Intelligent Single Phase Sewage Pump Controller – Auto And Manual,0.37-2.2KW
Model: L922-S
Products Brief :
Model L922/S is specially designed for sewage pumping system, by adopting level transmitter with 0.5-4.5V analog signal, pump user can easily set the different liquid depth for sewage pump operation and observe the dynamic liquid depth in the sump or sewage tank.
Typical usage scenarios include:
– Houses - Flats
– Holidays houses - Farms
– Industrial plants - Construction site

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)
