AACD (Automatic Average Current Density)
The AACD (Automatic Average Current Density) is an automatic rectifier voltage controller designed to precisely regulate current density during the e-coat electrocoating process. By controlling current density at the part level, AACD ensures consistent paint film thickness, even when mixed part sizes enter the tank at different times.
AACD automatically adjusts rectifier voltage to maintain the correct average current density on the parts being painted. This results in a narrower film thickness range, improved coating uniformity, and a more efficient overall process – whether operating in a continuous conveyor or batch environment.

FAQs
How much can I save with the AACD?
We have seen savings of up to $50,000 per year and in one case even $1,000,000 per year. (Note that savings depend upon system configuration and volume of parts.)
What improvements are achieved by using the AACD?
- Paint Savings: Variations are reduced to about +/- 0.1 mil or +/- 2.5 microns of target film builds.
- Energy Savings: The ability to control the rectifier voltage and eliminate over-coating results in less energy consumption during the e-coat process.
- Labor Savings: Automatic voltage control eliminates the need to manually adjust the voltage during the e-coat processes.
- Quality Improvements: Rework costs are drastically reduced, if not eliminated.
Does the AACD require a part detection system?
No. The AACD uses proprietary software to set voltage levels based upon current levels in the paint tank.
Will the AACD work with any rectifier manufacturer?
Yes! The AACD is a universal product which can be wired to control any adjustable DC power supply.
Can the end user program the AACD?
Yes. The AACD can be programmed by the end user via a touch screen display. A technician from the factory is not required.
What tolerances on film build can I expect to achieve with the AACD?
There are many factors to consider. However, if groups of parts are loaded fairly consistently, then the AACD can achieve film build tolerances to within 0.1 mil or 2.5 microns.
What is required for AACD Installation?
- Hardwired 120V or 220V single phase source, 5A.
- Approximately 15 signal wires (16 awg or 18 awg), and one must be shielded (rectifier and configuration dependent).
- Conduit for signal wires running from the AACD enclosure to inside the rectifier.
- A Controlled Power Company technician to perform the internal wiring of the rectifier and the initial setup of the system.
