Sodium Hypochlorite Generator – 12V 2000A Electrolysis Rectifier | GAOHUI High-Efficiency DC Power Supply

Engineered for the relentless demands of on-site brine electrolysis, this GAOHUI 12V 2000A DC power supply delivers precise, unidirectional current to drive hypochlorite generation with unwavering stability. As a dedicated electrolysis rectifier, it transforms raw AC input into pure DC output, ensuring optimal salt-to-chlorine conversion rates while minimizing cell voltage fluctuations. Designed for water disinfection applications, this unit replaces dangerous chemical storage with safe, on-demand chlorine production, offering a lower total cost of ownership compared to traditional gas chlorination systems.
PART 1: KEY FEATURES & ENGINEERING HIGHLIGHTS
This unit is manufactured by a trusted industrial high frequency rectifier factory, utilizing IGBT (Insulated Gate Bipolar Transistor) switching technology to achieve efficiency ratings above 92%. Unlike bulky thyristor-based predecessors, the high-frequency design significantly reduces transformer size, providing a compact footprint ideal for skid-mounted electro-chlorination packages, offshore platforms, and municipal water treatment plants.
The 12V 2000A configuration is specifically optimized for sodium hypochlorite cells, maintaining tight voltage regulation to protect electrode coatings. The rectifier delivers exceptionally low ripple, which is critical for preventing cathode passivation and ensuring a consistent chlorine output per ampere-hour. With a digital control system, operators can precisely monitor voltage, current, and total charge passed, enabling accurate dosing for disinfection processes.

PART 3: ADVANCED BUILT-IN PROTECTION SYSTEMS
Operational continuity in water treatment is non-negotiable. This rectifier includes comprehensive fault protection to guard both the power supply and the electrolytic cell. The system features rapid short-circuit cutoff (<1ms), reverse polarity alert, and output overvoltage clamping. Thermal monitoring on both the heat sink and the IGBT modules triggers a controlled shutdown before component stress occurs, while phase-loss detection prevents single-phasing damage.
Additionally, the unit is equipped with a dedicated overcurrent protection curve that matches the electrochemical load profile, preventing nuisance trips while maintaining high current density for efficient chlorine production. The control circuit is electrically isolated, protecting low-voltage logic components from high-voltage transients. This robust protection architecture ensures that our heavy-duty DC power supply price reflects long-term reliability, reducing unscheduled downtime.
PART 4: TARGET INDUSTRIAL APPLICATIONS
This power supply excels in decentralized water disinfection scenarios. It is the core component for generating sodium hypochlorite through the electrolysis of a weak brine solution for municipal drinking water chlorination, wastewater treatment, and cooling water bio-fouling control. It also serves aquaculture facilities, swimming pool systems, and industrial effluent treatment requiring residual chlorine.
In cruise ships and offshore oil rigs, the compact footprint and high corrosion resistance of the enclosure ensure reliable operation in saline atmospheres. The rectifier supports both continuous and batch electrolysis modes, adapting to variable flow-rate disinfection demands. It allows for the safe production of up to 5 lbs/day of equivalent chlorine, eliminating the logistics and safety risks associated with transporting hazardous chemicals.
PART 5: CUSTOMIZATION AND TAILORED ENGINEERING SERVICES
As a specialized IGBT rectifier manufacturer, we do not believe in a one-size-fits-all approach. While this standard 12V 2000A unit covers most standard cells, the GAOHUI engineering team offers full factory customization across a spectrum of 1V-1000V and 1A-100,000A. We tailor the operational profile to your exact electrode surface area and desired chlorine output.
Optional advanced modules are available to optimize the electrolysis process. A Process Timer allows fully automated batch cycling, while Multi-Stage Profile Control enables you to sequence current ramps to protect delicate catalytic coatings. An Ampere-Minute Integrator precisely tracks accumulated charge, prompting automatic electrode cleaning cycles. For system redundancy, we offer Automatic Reverse Polarity pulse functions (1-3000Hz adjustable) to decalcify electrodes in situ. All units can be equipped with industrial interfaces including RS485 Modbus RTU, Ethernet TCP/IP, and 4-20mA analog controls, facilitating seamless integration into your SCADA or PLC system. We provide a custom current voltage rectifier solution that meets your unique specifications.
