Description and Features
The Franklin Electric SubDrive300 is a dependable residential and light
commercial water system controller that uses advanced electronics to
enhance the performance of standard submersible pumps. When used with
the specified Franklin Electric motor (see Table 1), the SubDrive eliminates
pressure cycling associated with conventional water well systems and
owners of private water well systems can enjoy “city-like” water pressure.
In addition, the reduced tank size (see Table 3) allows installation in small
spaces. Key features of the SubDrive include:
• Constant water pressure with a wide range of settings (25-80 psi)
• Smaller pressure tank can be used
• Fits the pump to the application – pump speed is controlled to
provide the optimum performance without overloading the motor
• Flexibility – you can use this unit with standard off-the-shelf pumps
• No in-rush (power-on transient) current
• Low motor start-up current (soft-starting)
• Active Power Factor Correction minimizes input RMS current
• Protection features
- Dry well conditions – using smart pump monitoring (see Page 26)
- Bound pump – with auto-reversing torque
- High voltage / lightning surge
- Low line voltage
- Open motor circuit
- Short circuit
