The Franklin Electric SubDrive Utility UT3P is a variable frequency drive (VFD) designed to control and protect 3-wire, single-phase 230V motors, and 3-phase 230V motors, enhancing pump performance for residential and light commercial water system applications. When used with Franklin Electric motors ranging from 1/2 to 2 HP, the UT3P drives a pump - motor assembly at variable speeds to maintain constant water pressure, even as user demands (water flow) change.

The drive is designed to convert a conventional pump system to a variable speed constant pressure system by simply replacing the pressure switch and control box.
