The 12V 50A Gold Electroplating DC Power Supply is a unidirectional DC power supply rated at 12 V and 50 A for gold electroplating 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, 50 A DC |
|---|---|
| Application | gold electroplating |
| Regulation | Constant-current or constant-voltage main mode, selected for the confirmed process |
| AC input | AC 220 V or 380 V; AC 415 V can be evaluated as a site option. Final phase and frequency 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 gold or gold-alloy deposition for a defined soft-gold, hard-gold, flash, thick-deposit or electroforming objective Use effective energized area and the current-density window from the exact chemistry; soft gold, hard gold, flash and thick deposits are not interchangeable. Confirm loaded cell voltage from chemistry, contacts, spacing, selective electrodes and connection losses.
Soft gold, hard gold, flash gold and thick gold use different chemistry and process windows; the exact deposit must be defined.
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
- metal or alloy
- chemistry supplier and product
- substrate and underplate
- coating purpose and thickness
- effective area and load
- approved current density
- rack, barrel, selective or continuous method
- waveform and traceability 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
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.
