APC Rack ATS AP4450A 100/120V 15A 1U | Rack PDU, Transfer Switch

Keep single-source failures from becoming service interruptions with APC’s NetShelter Rack Automatic Transfer Switch. The AP4450A is built for racks that depend on continuous power and need automatic source transfer without manual intervention. When one input path drops, the ATS shifts connected equipment to the alternate source, helping sustain operations across servers, network gear, storage, and other load-sensitive infrastructure. This model is sized for practical enterprise deployment: 1U rack height, 15A capacity, 100/120V input, and 10 NEMA 5-15R outlets. That combination makes it well suited for environments where space is tight but power continuity still matters. The 5-15 input plug and 50/60Hz compatibility support common North American rack power configurations, while the compact footprint helps preserve valuable rack units for active equipment. Compared with basic power strips, an ATS adds a layer of resilience that procurement teams can justify quickly. It is not about adding features for their own sake; it is about protecting uptime, reducing manual recovery, and giving infrastructure teams a cleaner path to redundant power design. For edge sites, branch rooms, and enterprise cabinets with dual-source power, the AP4450A helps keep critical loads online when conditions change.
