Franklin Electric’s SubDrive UtilityTM Variable Frequency Drive converts 2-wire conventional submersible pumping systems, ranging from 1/3 hp up to 1-1/2 hp, along with 115 V and 230 V single-phase 2-wire submersible PSC, above-ground booster, and jet pumps with overload current ratings from 4.6 A to 13.1 A, into constant water pressure systems. Designed with a compact footprint, it features a sleek NEMA 3R enclosure rated for both indoor and outdoor use, and retrofits to most pumping systems utilizing a Franklin Electric motor. Separate of the pump and motor, the drive makes troubleshooting and maintenance of the pumping system significantly easier compared to all-in-one units.Features One unit is compatible with 115 and 230 volt Franklin Electric 2-wire motors Provides constant pressure and motor/pump protection in a small and robust package User-defined underload protection, and several pressure control adjustments, to fit a wide range of pumping applications Motor soft-start reduces inrush current during starts for longer motor life Robust SubDrive pressure sensor standard for ease of installation Additional input for optional analog pressure transducer for precise pressure control No programming required with easy DIP switch setup Three LED indicators allow for easy identification of system status and troubleshooting USB port allows for easy firmware updates UL and cUL listedm1774_subdrive_utility_spec_sheet.pdfM1330-Control-Boxes-03-09.pdf
