15V 1500A Surface Anodizing DC Power Supply

The 15V 1500A Surface Anodizing DC Power Supply is a unidirectional DC power supply rated at 15 V and 1500 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	15 V DC, 1500 A DC
Application	aluminum anodizing
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 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

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.
