The 12V 1000A IGBT Rectifier for Hard Chrome is a unidirectional DC power supply rated at 12 V and 1000 A for hard chrome electroplating 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 | 12 V DC, 1000 A DC |
|---|---|
| Application | hard chrome electroplating |
| 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 industrial hard chromium deposition for a defined substrate, coating thickness and production load Calculate current from the effective plated area and the hard-chrome current density approved for the bath and workpiece. Hard chrome voltage depends on conductivity, temperature, anode spacing, fixtures and busbar losses; verify the maximum loaded tank voltage.
Hard chrome must be separated from decorative chrome because coating objective, thickness and operating window differ.
Control focus: describe the required operating sequence and external interlocks in writing. Timers, ramps, analog control and communications are project options rather than assumed standard functions.
Information Required for Selection
- hard chrome rather than decorative chrome
- substrate and coating objective
- effective plated area
- current density and process time
- target thickness
- loaded tank voltage
- anode and fixture arrangement
- duty and installation environment
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.
