FUNCTION

Temperature and  Humidity Controller for Switchgear is widely used in 0.1-35KV indoor  switchgear and primary loop control cabinet and provides real-time and  precise monitoring process about environment temperature and humidity to  prevent accidents caused by dampness and flashover to improve electric  network security.

SPECIFICATIONS

There  are four parameters needed to specify the temperature and humidity controller.
 1. Cut-out size of switchgear cabinet

2. Power supply type.

3. Humidity sensor wire length.

4. Driving load power.

RANGE

 Power supply type:  AC220V/DC220V/DC110V

 Standard humidity sensor wire length is 3m.
