Intelligent Digital Single Phase Deep Well Pump Control Box - Auto ,Black Color ,One Button Calibration.

 

Main Technical Specifications

 

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.

① Percent of rated input voltage ( i.e if the rated input voltage is 220V, the Over voltage trip

is 253V, the Under voltage trip is 187V)

② Percent of load time of calibration(i.e if the output power of pump motor is 1kw during

the calibration, the under load (Dry running ) trip is 0.75kw ,the Over load trip is 1.25kw)

③ Percent of load time of calibration load (i.e if the output power of pump motor is 1kw during

the calibration, the pump stalled trip is 2kw)
