Alternating Current Power Supply (AC)


When it comes to the Colouring of Aluminium special alternating current power supplies (AC Devices) are used.

Product Description:

The AC Device is mostly offered in oil-cooled design. For applications that call for relatively low currents the air-cooled version would be also possible. Due to the robust enclosure (IP 54) which is filled with insulating oil an installation in direct proximity to the tank is possible. By means of a special control unit different standard colours can be produced according to EUPAS.

Block Diagram / Functional Description:

The necessary control unit is featured with an individual ramp function as well as  several timing elements to produce different colour shades.

Customer Benefits:

Because of its robustness and easy handling the AC Device in oil cooling offers an attractive entrance for E-Coating Processes. A special control allows reproducible surface results. For individual use and respective surfaces we would recommend the power supply DCAC 100.
