IP54 Digital Pump Controller With Available From 0.75-250kw ,Control Two Pumps By Inner Pcb Drive ,Auto &Manual Two Modes Switch


  • General Introduction:

Model SC2 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


Three probes or Float switch within the tank will inform the controller when the tank has been pumped dry, when a tank is in danger of overflowing, or when a normal pump cycle needs to be initiated. The probes may be either submersible float switches or conductive probes set to different levels within the tank.

A number of alarm conditions will be declared and recorded where normal operating parameters have been exceeded.

The unit features an advanced microprocessor controller bonded to the pcb board within the enclosure. Heavy contactors and current overload devices support three phase 380VAC pumps with Start/Run motor windings and an average load current of up to 500 Amps. An integrated dry contact point ensures protection against water leakage faults(optional)

The cabinet is an extremely tough metal composition, with stainless steel hinge and latches and foam door seals. The cabinet is intended to be wall mounted with brackets provided or vertical position,and cable access may be effected from under of the unit

customer needs to define
in advance
Pumps run in alternation
and also parallel if required
Yes ,pumps alternation on
every start cycle
in most cases it is done
as per timing
If one pump failsSecond pump starts&
give an alarm
Second pump doesn't start,
alarm,system needs to be

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)
