60V 800A Membrane Desalination Rectifier

The 60V 800A Membrane Desalination Rectifier 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.

Load-data focus: selection should start with effective area, cell or stack arrangement, chemistry and the maximum simultaneous production load. A product name alone is not enough for final sizing.

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

Is the rated current the normal process current?

No. The rating is the product ceiling; the working setpoint must follow the validated process window and actual load.

Can the process name determine the final voltage?

No. Loaded voltage depends on chemistry or load behavior, spacing, contacts, conductors and the production arrangement.

Are pulse, reversal and communications included?

Only when they are written into the confirmed configuration. They are not assumed from the product title.
