The 60V 800A Membrane Stack Power Supply is a unidirectional DC power supply rated at 60 V and 800 A for electrodialysis 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 | 60 V DC, 800 A DC |
|---|---|
| Application | electrodialysis 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 DC supply to an ED membrane stack for desalination, concentration or ionic separation Use membrane-stack current density and effective membrane area; determine total current from the actual stack and electrical connection. Use the membrane-stack design sheet or polarization curve because membrane pairs, solution resistance, temperature and concentration change total voltage.
ED, EDR, EDI and BPED are different systems; polarity reversal and valve sequencing are not standard ED assumptions.
Voltage-loss focus: include electrode gaps, busbars, cables, contacts, fixtures and electrolyte or load resistance when checking loaded voltage. Excess voltage margin can increase heat without improving the process.
Information Required for Selection
- ED, EDR, EDI or BPED route
- membrane brand and stack model
- effective area and membrane pairs
- working current density
- stack voltage limits
- stack series/parallel connection
- feed conductivity, flow and temperature
- reversal, interlock and control 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.
