Lanberg Closed-Loop Thermostat 10A For Rack Cabinets With 19" Ear And Terminal Block Black

Equipment installed in Rack cabinets, such as servers, systems of emergency power supply, surveillance, CCTV, alarm etc. all require maintaining the temperature at an appropriate, steady level. There is a wide variety of fans, coolers that can help in solving this problem.

But what if the administrator would like to avoid their unnecessary, redundant work, operating costs, thereby extending their working life? Lanberg offers a simple and flexible solution that will easily accomplish this very goal: closed-loop thermostat AK-1505-B.

It enables temperature regulation inside of server rack cabinets by controlling the power supply to cooling equipment and/or products providing more efficient air flow. The device is equipped with a current contact, which is shorted (closed), and thus switches on the connected cooling only when the temperature, set previously by the user, is exceeded.

All this is possible due to the thermo-bimetallic sensor, which mechanically deforms under the influence of ambient temperature. In combination with the temperature sunken knob, it allows the operation of thermostat to be adjusted accordingly to the user's preferences.

AK-1505-B uses normally open contact to ensure that the device reacts as quickly as possible to changes in the ambient temperature.

The temperature sensor (thermobimetal) is characterized by various coefficients of thermal expansion, using the phenomenon of so-called temperature deformation. As an active element, those sensors have a "strip" installed within the thermostat consisting of two welded "strips" of metal, each with different coefficient of thermal expansion.

The bimetallic “strip” is heated under the influence of the ambient temperature. Heated above a certain temperature, the strip is deformed, creating a contact with the contact point, which closes the electrical circuit and allows the current to flow.

When the temperature of the device or the environment drops to a certain temperature, the bimetallic strip returns to its original state and the electric circuit opens again.
