The 12V 4000A Metal Electrolysis Rectifier is a unidirectional DC power supply rated at 12 V and 4000 A for metal electrowinning and recovery 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 | 12 V DC, 4000 A DC |
|---|---|
| Application | metal electrowinning and recovery |
| 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 deposition of a defined metal onto cathodes from a process solution Use cathode area and current density or a Faraday production route with confirmed efficiency and operating time. Confirm total loaded voltage from chemistry, cells, connection, spacing, overpotential and busbar losses.
The target metal and whether the process is electrowinning or electrorefining must be confirmed.
Control focus: describe the required operating sequence and external interlocks in writing. Timers, ramps, analog control and communications are project options rather than assumed standard functions.
Information Required for Selection
- target metal and process route
- electrolyte composition
- electrode materials and area
- current density
- cell count and connection
- production target and efficiency
- loaded voltage and busbar loss
- duty and harvest cycle
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.
