Built-in Protection Systems
The GAOHUI 18V 3000A rectifier includes overcurrent protection, overvoltage protection, overtemperature shutdown, short circuit protection with automatic recovery, phase loss detection, and soft-start ramp-up to prevent bath disturbance. Microsecond-level fault response instantly cuts output during any abnormal condition, safeguarding your valuable chrome plating solution and workpieces.
Main Applications
This industrial rectifier is specifically designed for hard chrome plating, decorative chrome plating, and anodizing processes. It is ideal for plating large metal parts, hydraulic cylinders, mold surfaces, and automotive components requiring precise 18V DC power at high current. Also suitable for PCB electroplating, copper/nickel/zinc plating, and other surface finishing operations requiring low ripple DC.
Customization and Tailored Engineering Services
GAOHUI factory offers complete customization for your specific process requirements across 1V-1000V and 1A-100,000A output ranges, AC-DC only. Available custom functions include Digital Process Timer for precise plating cycles, Multi-Stage Programmable Profile Control for complex ramp and hold sequences, Ampere-Minute Integrator for thickness monitoring, Automatic Reverse Polarity for pulse plating, and Soft-Start Ramp-Up to prevent current shock. Choose Local/Remote Control via push-button panel or HMI Touch Screen. Communication interfaces include RS485 Modbus RTU, Ethernet, and 4-20mA analog control. Pulse Functions are adjustable with 1-100% duty cycle and 1-3000Hz frequency for specialized chrome plating applications.
