SQ8T-63 Automatic Transfer Switch

SQ8T-63 Automatic Transfer Switch

• With two-station design (commonly used for A and standby for B), suitable for AC systems with AC 50-6ohz and rated current 6A-63A.

• Switch is when the main power (common power supply A) fails, the ATS will automatically switch to the backup power (Backup powersupply B) to continue working (switching speed <50 milliseconds).

• The temperature range of the operating environment is -5°C~+40°C,and theaverage temperature within 24 hours shalbe lower than +35°C.
