The 30V 15A Industrial Anodizing Rectifier is a unidirectional DC power supply rated at 30 V and 15 A for aluminum anodizing 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 | 30 V DC, 15 A DC |
|---|---|
| Application | aluminum anodizing |
| 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 electrochemical formation of an oxide film under a defined alloy, electrolyte and coating specification Estimate current from I = J × A using maximum effective anodized area and the current density for the exact anodizing process. Confirm starting and maximum process voltage because alloy, electrolyte, temperature, spacing and film growth affect the required voltage.
Conventional anodizing, hard anodizing and PEO are separate process branches and must not share one operating recipe.
Voltage-loss focus: include electrode gaps, busbars, cables, contacts, fixtures and electrolyte or load resistance when checking loaded voltage. Excess voltage margin can increase heat without improving the process.
Information Required for Selection
- anodizing branch and electrolyte
- alloy and workpiece area
- current density
- target film thickness
- cycle time and temperature
- starting and maximum voltage
- ramp or current program
- bath cooling and duty
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.
