water pump controller:1HP~10HP(0.75KW~7.5KW),Single 220V/Three phase 380V,intelligent constant pressure water supply

water pump controller:

200 Class:0.5HP-10HP ; 400 Class:0.5HP-10HP

1small in size, can carry-on installed in the pump.

2the controller directly on the need to set the value of the constant pressure, constant pressure fully automatic operation.

3 the signal can choose a variety of pressure: pressure sensors, Far pressure gauge, pressure gauge electrical nodes.

4 multi-pump control linkage with the turn of automatic pump function between the two pump only a communication line to connect, share the pressure signal.

5 with a soft start and soft stop function. Avoid water hammer effect and impact on power grids. Double-pump can be set to control the rotation to rest, to extend the life of pumps and electrical accessories.

6 unattended, when the call after power, water pumps start automatically, constant pressure control (this feature is optional).

7 automatic fault detection, such as the water pressure is too high, too low, too low water level alarm, communications failures, and so on.

8 a full range of motor protection features such as: electrical overload, short circuit, open circuit, overheat and over-voltage and low voltage protection, and so on.

9 energy efficient, than the average of 30% of the secondary power supply -60%.

10 double-pump can be linked, no auxiliary pump, auxiliary pump in a dormant state in peacetime, when the auxiliary pump water during the height of the peak automatically add water, high capacity utilization.
