Sodium Hypochlorite Generator – 12V 2000A Electrolysis Rectifier by GAOHUI

Engineered exclusively for on-site brine electrolysis, the GAOHUI 12V 2000A rectifier is a heavy-duty DC power supply designed to maximize chlorine output in electro-chlorination systems. This unit converts 3-phase AC mains into pure, stable low-voltage high-current DC, fueling the electrochemical reaction that produces sodium hypochlorite for water disinfection. Built to outlast standard water treatment power supplies, it eliminates voltage drift and ripple that degrade cell efficiency.
Part 1 Key Features & Engineering Highlights
PURE DC OUTPUT FOR HIGH YIELD
Delivers 2000A of filtered DC power, reducing ripple to under 3%. This prevents electrode passivation and ensures consistent sodium hypochlorite production for industrial water disinfection. The power module is engineered for 24/7 batch processing.
HIGH-EFFICIENCY IGBT TECHNOLOGY
This unit utilizes advanced IGBT switching at ultrasonic frequencies, achieving a conversion efficiency above 92%. It minimizes heat loss within the electrolyzer, directly lowering the heavy-duty DC power supply price per liter of chlorine generated.
ROBUST 3-PHASE INPUT HANDLING
Specifically designed to handle unstable industrial grid voltages (340V-480V AC). The internal decoupling capacitors smooth out surges, protecting the downstream electrolytic cell from sudden power spikes common in chemical plants.
CORROSION-RESISTANT ENCLOSURE
Housed in a powder-coated steel cabinet with conformal coated PCBs. The intake air filter reduces salt mist ingress, extending the service life of the industrial high frequency rectifier factory system in humid, saline environments.

Part 3 Advanced Built-in Protection Systems
Temperature Cut-off: An NTC sensor on the IGBT heatsink triggers thermal shutdown at 85°C, preventing catastrophic failure. Auto-restart occurs once cooled.
Short Circuit & Overload: Instantaneous current limiting with 1 microsecond response time. The unit automatically locks out and displays an alarm code if a short occurs in the electrolytic cell.
Over/Under Voltage: Detects phase loss or brownout conditions. The IGBT rectifier manufacturer configurable undervoltage threshold prevents the drive from attempting startup on low supply.
Reverse Polarity Protection: Built-in Schottky diode network prevents damage if the DC output leads are connected backwards to the titanium electrodes.
Part 4 Target Industrial Applications
On-Site Brine Electrolysis: Perfect for municipal and industrial electro-chlorination systems requiring continuous sodium hypochlorite generation for water disinfection.
Cooling Water Treatment: Suitable for power plants and petrochemical facilities that need to prevent biofouling in seawater cooling loops.
Ballast Water Treatment: Complies with IMO D-2 discharge standards by powering electrolytic cells that produce active substances.
Wastewater Disinfection: Used in municipal WWTPs to provide a safe, non-transportable chlorine source for effluent disinfection.
Part 5 Customization and Tailored Engineering Services
As a dedicated custom current voltage rectifier provider, GAOHUI offers full tailorability. Any standard unit can be modified to your specific line. Our factory custom capability ranges from 1V to 1000V and 1A to 100,000A (Input: AC / Output: DC only).
We integrate these advanced modules into your Sodium Hypochlorite Generator power supply:
Process Timer & Profile Control: Set specific amperage ramps and dwell times to match the salinity of your brine. Prevents over-chlorination and salt waste.
Ampere-Minute Integrator: Integrates current over time to precisely dose chlorine without expensive ORP probes. Ideal for batch disinfection.
Automatic Reverse Polarity: Engineered to reverse the DC flow polarity on a user-defined schedule (e.g., every 10 minutes) to automatically de-scale the titanium electrodes, extending cell life by 300%.
Soft-Start & Slew Rate Limiting: Prevents hydraulic shock in the piping system. Current ramps up over 10 seconds.
Advanced Interface Control: Includes RS485 Modbus RTU, Ethernet (TCP/IP), and 4-20mA analog outputs for full SCADA integration. Custom Pulse Function available (1-3000Hz adjustable) to enhance molecular disassociation efficiency.
