Abstract (en)
[origin: EP3456973A1] Control apparatus of a pump supplied with three-phase current, comprising - a hydraulic section comprising in turn - an inlet for the water coming from a pump with which the apparatus is associated, - an outlet for the water to be connected with a water system, - a first device sensitive to the pressure of the water interposed between said inlet and said outlet for the water adapted to verify a given pressure value of the water in the apparatus, - a second device sensitive to the flow of the water, interposed between said inlet and said outlet for the water, adapted to verify a given flow value of the water in the apparatus, - an electrical section comprising in turn - electronic means for managing the apparatus, operatively connected with said first device and said second device to control operation or switch-off of the pump based on the pressure and/or flow parameters detected, - a three-phase electrical input equipped with first terminals, one for each phase, for wiring adapted to connect said first terminals to the external three-phase power supply network, - a three-phase electrical output equipped with second terminals, one for each phase, for wiring to corresponding terminals of the pump.
