Power Supply Detection: The switch continuously monitors the voltage of the main power supply (common power source).
Fault Diagnosis: When a fault is detected in the main power supply (e.g., power outage, undervoltage, phase loss), the switch automatically disconnects from the main power supply.
Switching to Backup Power: Subsequently, it quickly connects to a backup power source (e.g., a generator or another power grid), switching the power supply to the load.
Recovery Operation: When the main power supply returns to normal, the switch will switch the load back to the main power supply and disconnect from the backup power supply.
Equipped with automatic switching function, requiring no manual intervention and ensuring continuous power supply.
Features reliable mechanical and electrical interlocking to prevent simultaneous closing, avoiding short-circuit accidents.
Enables automatic switching for critical electrical faults including overvoltage, undervoltage, and phase loss.
Supports "four remote" functions: remote control, remote operation, telemetry, and remote signaling.
Rapid switching speed (typically over 100ms for mechanical structures) minimizing critical equipment downtime.
Features clear position indicators and padlock functions for achieving reliable power isolation.
