GAOHUI introduces the HF60K series industrial high frequency rectifier factory, a 12V 6000A heavy-duty DC power supply price solution specifically engineered for the rigorous demands of nickel lead recovery electrowinning and metal electrolysis. This unit delivers precise 6000 amperes of constant or pulsed DC current at 12 volts nominal, operating at >90% efficiency in a compact forced-air cooled chassis designed for 24/7 continuous use. Unlike traditional SCR-based units, this IGBT rectifier manufacturer provides ripple below 5% and instant dynamic response, essential for maximizing current density and recovery yield in nickel and lead winning cells. The built-in process timer and multi-stage profile control allow you to program ramping and hold sequences, significantly improving deposit quality while reducing energy per ton. Every system is backed by GAOHUI’s engineering support for integrating with existing tankhouse automation via RS485 or Ethernet.

Part 1 Key Features & Engineering Highlights
High-Frequency IGBT Topology – Switches at 20-50 kHz for a compact footprint, low audible noise, and elimination of heavy line-frequency magnetics. Reduces floor space requirements in crowded electro-winning facilities.
12V 6000A Constant Current Regulation – Maintains set output within ±0.5% even with fluctuating AC line or changing bath resistance. Critical for consistent lead stripping and nickel plate uniformity.
Air-Forced Cooling with Redundant Fans – Designed for ambient temperatures up to 45°C without derating. Built-in thermal management enables sustained full-load output during summer peak production.
Digital Control with HMI Touch Interface – Local 5.7-inch touchscreen provides real-time V, A, kWh, and accumulated Ampere-Minutes. Users can store ten independent recipes for different product grades.
Pulse Function 1-3000Hz – Enable pulse/pulse reverse current for improved throwing power and deposit morphology adjustments. Synchronizes with process timers for complex plating cycles.

Part 3 Advanced Built-in Protection Systems
This heavy-duty DC power supply price model is safeguarded against real-world industrial fault conditions that can damage equipment or halt production. The control logic continuously monitors multiple parameters and triggers immediate discharge of output capacitors upon shutdown. Critical protection layers include:
| Over-Voltage Protection (OVP) | Adjustable trip point, latches output to zero in under 2 milliseconds |
| Over-Current Protection (OCP) | Fold-back current limiting prevents sustained short-circuit damage |
| Over-Temperature Protection (OTP) | Triggers at 85°C heatsink temperature, auto-resets after cool-down |
| Phase Loss & Imbalance Protection | Detects open phase or low voltage on input line; inhibits operation |
| Soft-Start Circuitry | Gradual voltage ramp prevents bus capacitor inrush and mechanical relay chattering |
Part 4 Target Industrial Applications
Nickel Recovery Electro-winning
Precise CC control at 12V for optimal nickel deposit from sulfate/chloride solutions. Pulsing reduces pitting and stress in high-purity nickel cathode production.
Lead Electrowinning
Delivers the high current density (300-500 A/m²) required for efficient lead recovery from waste battery paste or ores. Low ripple reduces sludge formation and energy consumption.
Heavy Metal Wastewater Recycling
Used in specialized electrochemical cells to recover copper, zinc, nickel, and lead from industrial rinse waters. Custom current voltage rectifier profile adjusts per metal ion concentration.
Electro-dialysis & Water Treatment
Provides stable DC to electrodialysis stacks for desalination or chemical recovery. The 4-20mA interface can be slaved to flow meters for proportional control.
Metal Finishing & Plating
Pulse reverse function (1-3000Hz) enables gold, silver, and nickel plating with improved leveling and micro-throwing power in automated barrel or rack lines.
Part 5 Customization and Tailored Engineering Services
