Frequently Asked Questions
What is a rack automatic transfer switch and why do I need one?
A rack automatic transfer switch monitors two independent power sources and automatically switches connected equipment to the backup source if the primary power fails. This eliminates downtime for critical servers and network devices, making it essential for data centers, server rooms, and any environment where continuous uptime is required.
How fast does the APC NetShelter AP4450A transfer between power sources?
The AP4450A transfers power in approximately 10ms, which is fast enough to prevent most equipment from experiencing interruption. This rapid failover ensures connected devices remain operational during power transitions between the dual NEMA 5-15P input sources.
Can I manage multiple APC NetShelter rack ATS units remotely?
Yes, the AP4450A includes a field-replaceable network management card that supports Ethernet and USB connectivity. You can manage up to 32 rack ATS units from a single IP address, providing centralized monitoring and control across your entire power infrastructure.
What power capacity does the AP4450A provide for my equipment?
The AP4450A delivers 1440VA at 15A, 100-120V, making it suitable for powering multiple rack-mounted servers, switches, storage systems, and other IT equipment. The ten NEMA 5-15R outlets distribute this capacity across your connected devices with automatic load balancing.
