1. Key models

CG208E-RS, CG217EF-TH, CG227E-PQ, CG237E and CG239E etc.

2. Product overview

The CG200 series digitally displays the temperature, humidity value and temperature and humidity control range inside the power equipment cabinet, and monitors the high temperature, low temperature and over-humidity status inside the cabinet in real time. The heater or exhaust fan switch is automatically controlled according to the on-site conditions. Multiple protection measures effectively prevent component failure caused by excessively high or low temperature in the cabinet or accidents such as creepage and flashover caused by excessive humidity with the features of small start-up control point error, timely and accurate fan action, high stability and high reliability.
