Electrocatalytic Oxidation – 48V 1000A Industrial High Frequency Rectifier Factory Direct DC Power Supply by GAOHUI

This 48V 1000A direct-current power source is precision engineered for demanding advanced oxidation processes (AOPs) used in industrial effluent treatment, specifically targeting electro-Fenton advanced oxidation and COD removal applications. Manufactured at our industrial high frequency rectifier factory, this unit delivers stable, ripple-free DC output to drive aggressive electro-oxidation reactions, ensuring maximum degradation of organic pollutants. The power supply operates in either voltage-regulated current-limited mode or current-regulated voltage-limited mode, with seamless switching between the two, providing precise electrochemical control for variable load conditions. For buyers evaluating a heavy-duty DC power supply price, this unit offers high-efficiency IGBT switching topology that reduces energy waste while delivering consistent 1000A current for continuous industrial operations. As a trusted IGBT rectifier manufacturer, GAOHUI ensures this model meets rigorous lifecycle testing for harsh chemical environments found in effluent treatment plants.
PART 1 KEY FEATURES & ENGINEERING HIGHLIGHTS
High Frequency IGBT Switching Topology: Utilizes advanced insulated-gate bipolar transistor technology for efficiency above 92%, minimizing thermal generation and operational costs.
Dual-Mode Regulation: Seamless voltage-regulated current-limited and current-regulated voltage-limited modes with automatic crossover, critical for electro-Fenton advanced oxidation stability.
Ultra-Low Ripple Output: Filtered DC output with less than 1% ripple, protecting sensitive electrolytic cell membranes and ensuring consistent COD removal rates.
Rugged Industrial Construction: Corrosion-resistant coating and IP54-rated enclosure designed for high-humidity, chemically aggressive effluent treatment environments.
High Power Density: Compact rack-mount design delivering 48kW output (48V x 1000A) in a standard 19-inch 6U chassis, saving valuable floor space.
Thermal Management: Intelligent forced-air cooling with redundant fans and over-temperature protection ensures continuous duty cycles even at full rated load.

PART 3 ADVANCED BUILT-IN PROTECTION SYSTEMS
The 48V 1000A rectifier integrates a multi-layered safety architecture: Input over/under-voltage lockout, output over-voltage crowbar protection, instantaneous over-current cutoff, short-circuit current limiting, thermal shutdown with auto-restart hysteresis, and reverse polarity protection on DC bus. These safeguards prevent catastrophic failure during industrial effluent treatment where electrode scaling or gas bubble formation may cause sudden impedance changes. A redundant watchdog timer monitors internal logic, automatically rebooting the control system if a fault condition is not cleared within 90 seconds.
PART 4 TARGET INDUSTRIAL APPLICATIONS
This power supply is purpose-built for electro-Fenton advanced oxidation in industrial effluent treatment, delivering high-density electron flow to generate Fenton’s reagents in situ for COD removal. Additional applications include electrocoagulation systems for heavy metal precipitation, electroflotation for oil-water separation, batch electrolysis reactors for organic destruction, and DC bus architectures for pilot-scale AOP demonstrations. Suitable for textile dyeing effluent, pharmaceutical wastewater, petrochemical refinery streams, and landfill leachate treatment.
