The 30V 2000A Wastewater Treatment DC Power Supply 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.
Scale-up focus: use pilot results or reliable data from the existing line, then scale by the true area, cell count and maximum production condition. Do not scale from tank volume alone.
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
Why can working voltage be below the rated voltage?
The rated value provides an operating envelope. The actual requirement is the loaded process voltage plus verified conductor and contact losses.
Can AC input be selected from DC current alone?
No. DC voltage and current determine output power, and the site supply, phase and frequency must also be confirmed.
Does the page guarantee a particular process result?
No. Process results also depend on chemistry, materials, geometry, preparation and the validated operating recipe.
