GAOHUI Heavy Duty Copper Electrolysis Power Supply (12V 5000A) for High Current SX-EW

Executive Summary
GAOHUI presents a heavy-duty 12V 5000A DC power supply engineered specifically for the rigorous demands of copper electrolysis and solvent extraction electrowinning (SX-EW) processes. This industrial high frequency rectifier factory solution replaces traditional thyristor-based units, delivering up to 87% efficiency while maintaining ripple-free DC output essential for high-grade cathode quality. Built to survive 24/7 operations in copper scrap recycling and primary EW facilities, this unit offers a verifiable industrial high frequency rectifier factory calibrated lifecycle of over 15 years.
Part 1 Key Features & Engineering Highlights
The core advantage of this GAOHUI model lies in its fully digital IGBT inverter topology, providing superior current stability compared to analog SCR designs. The active power factor correction (PFC) circuitry eliminates harmonic distortion to ensure compliance with IEEE 519 standards. With a forced-air cooling system that performs at ambient temperatures up to 55°C, the unit maintains precision regulation within 0.5% for both voltage and current modes.
Key engineered advantages include:
– Dual-loop digital PID controller for instantaneous load response.
– Sealed transformer and busbar assembly preventing copper sulfide corrosion.
– Low-ripple filter bank ensuring peak cathode purity for EW applications.
– Direct drive capability for series tank configurations in copper electrolysis.

Part 3 Advanced Built-in Protection Systems
Overcurrent (OCP) and short-circuit protection respond within 2 microseconds, safeguarding the copper electrolysis tank circuit from catastrophic faults. The embedded input phase-loss and over/under-voltage monitoring prevent uncontrolled rectifier shutdown during grid disturbances. For high-current applications involving copper scrap recycling, the dedicated hardware also includes dry-contact alarms for heat sink overtemperature and cabinet door intrusion. The independent overvoltage crowbar circuit provides redundant defense for the heavy-duty DC power supply price integrity.
Part 4 Target Industrial Applications
Primary application: Copper electrowinning in SX-EW plants, where the 12V DC potential drives pure copper deposition from sulfuric acid electrolytes. This GAOHUI unit also excels in copper scrap electrolytic refining, maintaining homogeneous current density across hundreds of cathode sheets. Auxiliary uses include precious metal recovery from electronic waste and forced electro-winning in solvent extraction circuits for nickel or zinc. The unit is fully compatible with automated crane systems found in large-scale copper electrolysis tankhouses.
Part 5 Customization and Tailored Engineering Services
GAOHUI offers full building-block customization for your process line. The standard unit is modularly scalable within a 1V-1000V (DC) and 1A-100,000A (DC) range, with input voltages configurable from 208V to 690V AC. The IGBT rectifier manufacturer capability includes embedded modules for Process Timer, Multi-Stage Profile Control (up to 8 segment ramp-up/soak/ramp-down cycles), Ampere-Minute Integrator for accurate coulomb counting, and Automatic Reverse Polarity for periodic periodic reverse (PR) plating cycles.
Every unit ships with standard interfaces: RS485 Modbus RTU, Ethernet (TCP/IP), and 4-20mA analog for SCADA integration. Enhanced options include Pulse Functions adjustable from 1 to 3000 Hz with variable duty cycle. The digital Soft-Start feature eliminates electrode thermal shock at power-up. For direct custom current voltage rectifier inquiries, provide your electrolyte chemistry, tank geometry, and desired cathode quality target. GAOHUI engineering will deliver a pre-configured solution matched to your exact copper electrolysis parameters, including a detailed thermal loss report and enclosure layout drawing.
