Detailed Product Description
Phase: | Single Phase | Pump Controlled Quantity: | One Pump |
Enclosure Protection Grade: | IP54 | Displaying: | LCD Display |
Liquid Level Transfer Distance: | ≤1000m | Unit Dimensions ( L X W X H): | 30.2 X 24x 12cm |
Products Brief :
L921 is applied for automatic liquid
level control / pressure control and effective protection for duplex pumps of with AC220V, 50hz, single phase output power 0.37 to 4kw (0.5hp-5.5hp),direct start, including stainless steel or cast iron submersible pump,centrifugal pump, sewage pump etc.Model L921 has many operation modes by adopting different electric installations. An important feature that makes the difference between Model L921 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 L921 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
Irrigations 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 220V, the Over voltage trip is
253V, the Under voltage trip is 187V)
③ Percent of load time of calibration ( i.e if the running ampere of pump motor is 6A during the
calibration, the dry running trip ampere is 4.2A)
④ Percent of load time of calibration ( i.e if the running ampere of pump motor is 6A during the
calibration, The pump stalled trip ampere is 12A)
