60V 40A Hard Coat Anodizing Power Supply

The 60V 40A Hard Coat Anodizing Power Supply is a unidirectional DC power supply rated at 60 V and 40 A for hard 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	60 V DC, 40 A DC
Application	hard 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 engineering hard-coat anodizing for a defined aluminum alloy, film thickness and production cycle Use effective area and the hard-anodizing current density supplied by the validated process; check the maximum production load. Voltage commonly rises as the oxide film grows, so the start point, maximum voltage and approved ramp must be confirmed.

Hard anodizing is not the same as conventional decorative anodizing or plasma electrolytic oxidation.

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

• aluminum alloy
• effective area and load
• hard-coat chemistry
• current density
• target thickness and cycle
• starting and maximum voltage
• ramp profile
• bath temperature, 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.
