The 12V 4000A Hydrometallurgy 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.
Working-point focus: the nameplate rating is an available ceiling, not a recommended operating recipe. The normal working current and voltage must come from the validated process window and actual load.
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
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.
