The working principle of PTC heater is based on the resistance temperature characteristics of PTC material. When the current passes through the PTC material, heat is generated inside the material, and the temperature rises accordingly. Due to the increase in resistance of PTC materials with temperature, the flow of current in the material is subjected to greater resistance, resulting in a decrease in heat generation, thus achieving automatic temperature control.

Linkwell LK series circuit breaker inspection protection window cover is an important protective accessory for electrical components such as small circuit breakers, molded case circuit breakers, isolation switches, switch sockets, instruments, reset buttons, emergency stop and rotary switches. It provides water, dust, and corrosion protection for sockets and circuit breaker switches inside the box. The transparent protective window cover can not only be waterproof, but also show the electrical switches inside

A waterproof distribution box is an effective device for outdoor circuit power distribution and safety protection. It has characteristics such as waterproof, dustproof

Today, Linkwell editor will tell you four key points to pay attention to when choosing cabinet fans:

Fan heater can prevent the formation of water droplets, and the integrated axial flow fan provides strong air circulation, stabilizing the temperature inside the switch box. LINKWELL fan heater uses PTC heating elements and flame retardant reinforced engineering plastics.

Terminal blocks, as a commonly used component in electrical connections, play a very important role. Choosing and using wiring terminals correctly can not only ensure the safe operation of the circuit, but also improve operational efficiency and maintenance convenience.

The cabinet cooling fan is a commonly used cooling device in the computer room, which can effectively reduce the temperature inside the cabinet and ensure the normal operation of the equipment. However, many people still don't quite understand when choosing a cabinet cooling fan. Below, Linkwell editor will explain to you the precautions for selecting cabinet cooling fans

The role of fans and filters is to protect the heat generated by the equipment and human health, and effectively reduce the pollution in the air.
