VFD Controllers

Showing all 5 results

Variable frequency drives, also known as VFD controllers, are motor controllers that drive electric motors by changing the voltage and frequency of the power supply. They are great for saving energy and improving efficiency within a system. They can also convert power in hybrid applications while integrating networking and diagnostics. Big Bear Instruments offers a variety of Variable Frequency Drives.  These cost effective VFD controller solutions are easily configured and offer a wide range of programming capabilities. Sort by manufacturer, series, or working voltage to find the best match for your application. Check out our selection of VFD controllers today and find the right one for your application.

  • Unitronics UMI-B1 Series UL Variable Frequency Drives

    Unitronics Variable Frequency Drives (also known as VFDs) are designed to optimize machine performance, save energy, and lower machine life cycle costs across a range of applications.  VFDs can be used as a stand-alone product or integrated with other Unitronics controllers making them an all-in-one application.  With the option of integrating, users can operate the VFD directly from the controller’s HMI panel using the same programming software as the PLC control and HMI application. Doing so will allow for set-up and/or configuration of multiple VFDs in a snap.  In addition, integration allows for monitoring and debugging the VFD, either via UniLogic or Scope Trace, and remotely accessing the VFD via UniLogic.

    The UMI-B1 Series UL offers single phase or three phase input voltage.
