• WORKING PRINCIPLE: The 4P dual power automatic transfer switch supports automatic and manual operation, and can switch between two power sources automatically or manually. It can monitor the status of the main and backup power sources in real time. When power supply A fails, the ats transfer switch will switch to power supply B within 2 seconds to ensure continuous, reliable, and safe power supply. Once source A is restored, it will automatically switch back. Both power inputs support power, generator, or photovoltaic connections
• AUTOMATIC TRANSFER SWITCH MODE: Simply set the top switch to "Auto", the red LED indicator light on the upper left side is on. When main power (N) is normal, the red LED indicator light on the lower left side is on. If main power fails, the system automatically switches to backup power (R) within 2 seconds, the red LED indicator light at the bottom right is on. When main power is restored, generator transfer switch automatically switches back, ensuring your equipment stays on without interruption
• MANUAL TRANSFER SWITCH MODE: Set the top switch to "Manual" mode. You can then use the handle to manually select either Main (N) or Backup (R) power. The corresponding red LED will light up to indicate a stable power source. If manual transfer switch the handle is in the middle position, both power sources will be disconnected. This mode is perfect for load testing, system checks, or any situation that requires direct control
• MULTIPLE PROTECTION: Built in safety protection mechanisms of the automatic transfer switch includes over-voltage,under-voltage and over-current protection,ensuring the safety of your electrical devices. Made of high-quality PA6, it has high strength, high temperature resistance
• WIDE APPLICATION: This 4p ats automatic transfer switch ensures a stable power supply, it is used in situations where power outages cannot be sustained,which is very suitable for high-demand equipment; used in hospitals, low-temperature cold storage, data centers and emergency systems, particularly in office buildings and public spaces with fire safety requirements, it can automatically and quickly switch to the backup power supply during the power outage of the main power supply to ensure safe and reliable power supply. Suitable for indoor and outdoor generators
