Overview of temperature and humidity control can be used for low voltage switch cabinet, box-type substation, terminal boxes and other electrical control devices with high accuracy and strong anti-jamming capability, used in conjunction with the heating and dehumidification element to achieve the effect of temperature and humidity control . Function 1, real-time monitoring of the temperature control device logic ambient temperature, when the measured ambient temperature is below 5 ℃, the device automatically start the heater to heat, once the ambient temperature rose to 15 ℃, the device automatically stops heating output. 2, condensation logic control device in real-time monitoring of environmental humidity, when the measured humidity Kai condensation control points higher than 93% RH, the unit will automatically start the heater dehumidifier environment, prevent condensation generated once the condition is no longer produce condensation When satisfied, the device automatically stops the heating output. 3, when the heater burnout alarm malfunction can not meet the heating requirements, fault indicator light alarm indication. At the same time, the alarm output terminal is normally closed. Specifications 1, Power supply: AC220V ± 10% 2, the working environment: Temperature -20 ℃ ~ 70 ℃ Humidity ≤95% RH 3, the temperature zone control: 5 ℃ ~ 15 ℃ 4, the temperature control precision: ± 2 ℃ 5 Humidity control range: 10% RH ~ 95% RH, Kai condensation control: 93% RH 6, the output contacts: resistive AC220V, 3A active; alarm contact: AC220V, 2A 7, power consumption: ≤2W 8, reliable Safety: Complies with the requirements of IEC834-1 9, size: 48mm × 48mm × 90mm 10, hole size: 45mm × 45mm 11, Installation: panel type, base type or use a rail,, power press wiring diagram , power indicator light, when the temperature is too low to meet the heating conditions, the work lights that heater. When the temperature rose to a certain value, the heater is automatically stopped. 2. To test the heating operation of the wet feeling after condensation, at temperatures greater than 20 degrees environment, the humidity sensor can be placed in the refrigerator for about 5 minutes after the removal, to die like condensation conditions or humidity sensor Kazakh gas method to observe the work under condensation conditions.
