The 15V 3000A Silver Refining DC Power Supply is a unidirectional DC power supply rated at 15 V and 3000 A for precious metal refining 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 | 15 V DC, 3000 A DC |
|---|---|
| Application | precious metal refining 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 recovery or refining of a specified precious metal under a defined chemistry Use electrode area/current density or a Faraday production calculation with verified valence, efficiency and operating time. Confirm cell voltage from chemistry, electrode arrangement, concentration and connection losses.
Gold, silver and platinum-group recovery routes are not interchangeable, and electrowinning must be separated from electrorefining.
Production-window focus: size against the credible maximum load while preserving useful adjustment through normal production. Minimum, normal and maximum conditions should be supplied together.
Information Required for Selection
- target metal and recovery route
- feed and electrolyte
- electrode materials and area
- current density
- cell count and connection
- production/recovery target
- current efficiency and loaded voltage
- 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
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.
