SubDrive Connect

The SubDrive Connect Variable Frequency Drive is a constant-pressure drive for residential and light commercial water systems, optimized for submersible and above-ground pumps from 1/2 to 5 hp.

• Constant pressure performance for residential and light commercial water systems, eliminating noticeable pressure fluctuations at faucets and fixtures.

• Designed specifically for water pumping applications to maximize reliability and efficiency in well and booster pump installations.

• Supports submersible and above‑ground pumps with single‑phase, two‑wire and three‑wire, or three‑phase motors, giving installers broad application flexibility.

• Soft‑start technology that reduces mechanical stress on the pump, motor, and plumbing, helping extend total system life.

• Advanced filtering that mitigates interference with sensitive electronic devices such as LED lighting and smart home equipment.

• Power factor correction to optimize performance across a wider operating range and improve overall energy use.

• Built‑in dry‑run (underload) protection with adjustable sensitivity and off time to help protect the well and pump.

• Integrated protection against overload/locked pump, broken pipe conditions, output short or open circuit, undervoltage, electrical surge, and overheated controller.

• Moisture sensor input plus run and fault relays to enhance system monitoring and safety.

• Easy installation using basic DIP switches for setup, with no complex programming required for standard constant pressure systems.

• Onboard LCD display providing clear, real‑time readouts for pressure, status, and fault information to speed startup and service.

• FE Connect mobile app compatibility for real‑time local monitoring, configuration, advanced settings (frequency range, lead/lag/alternation, broken pipe detection), and fault log retrieval from a smart device.

• One‑to‑One support feature that lets you temporarily share live system data with off‑site experts or Franklin Electric technical support for faster troubleshooting.

• Ideal for new construction or retrofits, including systems using small pressure tanks or existing larger tanks.

• Compact, wall‑mountable NEMA 3R enclosure suitable for indoor or outdoor installation, with protection against falling rain or sleet.

• Available as a standalone drive or as part of the SubDrive QuickPAK package that bundles pump, motor, and drive in one solution.

• Built‑in lead/lag and alternation capability for duplex pumping systems.

• Standard I/O ports for streamlined integration with adjacent controls and monitoring equipment.

• Fully supported by Franklin Electric’s technical support professionals and field service engineers for long‑term peace of mind.
