EATS7 series automatic transfer switch is a PC class infrequent change-over switch, with two-station design (commonly used for A and standby for B) suitable for AC systems with AC 50-60Hz and rated current 6A-63A. The main function is when the main power (common power supply A) fails, the ATS will automati- cally switch to the backup power (Backup power supply B) to continue working (switching speed <50 milliseconds), which can effectively solve the troubles caused by power outages. Standard IEC 60947-6-1.

1.The temperature range of the operating environment is -5°C ~ +40°C, and the average temperature within 24 hours shall be lower than +35°C. And the temperature range of the storage environment is -25°C ~ +55°C, which can reach +70°C in a short time (within 24 hours).
2.The altitude of the installation site should be lower than 2000m.
3.The relative humidity at the installation site shall not exceed 50% when the ambient air temperature is +40°C. Higher relative humidity is possible at lower temperatures. For example: when the average minimum temperature of the wettest month is +20°C, the monthly average maximum relative humidity of that month can reach 90%. Appropriate measures should be taken to prevent condensation due to temperature changes.
4.ATS can be installed vertically or horizontally in the cabinet.
5.Protection grade: IP30
6.Polution grade: III
