VARIOspeed® MICRO Series

Variable Frequency Drive

The VARIOspeed® MICRO Series VFSs are a pre-engineered variable speed option for constant pressure applications.

The VARIOspeed® MICRO Series VFDs are an economical, pre-engineered variable speed option for constant pressure control applications using a single factory-programmed variable frequency drive for easy installation and set up.  With single phase 230 VAC input, these VFDs offer selectable 230 VAC single phase or three phase output, making it an excellent option for your indoor applications!

As flow and head conditions change in the pumping system, the VARIOspeed® MICRO VFD automatically controls the pup and maintains a constant discharge pressure.  The desired set pressure is set on the VFD keypad.  The pressure transducer measures the pump discharge pressure.

For use in deep well submersible and centrifugal pump applications.
