GAOHUI 30V 2000A Electrocoagulation Rectifier – Industrial High Frequency DC Power Supply for Wastewater Flocculation and Heavy Metal Precipitation

Part 1: Key Features & Engineering Highlights
– Heavy-duty DC power supply price optimized for high-volume electrocoagulation systems: This 30V 2000A unit delivers 60kW of stable, ripple-free DC output, engineered for continuous 24/7 operation in demanding industrial wastewater treatment plants. As a leading IGBT rectifier manufacturer, GAOHUI integrates advanced Germany technology cooling system with oversized aluminum heat sinks and dual-speed fans, ensuring thermal stability even at full rated load.
– Custom current voltage rectifier with precision control: The unit features a 0-30V and 0-2000A fully adjustable range, with 0.1% voltage and current regulation. The industrial high frequency rectifier factory design uses IGBT switching at 20kHz, reducing transformer size and improving efficiency above 92%, directly lowering your operational cost per cubic meter of treated water.
– Electrocoagulation EC water treatment optimized output: Built-in automatic reverse polarity function with adjustable duty cycle (1-100%) and frequency (1-3000Hz) prevents electrode passivation and scaling, critical for maintaining flocculation efficiency in heavy metal precipitation applications. The pulse function allows fine-tuning of current waveforms for specific contaminant removal.
– Integrated digital process timer and multi-stage programmable profile control: Operators can store up to 10 distinct treatment profiles, each with independent voltage, current, ramp time, and polarity reversal sequences. This enables automated batch processing for variable influent loads without manual intervention.
– Ampere-minute integrator with totalizer: An embedded digital counter tracks cumulative charge delivered, essential for precise dosing of coagulant current in wastewater flocculation. The data can be logged via RS485 Modbus RTU or Ethernet for integration with SCADA systems.

Part 3: Advanced Built-in Protection Systems
The GAOHUI 30V 2000A electrocoagulation rectifier is equipped with a comprehensive suite of protective features to safeguard both the power supply and the treatment process. These include overvoltage protection (OVP) with adjustable threshold, overcurrent protection (OCP) with fast-acting electronic trip, overtemperature protection (OTP) with automatic fan speed control and shutdown if critical limits are exceeded, short-circuit protection with automatic recovery, and phase loss protection to prevent damage from unbalanced three-phase input. Additionally, a soft-start ramp-up function prevents current inrush during initial power-on, extending the life of downstream electrolytic cells. All protection events are logged with time stamps for troubleshooting and compliance reporting.

Part 4: Target Industrial Applications
– Electrocoagulation (EC) for wastewater flocculation and heavy metal precipitation in electroplating, mining, and chemical industries.
– Electrolytic descaling and ballast water treatment systems for marine and desalination plants.
– Electrowinning of metals from industrial effluents and process solutions.
– Hard anodizing and precious metal plating where precise current control is critical for coating uniformity.
– Seawater electrolysis for chlorine generation in water disinfection and biofouling control.

Part 5: Customization and Tailored Engineering Services
As a dedicated industrial high frequency rectifier factory, GAOHUI offers full customization from 1V to 1000V and 1A to 100,000A, AC-DC only. For the 30V 2000A platform, we can integrate custom functional modules to match your specific process requirements: Digital Process Timer for automated batch cycles, Multi-Stage Programmable Profile Control with up to 100 step sequences, Ampere-Minute Integrator for precise charge dosing, Automatic Reverse Polarity with user-defined waveform patterns, and Soft-Start Ramp-Up to protect electrodes and reduce mechanical stress. Local and remote control options are available via push-button panel or 7-inch HMI Touch Screen with intuitive menu navigation. For system integration, we support RS485 Modbus RTU, Ethernet TCP/IP, and 4-20mA analog interfaces. The pulse function allows independent adjustment of duty cycle from 1% to 100% and frequency from 1Hz to 3000Hz, enabling fine-tuned electrochemical reactions for specialized wastewater flocculation and heavy metal precipitation processes.
