrial Applications
HARD CHROME BARREL PLATING: Delivers the steady current required for building thick, wear-resistant layers on hydraulic rods and mold tools.
HEXAVALENT CHROME LINE RETROFITS: Direct replacement for aging thyristor rectifiers in facilities switching to IGBT efficiency. Reduces cooling load on chrome bath refrigeration systems.
HEAVY-DUTY PLATING BARREL: Powers nickel, copper, and zinc barrels requiring 800-1000A surges without voltage drop. Ideal for high-throughput job shops running 24/7 schedules.
