NK-P rotary knob condensation controller high-voltage distribution cabinet dehumidifier heating and cooling

summary：

             A temperature and humidity controller is mainly used for power equipment such as outdoor terminal boxes, high and low voltage control cabinets, box-type substations, circuit breaker mechanism boxes, and instrument boxes, as well as other places that require automatic dehumidification, dew prevention, and temperature control. It can effectively prevent various accidents caused by excessively high or low humidity and temperature. The intelligent temperature and humidity controller uses a digital temperature and humidity sensor to display temperature and humidity values on a digital tube. It also has fan and heater contact points, and features heater disconnection alarm and sensor fault indication functions. The product can also be equipped with an RS485 communication interface or alarm switch output to transmit environmental temperature, humidity values, and working state parameters to the upper computer for remote monitoring, suitable for unattended substations. Users can set temperature and humidity upper and lower limits, cyclic display mode, communication parameters, etc., through buttons. The product has strong anti-interference capability, high feasibility, and complies with GB/T15309-1994.

It has continuous humidity control: humidity is adjustable. In standby mode, the sensor detects changes in the surrounding humidity and sends relevant parameters to the internal circuit of the controller for processing. When the humidity is too high, it drives the external load to heat or ventilate, forcing the medium to be modified to meet standard working conditions. The controller disconnects the external load when the humidity increases to the sum of the set value and the hysteresis, or decreases to the difference between the set value and the hysteresis, returning to the detection state, and this process repeats automatically.
