GAOHUI 18V 3000A High-Efficiency IGBT Hard Chrome Plating Rectifier with Microsecond Fault Response

Key Features
– Microsecond-Level Fault Response: Advanced IGBT switching technology detects and isolates arc faults, short circuits, and overcurrent conditions in under 2 microseconds, protecting both the rectifier and sensitive plating baths.
– Precision Voltage & Current Control: Integrated remote controller box allows for real-time, remote adjustment of output from 0-18V and 0-3000A, ensuring repeatable, high-quality hard chrome deposits.
– High Efficiency & Low Ripple: Converts three-phase 400V/480V AC input to pure DC with >92% efficiency and less than 3% ripple, eliminating voltage spikes that compromise chrome adhesion.
– Robust Industrial Build: Designed for continuous heavy-duty operation in harsh environments, with forced air cooling, corrosion-resistant cabinets, and a 2-year warranty.

Technical Specifications

Built-in Protection Systems
– Overvoltage Protection: Automatic shutdown if output exceeds 19.5V.
– Overcurrent Protection: Instantaneous trip at 3200A.
– Short Circuit Protection: Microsecond IGBT gate blocking prevents damage.
– Overheating Protection: Thermal sensors trigger fan speed increase and shutdown at 65°C.
– Phase Loss Protection: Monitors all three input phases; rectifier will not start if one phase is missing.

Main Applications
– Hard Chrome Plating: Delivers stable, ripple-free DC for uniform chrome deposition on large parts like hydraulic rods, rolls, and molds.
– Electroplating of Heavy Machinery: Suitable for high-current nickel, copper, and zinc plating processes.
– Anodizing & Electroforming: Provides precise voltage control for hard anodizing and electroforming of complex geometries.
– Industrial Electrolysis: Powers large-scale electrolytic cells for metal recovery and water treatment.
