Sodium Hypochlorite Generator – 12V 2000A Industrial-Grade High Frequency Electrolysis Rectifier

EXECUTIVE SUMMARY
This 12V 2000A rectifier is a dedicated power conversion system engineered specifically for on-site brine electrolysis and electro-chlorination systems used in water disinfection chlorine generation. By converting 3-phase AC mains into pure, ultra-stable low-voltage high-current DC, this unit delivers the precise energy profile required to efficiently crack sodium chloride brine into sodium hypochlorite. As a leading IGBT rectifier manufacturer, we designed this unit to maximize current density across electrolytic cell stacks while minimizing ripple and energy waste, delivering a reliable, continuous duty power source for 24/7 municipal and industrial hypochlorite production. Compare this heavy-duty DC power supply price against inferior SCR (thyristor) units—our high-frequency IGBT topology yields over 92% efficiency, reduced heat dissipation, and a significantly smaller footprint.
PART 1: KEY FEATURES & ENGINEERING HIGHLIGHTS
Full-Range Adjustable Output – Voltage is smoothly adjustable from 0 to 12V DC, current from 0 to 2000A, enabling precise tuning for varying brine temperatures, salinities, and flow rates.
High-Frequency IGBT Architecture – Uses advanced Insulated Gate Bipolar Transistors (IGBT) switching at 18-25 kHz. This eliminates heavy line-frequency transformers, dramatically reducing weight and size while delivering a pure DC waveform with less than 3% ripple—critical for electrode longevity.
Soft-Start & Ramp Control – Integrated soft-start prevents massive inrush current during start-up, protecting both the rectifier and expensive electrolyzer cell stacks. A programmable soft-ramp profile can be set for gradual current application over 1-60 seconds.
Over 92% Energy Efficiency – Directly lowers operating costs per kilogram of chlorine generated. At 2000A and full 12V output, the unit consumes under 26 kW from the AC line.
Compact Modular Design – Occupies roughly 60% less floor space than a comparable SCR unit, easing installation inside existing water treatment rooms or skid-mounted setups.

PART 3: ADVANCED BUILT-IN PROTECTION SYSTEMS
Over-Voltage Protection (OVP) and Under-Voltage Protection (UVP) guard against unstable mains and electrolyzer back-EMF spikes.
Over-Current Protection (OCP) combined with Electronic Short Circuit Protection ensures immediate shutdown if an electrode short or cell leak occurs.
Phase Loss Protection automatically halts output if any AC input phase drops, preventing single-phasing damage to the IGBT modules.
Over-Temperature Protection (OTP) with thermal sensor on both IGBT heatsinks and output bus bars. If internal air temperature exceeds 85°C, the unit reduces output current linearly before performing a controlled shutdown.
Ground Fault Detection – Monitors DC leakage current to ground. Adjustable threshold alarms and optionally triggers a trip if unusually high ground current is detected near the wet electrolyzer environment.
PART 4: TARGET INDUSTRIAL APPLICATIONS
This 12V 2000A sodium hypochlorite generator rectifier is built for continuous, heavy duty service in:
Municipal Drinking Water Disinfection – On-site chlorine generation replacing bulk hypochlorite or chlorine gas transport.
Wastewater Treatment – Produces sodium hypochlorite for oxidation of ammonia, iron, manganese, and for disinfection of effluent.
Cooling Tower Biofouling Control – Injects a constant low dose of electro-chlorine to suppress algae and Legionella growth.
Brine Disinfection Systems Onboard Ships – Ballast water treatment and sanitary effluent treatment where saltwater is readily available.
Swimming Pool & Leisure Facilities – Large-scale onsite sodium hypochlorite production, eliminating the need to store hazardous liquid bleach.
PART 5: CUSTOMIZATION AND TAILORED ENGINEERING SERVICES
As a top custom current voltage rectifier specialist, our factory supports full OEM engineering for application-specific integration. Whatever your DC power needs, we can build it.
Voltage & Current Range – We routinely produce DC output from 1V to 1000V, and from 1A to 100,000A. Input is always AC (single or three-phase). Output is 100% DC.
Process Modules to Add:
Process Timer – Program on/off cycles for automated batch electrolysis.
Multi-Stage Profile Control – Set up to 20 current steps with independent dwell times and ramps for complex cell conditioning.
Ampere-Minute Integrator – Totalizes the exact charge (Ampere-Minutes or Ampere-Hours) delivered, triggering a relay when a dose setpoint is reached.
Automatic Reverse Polarity – Automatic polarity inversion at defined intervals dramatically reduces calcium and magnesium scaling on titanium electrodes.
Soft-Start – Already standard, but can be extended to a slower, multi-day ramp for initial electrode passivation.
Control Interfaces:
RS485 Modbus RTU / TCP – Full remote monitoring and control via SCADA or PLC. Read real-time voltage, current, accumulated Ah, and fault logs.
Ethernet/IP or Profinet – Available on request for integration with modern DCS systems.
4-20mA Analog Control – Allows proportional current control from an external flow meter or Chlorine Residual Analyzer.
Pulse Functions 1-3000Hz Adjustable – For specialized electrochemical reactions and electrocoagulation processes requiring pulsed DC rather than smooth DC.
