100A 110V Automatic Transfer Switch2P Mini Dual Power Transfer Switch50Hz 60Hz 35mm Din Rail Mounting for Home Generator Factories Laboratories Farms Powering Supply

- FUNCTIONS AND FEATURES:This 110v transfer switch ensures seamless power supply by automatically or manually switching between two sources. It allows you to test the status of both common (A) and backup (B) power supplies. The Automatic transfer switch is rated for 100A, 110VAC,reliable transmission, and easy 35mm DIN rail installation.this Automatic transfer switch is widely used in homes, factories, laboratories, farms, data centers, and emergency systems - AUTOMATIC MODE OPERATION:When set to Auto, the Automatic transfer switch continuously monitors the main power (A). If an abnormality is detected, it switches to the backup source (B) in under 50ms (<0.05s). Once the main power returns to normal, it automatically switches back, ensuring continuous and reliable power supply without interruption - MANUAL MODE OPERATION:In Manual mode, you have full control. Simply turn the selector to "Manual" and use the handle to choose Source A or Source B. This mode is ideal for testing circuits, performing maintenance, or when manual intervention is required, offering both flexibility and safetyMANUAL MODE OPERATION:In Manual mode, you have full control. Simply turn the selector to "Manual" and use the handle to choose Source A or Source B. This mode is ideal for testing circuits, performing maintenance, or when manual intervention is required, offering both flexibility and safety - 110V AC SYSTEM REQUIREMENT:This transfer switch 110v is specifically designed for 110V AC 50/60Hz systems. It includes built-in voltage monitoring that responds to complete power failure or significant under-voltage/over-voltage events on the main line. Please ensure your working voltage matches this specification before installation. Select the correct switch based on your actual system voltage - TROUBLESHOOTING (If Switch "Does Not Work"):Most issues are caused by simple setup errors:Check Wiring: Incorrect connections are the cause. Verify Main (A), Backup (B), and Load (Output) terminals.Understand Logic: Switch only transfers when Source A fails?it won't act if both sources are normal.Verify Voltage: Complete power failure triggers switching; small fluctuations may not activate it.Test Manual Mode: If manual works but auto doesn't, issue may be with the sensing circuit
