30V 2000A DC Supply for EC Treatment

The 30V 2000A DC Supply for EC Treatment is a unidirectional DC power supply rated at 30 V and 2000 A for electrocoagulation water treatment projects. The published rating defines the available DC envelope; it does not replace process calculations or establish the normal operating setpoint.

Published Rating and Electrical Boundary

Rated DC output	30 V DC, 2000 A DC
Application	electrocoagulation water treatment
Regulation	Constant-current or constant-voltage main mode, selected for the confirmed process
AC input	AC 380 V or 415 V. Final phase, frequency and site conditions must be confirmed.

This product follows Gao Hui’s low-voltage AC input, high-frequency switching and isolation, one-way DC architecture. It is not presented as an external DC-input converter, AC-output source, bidirectional or regenerative supply, or medium/high-voltage direct-input system.

Application and Selection

This page applies to electrochemical generation of coagulant from iron, aluminum or combined electrodes in a defined reactor Calculate current from effective electrode area and the trial-approved current density; flow alone is not a valid ampere selection method. Confirm the highest cell voltage from water conductivity, pH, temperature, electrode spacing, connection and electrode ageing.

Electrocoagulation differs from electrocatalytic oxidation and requires its own electrode consumption and reactor design data.

Quotation focus: a technically comparable quotation needs the DC working range, site AC supply, duty, installation environment and required controls. Missing items will be marked for confirmation.

Information Required for Selection

• wastewater and target pollutants
• flow, batch volume and residence time
• electrode material and area
• current density
• electrode spacing and connection
• pH, conductivity and temperature
• trial current and voltage
• cleaning, duty and safety requirements

Also provide the site AC voltage, phase and frequency; cable distance; daily duty; ambient conditions; cabinet location; required local or remote control; and any interface or interlock list. Gao Hui engineering can then check the practical working range against the published rating.

Configuration Boundary

The confirmed standard scope is limited to the published DC rating and stated process use. Cooling method, enclosure, control interface, ramp, timer, ampere-hour control, pulse waveform, polarity reversal, communications, ripple target and redundancy are project-specific. They are supplied only when written into the confirmed configuration and must not be inferred from a legacy title, image or category.

Frequently Asked Questions

How should this rectifier be sized?

Provide the maximum effective load, accepted current-density or load data, loaded voltage, duty and site AC supply.

Can one rating be used for every line?

No. Lines with the same process name can have different areas, connections, resistance and control sequences.

Is cooling fixed by this page?

No. Cooling and enclosure are selected after duty, ambient conditions and installation details are reviewed.
