Chrome Plating – 18V 2000A Custom Current Voltage IGBT Rectifier by GAOHUI

Executive Summary
This GAOHUI 18V 2000A power supply is engineered specifically for demanding chrome plating applications where waveform purity and current stability are non-negotiable. As a trusted industrial high frequency rectifier factory, we deliver a three-phase waveform free of destructive voltage spikes, ensuring optimal deposit adhesion for hard chrome, decorative chrome, and high-speed chrome plating on automotive parts finishing lines. Unlike bulky, inefficient silicon-controlled rectifiers, this high-frequency IGBT design cuts energy waste, reduces floor space, and provides ±0.5% steady-state regulation for repeatable, dense chrome deposits.
Part 1 Key Features & Engineering Highlights
Power Factor Excellence – Built-in automatic power factor correction achieves ≥0.95 PF, slashing reactive power penalties and improving facility electrical efficiency.
Precision Deposit Control – High-frequency switching delivers a smooth DC output with less than 1% ripple at rated load, eliminating the anode burning and rough edge issues common with less refined rectifiers.
Space and Weight Reduction – Compact chassis occupies 60% less floor space than traditional 2000 amps three phase rectifier designs, making it ideal for production lines with cramped tank layouts.
Integrated Digital Intelligence – Standard communication interface supports real-time monitoring and data logging through RS485 Modbus RTU or Ethernet, enabling seamless integration with plant automation.

Part 3 Advanced Built-in Protection Systems
Overcurrent and Short-Circuit Protection – Instantaneous shutdown when current exceeds 110% of set value, preventing anode damage and bus bar overheating.
Overvoltage Surge Suppression – Internal varistor network clamps voltage transients, safeguarding downstream workpieces and chemicals from destructive spikes.
Thermal Overload with Auto-Recovery – Three independent temperature sensors monitoring IGBT junction and transformer core; fan speed automatically ramps under sustained load.
Soft-Start Circuitry – Gradual voltage ramp-up over 1-5 seconds prevents sudden current draw on the three-phase mains, protecting site breakers and contactors.
Part 4 Target Industrial Applications
Hard Chrome Plating – Required for hydraulic rod restoration and die repair; the stable 18V output ensures micro-crack free deposits at high current densities.
Decorative Chrome Finishing – For automotive parts finishing, bumpers, and bright trim, the low-ripple DC produces mirror-like surfaces without burnt corners.
High-Speed Chrome Plating – When production throughput is critical, this rectifier maintains constant current across a full tank of rotating parts, even during part loading cycles.
Multi-Metal Sequencing – Can be used for copper strike, nickel underlayer, and chrome top coating in a single power supply by using the pulse function (1–3000Hz adjustable).
Part 5 Customization and Tailored Engineering Services
As a specialized IGBT rectifier manufacturer with over 2000 units annual capacity, GAOHUI offers extensive configuration options. You specify the parameter envelope – 1V-1000V, 1A-100,000A, AC input – and we engineer a DC-only output solution with your chosen interface modules.
Process Timer – Multi-step timing allows automated plating cycles: pre-dip, ramp-up, plating, ramp-down, and post-dip, with adjustable durations per step.
Multi-Stage Profile Control – Store up to 50 recipes with programmable current/voltage stages, suitable for barrel plating sequences where load changes between cycles.
Ampere-Minute Integrator – Precisely measures total amp-hours delivered; trigger a control output at a preset value for automatic bath addition or part ejection.
Automatic Reverse Polarity – Switchable for periodic reverse plating (PR cycles) where anodic pulse strips nodes and improves throwing power.
Soft-Start and Interface Communication – All units come with RS485 Modbus RTU as standard; Ethernet, 4-20mA analog outputs, or a full PLC interface are drop-in options.
Pulse Functions – Choose from 1Hz to 3000Hz pulse frequency with adjustable duty cycle (0%–100%) for high-speed plating processes requiring micro-pulse reversals.
