SWITCHMATIC 3 is an electronic pressure switch with integrated digital pressure gauge with dry contact output for control panels. It can manage the start and stop of single-phase electric pumps up to 3 HP (2,2 Kw). Cut-in and cut-out pressure implementation can be set easily and accurately. Wiring is carried out identically to a conventional electromechanical switch. Its dry contact output it´s ideal for transmitting an open/close signal to an external control panel. This unit also includes a volt free contact for monitoring the alarms displayed in the screen.
- Dry contact output for control panels.
- Volt-free contact for monitoring the alarms displayed in screen originated by irregularities or problems of the system (Only type Switchmatic 3A).
- ART function (Automatic Reset Test). If the device has been stoped due the action of the safety system against dry operation, the ART tries to connect the pump, with a programmed periodicity because the water supply could have been restored.
