5. Delovanje

The APC Rack ATS AP4452 is designed for automatic operation, providing seamless power redundancy to connected equipment.

5.1. Automatic Transfer Operation

The unit continuously monitors the primary power source (Source A). In the event of a power failure or degradation on Source A, the ATS will automatically and instantaneously transfer the connected equipment to the secondary power source (Source B) without interrupting power to the load. When Source A recovers, the ATS will automatically transfer the load back to Source A (if configured for preferred source operation).

5.2. Load Monitoring

The AP4452 provides advanced load monitoring capabilities. The front panel display typically shows real-time current draw and other operational parameters. For more detailed monitoring and historical data, connect the unit to a network management system (if equipped with a network management card).

5.3. Remote Switching Control (for Switched Models)

If your AP4452 model includes switched outlets, individual outlets can be remotely controlled. This functionality allows for power cycling of connected equipment, delayed power sequencing during startup, and granular outlet use management. Refer to the specific documentation for the network management card or integrated web interface for detailed instructions on configuring and utilizing these features.
