Product Detail

1. Overview

Auto transfer switchgear mainly consists of the auto transfer device which can be switched between the normal power supply and backup power supply to ensure reliability and continuity of power supply. It is widely applied in the important places which need uninterrupted power supply such as buildings, post, and telecommunication, mining enterprises and shipping

3. Operation conditions

1. Ambient temperature: the maximum temperature is +40? and the lowest temperature is -5?. The average temperature in 24 hours should be less than +35?.

2.The relative humidity of ambient air should be less than 50% when the highest temperature is +40?. The higher relative humidity is allowed at a lower temperature, for example, when the temperature is +20?, the relative humidity can be 90%. Dewing may happen accidentally due to the change of temperature.

3. Altitude should be less than 2000m.

4. Earthquake magnitude should be less than 8.

5. The place should be free from serious contamination, chemical corrosion, and strong vibration.
