Dns-d306m is a high-pressure pressure switch for refrigeration, air conditioning and various industrial equipment. It controls the high and low pressure of the chiller at the same time. It has the capability to manually reset and is required to press the rebrand button after the pressure changes。


Here's the thing:
Dns-d306m has four main lines, one, two, three and four。
The 1st and 2nd ends are the points on the high side and the 3rd and 4th ends on the low side。
The electrical resistance between the 1st and 2nd ends changes with pressure on the high pressure side, and when the pressure exceeds the given value, the point is cut off and the circuit is cut off. When the pressure is lowered below the set value, the interface is closed and the circuit is reconnected。
Electrical resistance between 3 and 4 ends varies with pressure on the low pressure side, when the pressure is below the set value, the point of contact is disconnected and the circuit is cut off. When the pressure rises to a given value, the interface closes and reconnects。
The 1st, 2nd and 3rd and 4th ends are independent and can be linked to different circuits。
When connected, care should be taken to comply with electrical safety norms and to use appropriate guidance and protection devices
