Product Description

Application: Control & Protect three phase pump, DOL

Our special design makes it a very reliable and sensitive protection against pump dry running without installation of any probe/sensor in the deep well.

Main Features:

Built in function switch:
Applied for water supply by liquid level control or booster
Applied for drainage by liquid level control
- Auto / Manual switch
- Starts and stops the pump in accordance with the different liquid level or pressure setting.
- Push Button Calibration
- Automatically stop the pump in the case of water shortage, protecting it from drying running
Without installing the float switch or liquid probe in the well
- Pump accumulative running time displaying
- Pump last five fault record displaying
- LCD displays pump running information
- Protect the pump against Over /Under Voltage; Over Current; Pump Shaft Rust; Rapid
Cycle ,Open phase ,phase reversal,phase unbalnced protection .
- Grade of Protection IP 54
- Visual & Audio alarm for fault prompt
- Present remote monitor
