3. Constuction
Control unit for a single-phase submersible pump.
Functions are controlled from the PFC-M
electronic control panel, which reads the power
factor (PF) for protection against dry functions,
without installing the level probe in the well.
The PFC-M control panel enables setting:
- The motor rated power
- The PF alarm limit
- The minimum and maximum limits for power
voltage
- Programming 4 restarts for the pump when there
is no water
- The pump working times and the stops if there is
no air in the tank (patented system).
Materials
