24V 2000A Rectifier for Aluminum Anodizing

The 24V 2000A Rectifier for Aluminum Anodizing is a unidirectional DC power supply rated at 24 V and 2000 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	24 V DC, 2000 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.

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

• 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

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.
