Heavy Duty Wastewater Rectifier (30V 2000A) for Electrocoagulation EC

Executive Summary
Engineered specifically for demanding electrocoagulation and electrolysis wastewater treatment processes, this 30V 2000A DC power source delivers the precise, controlled energy required for effective heavy metal precipitation and organic flocculation. Unlike standard laboratory supplies, this is a hardened industrial unit designed for continuous 24/7 operation in corrosive environments. It functions as a true electrolysis rectifier, converting high-power AC input into a stabilized, ripple-free DC output to maximize treatment efficiency and electrode lifespan.
Part 1 Key Features & Engineering Highlights
High-Frequency IGBT Topology: Utilizes advanced IGBT switching technology at high frequency for superior energy efficiency (typically 90%+), reducing operational heat and electrical costs compared to traditional SCR thyristor type units.
Precision Current Voltage Regulation: Operates in either constant current (CC) or constant voltage (CV) mode. The digital control loop maintains setpoint stability within 1%, ensuring process repeatability for critical EC reactions.
Built-in Polarity Reversal: Standard feature. Operators can set automatic polarity reversal intervals (from seconds to hours) to actively de-scale electrode plates and prevent passivation, dramatically reducing maintenance downtime.
Robust Mechanical Construction: Housed in a sealed, corrosion-resistant steel cabinet with a clear protective coating. All electronic assemblies are isolated from process fumes and moisture.

Part 3 Advanced Built-in Protection Systems
This unit is equipped with comprehensive safeguards to protect both the power supply and the treatment process. The system automatically triggers a safety shutdown upon detection of: Over-Voltage (OVP), Over-Current (OCP), Over-Temperature (OTP), or Short Circuit. A dedicated internal arc suppression circuit prevents damage during electrode sparking, a common phenomena in EC cells.
Part 4 Target Industrial Applications
Industrial Wastewater Treatment: Primary application for electrocoagulation (EC) and electro-flotation (EF) systems targeting oil emulsions, dyes, and heavy metals.
Mining & Hydrometallurgy: Ideal as a high-current rectifier for electrolytic extraction and metal recovery from mining process water.
Electrochemical Cleaning: Powering electro-etching and electro-cleaning baths for metal surface preparation prior to coating or anodizing.
