Series 70 AutoCoat MAC Rectifier


Our Series 70 AutoCoat rectifier has a front access, single transformer, secondary thyristor design, which can be used as both a standalone rectifier or in a Modular Anode Control (MAC) system. Offered in two (2) models, the “Model 706” (utilizing a 6-pulse SCR configuration) and the “Model 7012” (utilizing a 12-pulse SCR configuration), the Series 70 AutoCoat is available with DC output ratings of 400V – 450V and 200A – 400A.

Compatible with today’s advanced e-coat processes, the Series 70 AutoCoat rectifier is specifically designed for automotive and general e-coat applications which require greater voltage and current control of each anode. Designed for optimum, reliable performance in harsh industrial environments, the Series 70 AutoCoat rectifier is an ideal choice for MAC e-coat applications, as well as smaller single rectifier systems.

  • Does the Series 70 AutoCoat offer PLC control and monitoring?

  • Yes! The Series 70 AutoCoat may be provided with internal I/O modules, which allow communication with a centralized PLC that digitally controls the rectifier (e.g., in a MAC system). Provided by Controlled Power Company or others, this PLC may also communicate with a plant’s centralized monitoring system. The PLC instructs the rectifier(s) at which voltage level to operate; and monitors both the voltage and current output of the rectifier(s), as well as any alarm conditions. The PLC’s programming can also be customized to whatever type of control and monitoring is desired for the system.

  • How can I reduce the floor space needed for rectifiers used in my process?

  • Controlled Power Company is able to custom design rectifier cabinets for limited floor space or single side access. We are also able to provide multiple rectifiers in a single enclosure.
