Inverter for Deep Well Submersible Pump Control (Wall Mounted Type)
WPMS-7000 Series | Water Pump Management System
Summary
The SubCon Controller Provides a state-of-the art solution for water well applications. The water pressure is monitored continuously and the SubCon VFD will automatically adjust the pump speed to maintain constant pressure.

Key Functions
- 1. Shallow Well Operation(selectable)
- The drive will stop on low level(under current) and automatically re-start after a Programmable set time without generating a fault.
- 2. Low Voltage operation(selectable)
- During low voltage conditions, the Amp load of the pump will increase and could Potentially trip the VFD on overload. The SubCon is able to recognize this Condition and automatically reduce the motor speed and avoid trip pin.
- 3. Digital Input
- A digital input is available in the SubCon Drives for monitoring a potential free contect.
An external stop switch, pressure switch, or float switch could be used to stop the drives operation. - 4. Relay Outputs
- 1 relay output is available for pump alarm status.
