The Franklin Electric SubDrive Utility is a variable frequency drive (VFD) designed to control and protect 2-wire, single-phase motors with 115 or 230 volt ratings, enhancing pump performance for residential and light commerical water system applications. When used with Franklin Electric motors ranging from 1/3 to 1 1/2 HP, the SubDrive Utility drives a motor and pump at variable speeds to maintain constant water pressure, even as user demands (water flow) change.

The SubDrive Utility is designed to convert a conventional pump system to a variable speed constant pressure system by simply replacing the pressure switch.
