APC by Schneider Electric Automatic Transfer Switch (AP7722A)

Designed for mission‑critical deployments in data centers, network rooms, and telecom closets, the APC AP7722A Rack Automatic Transfer Switch delivers dependable, redundant power to single‑corded equipment. This Rack ATS is engineered to keep your essential devices powered even in the face of imperfect power conditions by providing two input power cords that feed the connected load. When the primary source becomes unavailable due to utility interruptions, brownouts, or generator transitions, the Rack ATS seamlessly sources power from the alternate source with minimal interruption. The result is enhanced uptime, fewer maintenance windows, and greater peace of mind for servers, storage arrays, switches, routers, and other vital IT hardware. The compact, rack‑mountable form factor fits neatly into standard 19‑inch racks, preserving valuable floor space while delivering robust electrical protection right where you need it most. Beyond simple redundancy, the AP7722A integrates with APC’s broader power management ecosystem, enabling centralized monitoring, alerting, and coordination with UPS systems for a holistic, scalable approach to power protection. Its emphasis on safety, performance, and reliability makes it a practical upgrade for both existing rack infrastructure and new builds, delivering consistent power delivery and a robust line of defense against unexpected outages.

• Dual input cords provide redundant power paths to the connected load, ensuring an alternate source is ready to take over without manual intervention and reducing single points of failure in critical environments.
• Automatic transfer with rapid switching maintains continuity for sensitive equipment; when the primary source becomes unavailable, the Rack ATS switches to the secondary source with minimal disruption to operations.
• Rack‑mount design fits standard 19‑inch racks, optimizing data-center real estate while maintaining proper clearance for cooling and maintenance, and enabling centralized power protection across multiple racks.
• Built‑in electrical protections—including surge suppression, overcurrent control, and fault isolation—help shield connected devices from common power disturbances and improve equipment longevity.
• Seamless integration with APC UPS systems and management tools enables coordinated, scalable protection across the IT environment, simplifying monitoring, reporting, and maintenance of redundant power paths.

How to Install AP7722A

• Plan the installation in a well‑ventilated area and prepare a standard 19‑inch rack rack‑mount space with adequate clearance for access and cooling around the AP7722A.
• Mount the Rack ATS securely in the selected rack rails using the appropriate hardware; verify the unit is level and firmly seated to prevent vibration and strain on cables.
• Connect the two input power cords to two independent power sources or outlets that meet the device’s electrical requirements; route cables neatly to prevent interference and ensure proper airflow.
• Connect the load to the Rack ATS output, ensuring that the total load does not exceed the device’s rated capacity and that cables are labeled for easy identification during maintenance.
• Power up the primary source first, followed by the secondary source, and confirm the unit recognizes both inputs; test the automatic transfer by simulating an outage on the primary source to verify seamless switching.
• Configure any available management settings or software integrations for monitoring and alerting; verify status indicators and logs verify healthy operation and readiness for real‑world transfer events.
• Perform a functional test under normal load conditions to validate that the transfer occurs without unexpected closures or warnings, and document the test results for future reference and audits.
