What is temperature and humidity controller?

The temperature and humidity controller controls the internal temperature and humidity of the power distribution system equipment. Reduce accidents.

How does a temperature and humidity controller work?

When the temperature and humidity in the distribution box reach the threshold, control the heater (or fan) to work, and perform auxiliary functions such as heating or blowing.

Application of temperature and humidity controller?

Medium and high voltage switchgear, terminal box, ring network cabinet, box transformer and other equipment.

How does a controller measure temperature and humidity?

Through the temperature and humidity sensor.

Acrel Temperature And Humidity Controller, Digital Temperature And Humidity Controller



Acrel Temperature and humidity controller products are mainly used for the internal temperature and humidity control of medium and high voltage switch cabinets, terminal boxes, ring network cabinets, box transformers and other equipment. It can effectively prevent equipment failures caused by low temperature and high temperature, as well as creepage and flashover accidents caused by moisture or condensation.

What is Temperature Humidity Controller Working Principle?

The temperature and humidity controller is mainly composed of three parts: sensor, controller, heater (or fan, etc.), and its working principle is shown in the following figure:

The sensor detects the temperature and humidity information in the box, and transmits it to the controller for analysis and processing: when the temperature and humidity in the box reach or exceed the preset value, the relay contact in the controller is closed, and the heater (or fan) ) to start working when the power is turned on, heating or blowing the inside of the box, etc.; after a period of time, the temperature or humidity in the box is far from the set value, the relay contacts in the controller are disconnected, and the heating or blowing stops. In addition to the basic functions, different models also have auxiliary functions such as disconnection alarm output, transmission output, communication, and forced heating and blasting.
