EHT electronic humidity controller

EHT electronic humidity controller is an excellent humidity regulator used to protect general equipment cabinets. EHT has three major characteristics - compact design, easy installation, and simple operation; Its electronic components can accurately detect every change in relative humidity and turn on other devices (such as heaters) when the set humidity is reached to help control the humidity inside the cabinet. It can also be used to turn on other signal devices or dehumidifiers.

Users can check the switch status through LED lights (the LED should be constantly on when the circuit is closed); The built-in high-capacity relay (up to 8A) can directly control multiple devices and is compatible with the vast majority of DBK heaters (please refer to the related products below for details); In addition, EHT also provides a second passive dry contact. EHT is embedded with high specification components, making it far superior to traditional machine type hygrometers in terms of sensitivity and reliability, and can better control hysteresis phenomena; And it can effectively prevent frost, once the temperature drops below 4 ° C, the connected devices will be turned on. The knob style design and 5% adjustment unit can greatly improve the accuracy of settings; And the input voltage range is also relatively loose, giving the voltage system of the power supply a certain degree of flexibility.
