Automatic & Manual Dual Mode: Switch seamlessly between city power (Grid, marked "") and backup generator (marked "") with our intelligent ATS transfer switch. Features both automatic and manual operation modes with clear indicator lights for real-time status monitoring. When utility power fails, the automatic transfer switch instantly transfers load to the backup source; when grid power restores, it automatically switches backno manual intervention required
Reliable Performance: Built-in over-voltage and under-voltage protection safeguards your connected equipment from unstable power supply. Unlike basic transfer switches, this ATS monitors voltage levels continuously and prevents damage from power surges or brownouts. Note: This unit provides voltage protection but does NOT include overload or short-circuit protectionplease ensure proper circuit breakers are installed upstream
