PRODUCT INFORMATION
Description
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 commercial water system applications. When used with Franklin Electric motors ranging from 1/3 to 1
½ 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 also compatible with single-phase 2-wire submersible
split capacitor (PSC) motors, above-ground booster pumps, and jet pumps
with overload current ratings from 4.6 A to 13.1 A.
*
The SubDrive Utility is designed to convert a conventional pump system to a
variable speed constant pressure system by simply replacing the pressure
switch.
