Pump driver with speed variator

  • ECOVAR pump driver manages and protects pressure equipments up to 3 pumps, by means of a reliable electronic control system. Besides, constant pressure is achieved regardless of the flow request, changing the motor speed by means of an INVERTER system in the control of power.
  • Main pump regulated by INVERTER and auxiliary pump/s in cascade through direct starting-up (alternation only between auxiliary pumps).
  • Control panel with LCD screen with warning leds, START/STOP and AUTOMATIC push buttons
  • Configuration system for easy and intuitive programming
  • Pressure reading through internal pressure transducer
  • Intensity current sensor with instantaneous reading
  • Protections agains lack of water by consumed current, overcurrent, fast operating cycles and abnormal supply voltage
  • ART function (Automatic Reset Test), which restarts the pump with a programmed periodicity until the water supply has been restored.
  • Register of alarms and operational controls (working hours, start counter, connections to the electrical network counter)
  • Automatic restart system after an interruption of power supply keeping the confi guration parametres
  • It’s possible to connect a level switch as protection. This system is independent from the safety system against dry running operation
