Series 70 AutoCoat MAC Rectifier

Industrial DC Power Supplies (Rectifiers)

Description:

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 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.

  • Can the Series 70 AutoCoat be used in a 1- or 2-zone standard e-coat system configuration?
    • Yes! The Series 70 AutoCoat is available in a standard model, which has controls for a conventional monorail or batch type e-coat configuration, plus a single-output bus for connection to multiple anodes.
  • Does the Series 70 AutoCoat offer PLC control and monitoring?
    • Yes! The Series 70 AutoCoat may be provided with internal distributed I/O modules, which allow communication with a PLC that digitally controls and monitors multiple rectifiers at one time (e.g., in an MAC system). Whether provided by Controlled Power Company or another manufacturer, this PLC can also communicate with a manufacturing plant's PLC or centralized monitoring system for expanded monitoring and control.
  • Do I need a separate anode monitoring system in an MAC system with the Series 70 AutoCoat?
    • No. The Series 70 AutoCoat has built-in current sensing for each output that is connected to the tank. The current values can be sent either over Ethernet / Serial connections with distributed I/O or analog 4-20mA signals.
  • How can I reduce or eliminate downtime?
    • Purchasing and installing a second backup rectifier connected in parallel with the existing rectifier and a DC switch, will virtually eliminate downtime. In this scenario, if a rectifier happens to go down or is being serviced, a backup unit can be brought online within a few minutes. For more information, see our Options document entitled "DC Transfer Switches" for details about DC switch and backup rectifier configurations.
  • 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.

AACD

The Automatic Average Current Density (AACD) is an available voltage control option with this E-Coat rectifier. Based upon the size of the part being painted, the AACD automatically adjusts the DC voltage (throw power) in order to control the amount of paint applied to the part. The result is that over-coating and under-coating are reduced or eliminated; thus saving money related to excess paint usage and rework costs. For additional product and application details, please visit our AACD webpage!

Warranty

Controlled Power Company warrants the Series 70 AutoCoat MAC Rectifier to be free from defects in material and workmanship for a period of one (1) year following shipment from the factory. Controlled Power Company agrees to replace, F.O.B. its factory, any parts which fault through defect in material or workmanship during the warranty period.

Consult the factory for additional warranty details, and a description of start-up services provided.
