The 15V 1000A Electrolytic Polishing Rectifier is a unidirectional DC power supply rated at 15 V and 1000 A for electropolishing 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, 1000 A DC |
|---|---|
| Application | electropolishing |
| 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 controlled anodic material removal for a defined metal, electrolyte and surface target Estimate current from effective workpiece area and the current density approved for the exact material and bath. Confirm loaded voltage from material, electrolyte, temperature, spacing, fixtures and busbar losses.
In conventional electropolishing the workpiece is the anode; values for one material must not be transferred to another.
Scale-up focus: use pilot results or reliable data from the existing line, then scale by the true area, cell count and maximum production condition. Do not scale from tank volume alone.
Information Required for Selection
- workpiece material
- electrolyte and temperature
- effective area
- current density
- operating voltage
- removal and finish target
- cycle time and electrode layout
- ventilation, duty and site conditions
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
Why can working voltage be below the rated voltage?
The rated value provides an operating envelope. The actual requirement is the loaded process voltage plus verified conductor and contact losses.
Can AC input be selected from DC current alone?
No. DC voltage and current determine output power, and the site supply, phase and frequency must also be confirmed.
Does the page guarantee a particular process result?
No. Process results also depend on chemistry, materials, geometry, preparation and the validated operating recipe.
