Electronic pressure switch Switchmatic 2T - 400 V from Coelbo

Switchmatic 2 T is an electronic controller for three-phase pumps up to 4 kW. The controller switches the pump on and off depending on the pressure in the system. The device is equipped with a control panel with a display, which is intuitive for the user and allows him to make his settings. It also gives a real-time current reading. The controller can function as a differential switch and pressure changeover switch. The Switchmatic 2T includes a protection system against overloads, dry running and rapid cycling. The controller can be synchronized with another Switchmatic device. The electronic pressure switch reduces energy consumption and significantly extends the life of pumps and equipment in the system. It ensures constant pressure in the system, which improves the comfort of users.

For more information, see the data sheet and instructions.

Characteristics of the electronic controller Switchmatic 2T - 400 V:

  • On/off pressure control.
  • Built-in digital pressure gauge with indication in bar and psi.
  • Internal pressure transducer.
  • Real-time current consumption reading
  • ART (Automatic Reset Test) function; if the unit stops the pump to protect against dry running, it will try at a scheduled frequency to restart the pump to restore the water supply.
  • Rapid Cycle Change; if the hydropneumatic reservoir loses too much air and frequent start/stop cycles occur, there will be an alarm to delay pump start.
  • 3 operating modes: differential, return and synchronized.
  • Control panel with 3-digit display, LED indicators and buttons.
  • Settings: standby mode, minimum interval between fast cycles, start/stop delay.
