Simple and cost-effective DC field controller for retrofittingRockwell Automation’s new Allen-Bradley PowerFlex DC field controller enables customers to upgrade their DC motor application to a modern system, without the need for complex external devices. An up-to-date digital networked control system helps customers gather and leverage vital information throughout their enterprise.

The DC field controller provides three-phase, four-quadrant (reversing) DC motor or generator field control. The field controller can be used on its own or with a PowerFlex DC digital drive. In stand-alone mode, it provides power to a DC motor field with a fixed reference by using fixed I/O. The field controller can also control electromagnets and other non-motor loads.

Nancy Rivard, product manager for Rockwell Automation says: “For DC retrofit applications that require motor reversing, the PowerFlex DC field controller helps eliminate the need for an additional armature bridge or a complex system of external devices, saving customers both time and money. Having a single source for all automation equipment – including both AC and DC drives – also simplifies machine startup, operation and maintenance.”

The field controller offers output ratings from 17A to 575A and input of 200V and 500V. It enhances the capability of the PowerFlex DC drive family, designed for demanding stand-alone and coordinated drive system applications. The PowerFlex DC drive family is well suited for DC motor applications and retrofits up to 6000Hp or 4000kW.

The PowerFlex DC family has core capabilities aligned with the PowerFlex AC family of drives, including seamless integration into a Logix-based environment, flexible feedback and communication options, as well as voltage settings designed to global standards.
