COELBO Electronic Pressure Switch With An Integrated Digital Pressure Gauge, 110/220V, 1P, 108 PSI, IP65, Model SWITCHMATIC 2

Download spec sheet Electronic pressure switch. Patented model. This unit SWITCHMATIC 2 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 user friendly control panel. Wiring is carried out identically to a conventional electromechanical switch. It can operate as a differential pressure switch or as an inverted pressure switch. SWITCHMATIC 2 also includes instantaneous current lecture and it can be mounted individually or in groups of 2 pumps synchronized and operating in cascade mode with alternated sequence of operation. This patented version controls and manages the overcurrent, the dry-run protection of the pump and fast cycling protection. OPERATING CHARACTERISTICS – Operation modes: differential, inverted and synchronized (only SWITCHMATIC 2). – Inner pressure transmitter. – Integrated pressure gauge with bar and psi instantaneous display. – User friendly control panel including manual start push-button, 3-digits display, led-lights and pushbuttons. – Dry-running protection by current (SWITCHMATIC 2) – ART function (Automatic Reset Test). If the device has been stopped 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. – Rapid-cycle alarm: when the hydropneumatic tank has lost the air and frequent start-stops are produced an alarm is activated and is delayed the start. – Overload alarm (only type SWITCHMATIC 2). – Sleep mode with low power consumption. – Advanced configuration menu: differentials, delay settings and other parameters.     .tech-specs-wrap{ max-width: 520px; font-family: Arial, Helvetica, sans-serif; } .tech-specs-title{ font-size: 18px; letter-spacing: .5px; text-transform: uppercase; color: #b5b5b5; font-weight: 700; margin: 0 0 10px 0; } table.tech-specs{ width: 100%; border-collapse: collapse; border: 1px solid #d9d9d9; table-layout: fixed; } table.tech-specs th, table.tech-specs td{ border: 1px solid #d9d9d9; padding: 10px 12px; font-size: 14px; line-height: 1.2; } table.tech-specs th{ font-weight: 700; text-align: center; background: #ffffff; } table.tech-specs th:first-child{ width: 62%; } table.tech-specs th:last-child{ width: 38%; background: #d8d2cc; } table.tech-specs td:first-child{ background: #ffffff; font-weight: 600; color: #333; } table.tech-specs td:last-child{ background: #d8d2cc; text-align: center; font-weight: 700; color: #333; }   TECHNICAL CHARACTERISTICS SWITCHMATIC 2 Power supply voltage ~1 × 110–230 VAC Frequency 50/60 Hz Max. current 16 A Maximum pump power 3 HP Starting pressure range (cut-in) 7 – 102 psi Stop pressure range (cut-out) 15 – 116 psi Maximum differential 109 psi Minimum differential 4 – 7 psi Factory setting (cut-in / cut-out) 44 / 58 psi Protection rating IP55 Max. water temperature 104 °F Max. ambient temperature 122 °F Net weight (without cables) 0.88 lbs Inlet thread 1/4″ NPT
