This unit SWITCHMATIC is an electronic pressure switch with an integrated digital pressure gauge. 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 through a user friendly control panel. Wiring is carried out identically to a conventional electromechanical switch. It can operate as a differential pressure switch, as an inverted pressure switch, or just with max. or minimum pressures. SWITCHMATIC 2 includes also instantaneous current lecture, this patented version controls and manages the overcurrent, the dry-running protection of the pump and fast cycling protection.

Operating characteristics: – Inner pressure transmitter – User friendly control panel with 3-digits display, led-lights and push-buttons. – Integrated pressure gauge with bar and psi instantaneous display. – Four operation modes: Differential. Inversed differential. Maximum pressure. Minimum pressure. – Manual start. – Dry-running protection (only type Switchmatic 2). – Rapid-cycle alarm: when the hydropneumatic tank has lost the air and frequent start-stops are produced an alarm is activated (only type Switchmatic 2). – Overcurrent protection (only type Switchmatic 2). – ART function (Automatic Reset Test). If the device has been stopped due to the action of the safety system against dry operation, the ART tries to connect the pump, with a programmed periodicity untill the water supply is restored (only type Switchmatic 2) – Sleep mode with low power consumption. – RoHS and WEEE compliant. – EMC certified and Electrical Safety certifed.
