Part 1 Key Features & Engineering Highlights
This unit is not a power supply; it is a process orchestration engine. It is built around a heavy-duty IGBT topology designed to survive years of non-stop duty cycles.
Direct Polarity Reversal for EC: Integrated automatic reverse polarity (ARP) cycles prevent passivation of sacrificial electrodes. The timing is fully programmable to optimize iron or aluminum dosage rates per your specific wastewater chemistry.
High-Frequency Efficiency: Operating at >20kHz switching frequency, this rectifier delivers true linear DC output with ripple under 1%. This is critical for preventing re-agglomeration of flocs in electrocoagulation chambers.
Closed-Loop Control: Switch seamlessly between Constant Voltage (CV) and Constant Current (CC) modes. For EC, CC mode is typically preferred to maintain consistent current density as electrode gaps change due to consumption.
Global Input Compatibility: Accepts 380V, 480V, or 600V 3-phase AC input with automatic phase correction. PFC technology ensures you are not paying the utility for wasted reactive power.
Compact, Clean Design: Air-cooled dual-fan system with corrosion-resistant coating on all PCBs. No water-to-water heat exchangers required, reducing maintenance costs versus older thyristor systems.

Part 3 Advanced Built-in Protection Systems
Your capital investment is fully shielded. Beyond basic overcurrent and overvoltage, this unit features a multi-stage safety architecture designed for the harsh conditions of a treatment plant floor. This includes:
Primary Protection Suite: Short circuit, overload, phase loss, and overheating on heat sink.
Secondary Process Protection: Automatic shutdown if the inter-electrode gap senses a low-impedance short (e.g., from loose scrap metal entering the tank).
Dry Run Protection: The power supply can be configured to only enable when the external coolant or submersed electrode sensor is primed. This prevents catastrophic melting of the bus bars.
IoT-Ready Communication Interface: Standard IGBT rectifier manufacturer platform integrates Modbus RTU over RS485, Ethernet TCP/IP, and isolated 4-20mA analog control. This enables full synchronization with SCADA systems for remote monitoring and data logging of kWh, Ah, and total run time.
Part 4 Target Industrial Applications
This specific heavy-duty DC power supply price model is optimized for industrial-scale electrocoagulation (EC). It excels in processes requiring high amperage at low voltage. Typical use cases include:
Oil & Gas produced water treatment for contaminant removal.
Textile dye wastewater decolorization and TSS reduction.
Metal finishing rinse water: Facilitates heavy metal precipitation like Chromium, Nickel, and Copper.
Landfill leachate treatment: Reduces COD/BOD and colloidal turbidity.
Mining runoff remediation: Handles sulfide and arsenic flocculation at high throughput.
Part 5 Customization and Tailored Engineering Services
This 30V 2000A configuration is a standard building block. As a custom current voltage rectifier partner, we can engineer any variation between 1V-1000V and 1A-100,000A. All units feature AC input to DC output isolation.
We specialize in adding Process Control Modules tailored for electrochemistry:
Multi-Stage Profile Control (MSPC): Pre-set a “recipe” of current ramps and holds for batch processing.
Ampere-Minute Integrator (AHM): Precisely dose the coulombs of charge delivered to the water, ensuring repeatable chemical dosage without monitoring pH constantly.
Automatic Reverse Polarity (ARP) with Soft Start: Ramp up current after each polarity swap to avoid shock to the electrode structure.
Pulse Functions: Adjustable square wave pulse between 1-3000Hz for enhanced micro-floc formation in high TSS streams.
Interfaces: Standard RS485 Modbus RTU, Ethernet IP, 4-20mA analog. We can also integrate PLC relays for external alarms or chemical dosing pumps.
