Tekswitch

Multifunction digital electronic pressure switch with over-current protection electropump and dry running

Tekswitch is an electronic pressure switch with integrated digital pressure manometer. It allows to manage the start, stop and protection of a singlephase pump of up to 2.2 kW (3 HP). The pressures are easily set by the user and the connections are similar to that of a traditional pressure switch for pressurization systems. It can operate as a differential or reverse pressure switch, it includes the reading of the ampers of the electric pump and protects it in case of overcurrent, it can be mounted individually or in groups of 2 pumps operating in cascade with alternation and contemporaneity management. It is equipped with a dry running protection system and lock for too many close starts.
