Coelbo Switchmatic 2T 3 phase pressure switch
Digital differential pressure switch**NEW**
Electronic pressure switch. Patented Model.
The SWITCHMATIC 2 T is a three phase electronic pressure switch with an integrated digital pressure gauge.
It can manage the start and stop of 3-phase electric pumps.
General electric supply is 400Vac.
Cut-in and cut-out pressure can be set easily and accurately through user friendly control panel.
Wiring is carried out identically to a conventional pressure switch.
SWITCHMATIC 2T includes also instantaneous current readout and voltage.
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 over current, voltage out of range protection, the dry-running protection of the pump and fast cycling protection.
