GAOHUI 18V 2000A Hard Chrome Rectifier (IGBT Precision Power)

For industrial chrome finishers who demand zero voltage ripple and consistent deposit thickness across complex geometries, the GAOHUI 18V 2000A hard chrome rectifier transforms your plating workflow. Engineered as a high-efficiency IGBT switched-mode power supply, this unit delivers rock-solid 18-volt DC output with continuous current adjustment from zero to 2000 amperes, effectively eliminating the voltage spikes and waveform irregularities that plague traditional silicon-controlled rectifiers. As a trusted industrial high frequency rectifier factory, we design for up to 92% efficiency, reducing your electrical overhead on every run.
PART 1 KEY FEATURES & ENGINEERING HIGHLIGHTS
Advanced IGBT Inverter Topology – Replaces heavy mains-frequency transformers with a compact, air-cooled high-frequency switching stage, providing precise output regulation and improved power factor correction.
True Digital Control – Front-panel digital meters display voltage and current with resolution down to 1 ampere, allowing operators to dial in exact process conditions for decorative chrome to heavy build hard chrome.
Robust Construction – Sealed NEMA-rated enclosure and industrial-grade components ensure sustained operation in harsh acidic plating environments; internal bus bars and oversized heatsinks handle sustained 2000A load without derating.
Full Adjustability – Output voltage continuously variable from 0-18V DC; output current continuously adjustable 0-2000A DC, giving you complete process flexibility regardless of part surface area or bath chemistry.

PART 3 ADVANCED BUILT-IN PROTECTION SYSTEMS
Shield your workpieces and capital equipment with multi-layer safeguards: over-voltage lockout, over-current electronic limiting, short-circuit automatic shutdown, reverse polarity alarm, and thermal over-temperature trip. Each fault condition triggers a visual indicator and a dry-contact output for external alarm integration. The soft-start circuit eliminates inrush current spikes during power-up, protecting both the rectifier and your upstream breaker panel.
PART 4 TARGET INDUSTRIAL APPLICATIONS
Hard Chrome Plating – Ideal for hydraulic rods, piston rings, die components, and aerospace landing gear requiring 50+ Rockwell C hardness layers.
Decorative Chrome Finishing – Offers the smooth voltage curve needed for bright chrome over nickel on automotive trim, bathroom fixtures, and motorcycle parts.
High-Speed Chrome Plating – High current density capability supports rapid deposition rates, reducing cycle times without degrading deposit micro-structure.
General Electroplating – Compatible with nickel, copper, zinc, tin, silver, and gold processes in barrel, rack, or vibratory finishing lines.
PART 5 CUSTOMIZATION AND TAILORED ENGINEERING SERVICES
Your production line is unique, and your rectifier should match it precisely. GAOHUI enables comprehensive customization across the full power spectrum: 1V to 1000V DC output voltage, 1A to 100,000A DC output current, all with 3-phase AC input. Every unit undergoes factory load testing with hard chrome simulation.
Selectable add-on modules include:
Process Timer Integration – Cyclic forward/reverse plating for improved thickness uniformity on complex parts.
Multi-Stage Profile Control – Up to 10-step current/voltage ramping profiles programmable per recipe.
Ampere-Minute Integrator – Coulomb counting for precise thickness control and bath replenishment logging.
Automatic Reverse Polarity – Programmable electro-cleaning cycle without manual cable swapping.
Soft-Start Ramp – Adjustable from 1 to 30 seconds to prevent thermal shock to thin sections.
Communication Interfaces – RS485 Modbus RTU, Ethernet TCP/IP, or analog 4-20mA for PLC/DCS integration.
Pulse Function – Adjustable frequency 1-3000Hz and duty cycle 1-99% for pulse reverse plating where enhanced grain refinement is needed.
