PowerFlex DC Drives

The PowerFlex® DC drive (20P) provides digital control for precise speed and current regulation, easy programmability, extensive diagnostics, and
non-regenerative or regenerative operation. PowerFlex DC drives can run various applications, including extruder operations, finishing, drawing,
and coating. The PowerFlex DC drive can effectively control applications that exhibit shock loads, high inertia, rapid acceleration and deceleration
rates, or continuous regeneration. These features of the PowerFlex DC drive make it an excellent choice for existing DC machinery upgrades. The
compact design of this drive includes a fully contained power module and a common control structure for the entire range of horsepower. And, to
make connectivity even easier, the PowerFlex DC drive provides a standard DPI™ interface that is compatible with all PowerFlex DPI
communication products.
The standard hardware consists of an open type enclosure, armature converter, regulated field converter for field weakening or economy
applications, and an advanced regulator with integrated DPI functionality. The standard I/O includes eight digital inputs, four digital outputs,
three analog inputs, two analog outputs, a DC tachometer, and encoder capability.
Note: Optional I/O and feedback modules are available and are sold separately from the standard hardware offering. For more information, see I/O Option Kits and Feedback Option Kit (only for PowerFlex DC drives)

The PowerFlex DC Field Controller
The PowerFlex DC Field Controller provides three-phase, four quadrant (reversing) DC motor or generator field control. The PowerFlex DC Field
Controller can be used for standalone DC motor field control applications or with a PowerFlex DC Digital drive or PowerFlex DC Standalone
Regulator (SAR). A fiber-optic interface option module or digital and analog I/O provides transmission of the reference, feedback, and status
signals between the drive or regulator and the field controller.
In the standalone mode, the PowerFlex DC Field Controller provides power to a DC motor field with a fixed reference by using fixed I/O. The
PowerFlex DC Field Controller can also be used to supply various DC non-motor loads (highly inductive loads) such as galvanic applications,
electromagnets, synchronous motor excitation circuits, and more.
A PowerFlex DC field controller is a cost-effective way to modernize DC motor controls while using/re-purposing existing equipment.
Controller Features
• Programming flexibility allows parameters to be linked within the device.
• Field-flashable firmware through DPI interface.
• Reversing field supply standard on all frames.
• Control non-motor inductive loads, such as electromagnets
The PowerFlex DC Standalone Regulator
The PowerFlex DC Standalone Regulator (SAR) and Gate Amplifier products provide an integrated solution to control external DC power
modules. The SAR is a DC drive regulator that provides armature regulation, armature SCR gate signals and a regulated field supply. The SAR field
supply consists of a single phase, two quadrant (non-reversing,) full wave rectified bridge, available as 40 or 70 amps. The SAR supports an AC line
input voltage range of 230…690V AC and a field input voltage range of 100…460V AC.
