Advanced Built-in Protection Systems
This rectifier integrates a comprehensive suite of safeguards to ensure operational reliability in harsh industrial environments. It includes over-voltage protection (OVP) that triggers within 50 microseconds to prevent damage from voltage spikes, over-current protection (OCP) that limits output to 105% of rated current, and short-circuit protection (SCP) that instantaneously shuts down the output. Additional systems include over-temperature protection (OTP) with automatic fan speed increase and alarm, phase-loss detection for three-phase input, and ground fault monitoring to detect leakage currents in electrolysis tanks. All protection events are logged with timestamps for troubleshooting, and the unit automatically resets after fault clearance to minimize downtime. The microsecond-level response time ensures that even transient faults in nickel lead recovery processes are mitigated without interrupting production.

Target Industrial Applications
This 12V 6000A rectifier is engineered for high-efficiency DC power delivery in electrolysis-based processes, specifically tailored for nickel and lead recovery from industrial wastewater. Primary applications include nickel electrowinning in purification plants where precise current control is critical for metal deposition quality, lead electrowinning for battery recycling operations, and heavy metal removal in wastewater treatment facilities. It also supports copper electrowinning, zinc recovery, and precious metal refining where high current density is required. In hard anodizing and electroplating lines, it provides stable DC output for thick coating applications, and its adjustable voltage range makes it suitable for electroforming and electrocleaning processes in metal finishing shops.

Customization and Tailored Engineering Services
GAOHUI offers full customization of this rectifier to match specific process requirements, with capabilities spanning 1V to 1000V and 1A to 100,000A, all with AC input and DC output only. Custom functional modules include a Digital Process Timer for precise batch control, Multi-Stage Programmable Profile Control for ramping current in steps, Ampere-Minute Integrator for total charge monitoring, Automatic Reverse Polarity for periodic reversal in electroplating, and Soft-Start Ramp-Up to prevent current surges. Control options range from Local/Remote via Push-Button or HMI Touch Screen, with communication interfaces such as RS485 Modbus RTU, Ethernet, and 4-20mA analog output. For pulsed applications, we integrate Pulse Functions with adjustable duty cycle from 1% to 100% and frequency from 1Hz to 3000Hz, enabling advanced waveform shaping for nickel lead recovery. Our engineering team works directly with your facility to design a custom current voltage rectifier that optimizes throughput and energy efficiency.
