Intelligent Three Phase Water Pump Control Panel - Auto And Manual,0.75-15KW

Model: L932

 

Products Brief :

 

L931 is applied for automatic liquid level control / pressure control and effective protection for single pump of with AC220V, 50hz, single phase output power 0.75KW-15KW (1HP-20HP),direct start, including stainless steel or cast iron submersible pump,centrifugal pump, sewage pump etc.

 

Model L931 has many operation modes by adopting different electric installations. An important feature that makes the difference between Model L931 and common On/Off pump control box is the probe / sensor free in the well. Our special design makes it a very reliable and sensitive Protection against pump dry run without installation probe / sensor in the well.

 

Model L931 is useful in all cases we need to control and protect single pump managing its turn-on and turn off by different electric installations.

 

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

① the Characteristic of Inverse-time, the stronger of the current, The shorter of trip response time)

 

② Percent of rated input voltage ( i.e if the rated input voltage is 380V, the Over voltage trip is 437V, the Under voltage trip is 323V)

 

③ Percent of load time of calibration ( i.e if the running ampere of pump motor is 10A during the calibration, the dry running trip ampere is 7A)

 

④ Percent of load time of calibration ( i.e if the running ampere of pump motor is 10A during the calibration, The pump stalled trip ampere is 20A)
