Rockwell Automation introduced its new Allen-Bradley PowerFlex DC field controller, designed to help enable customers to upgrade their DC motor application to a more modern system without the need for more complex external devices. An up-to-date digital networked control system can help customers gather and leverage 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.
The field controller offers output ratings from 17 amps to 575 amps and input of 200-volts and 500-volts. It helps to enhance the capability of the PowerFlex DC drive family, designed for either stand-alone and coordinated drive system applications. The PowerFlex DC drive family is suited for DC motor applications and retrofits up to 6,000 Hp or 4000 kW.
The PowerFlex DC family has core capabilities aligned with the PowerFlex AC family of drives, including integration into a Logix-based environment, more flexible feedback and communication options, as well as voltage settings designed to global standards.
