The temperature and humidity controller products are mainly used for regulating and controlling the internal temperature and humidity of medium and high voltage switchgear, terminal boxes, ring main units, box transformers and other equipment. canEffectively prevent equipment failures caused by low and high temperatures, as well as creepage and flashover accidents caused by moisture or condensation.The sensor detects the temperature and humidity information inside the box and transmits it to the controller for analysis and processing. When the temperature and humidity inside the box reach or exceed the predetermined levelWhen the set value is reached, the relay contacts in the controller close, and the heater (or fan) is powered on to start working, heating or blowing air inside the box;After a period of time, if the temperature or humidity inside the box deviates from the set value, the relay contacts in the controller will disconnect, and heating or blowing will stop. Not except for basic functionsThe same model also comes with auxiliary functions such as wire breakage alarm output, transmission output, communication, and forced heating and blowing.
