DC Drives Combine Performance, Integration

The new Allen-Bradley PowerFlex DC drives from Rockwell Automation combine the powerful performance capabilities of DC technology with the added benefits of digital control, diagnostics, programming and system integration through the communication options inherent in the PowerFlex drive architecture. The compact design of the PowerFlex DC drives make them suitbale for a variety of demanding standalone or coordinated drive control and drive system applications.

Available in 1.5 Hp to 150 Hp @ 230VAC and 2 Hp to 400 Hp @ 460VAC, the PowerFlex DC drives feature analog and digital I/O options for installation while the PowerFlex drive peripheral interface (DPI) allows connectivity to a variety of communication adapters and programming tools.

Regenerative and non-regenerative DC drive configurations are available. The PowerFlex DC drives feature an LCD human interface module which helps simplify drive configuration and tuning, while pull-apart control terminal blocks allow for quick wiring and quick disconnect.

Software connectivity through PowerFlex DPI allows connectivity to a common set of DPI-based host products, including communication adaptors, operator interfaces and software tools.

DC tachometer and encoder feedback capabilities are embedded into the control circuitry as a standard feature, which to help save space and provide functionality. The PowerFlex DC drives offer diagnostics and are interfaced for integration into larger drive systems.

Users can program, monitor and control the drives using Allen-Bradley DriveExplorer and DriveTools SP software suite.

For applications requiring DC drives mounted on a wall, an existing cabinet or in MCC cabinets, the PowerFlex DC drives are available in preconfigured packages to meet a range of application requirements. Drive enclosures can be sized and designed to meet most IP/NEMA/UL protection requirements.
