Intelligent constant pressure controller for 2 pumps

Specifications

Intelligent constant pressure controller for 2 pumps

Power range:

200V Class: 0.5HP-10HP

400V Class: 0.5HP-10HP

Features:

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

(2) the 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.

Application:high-low residential community,hotel,hospital.....
