Intelligent Single Phase Water Pump Controller - Auto , Black Color ,LCD Displaying


Pump Control Box model M921 measures the actual motor power (watts), not motor amps or power factor. The motor power draw at the moment of calibration is permanently memorized by M921. If the calibration power by more than ±25%, M921 will turn off the pump motor.This special layout makes it possible to realize the sensitive and reliable function of stopping protection against pump dry running without installing lower water tank (well) sensor, which makes it more convenient and economical to install deep-well submersible pump and pipeline pump.


Typical usage scenarios include:
-Houses
-Flats
-Holidays houses
-Farms
-Water supply from wells
-Irrigation of greenhouses, gardens, agriculture
-Rain water reuse
-Industrial plants
-Waste water tank / Sewage sink
