APC Rack Automatic Transfer Switch (ATS) 1U 20A 120V (AP4423A)

Deliver instant, fail-safe power redundancy to single-corded IT equipment with this high-speed, network-managed 120V transfer switch.

Data centers spend millions of dollars deploying dual UPS systems and redundant backup generators, but none of that infrastructure matters if your edge routers, firewalls, or legacy servers only have a single power supply. If the specific UPS feeding that single-corded device requires maintenance or fails, your critical hardware drops with it. The APC Rack Automatic Transfer Switch (AP4423A) completely eliminates this single-cord vulnerability. Occupying just 1U of valuable rack space, this advanced ATS accepts two discrete 120V power inputs (Primary and Secondary). If the primary power source experiences an anomaly or fails entirely, the AP4423A seamlessly and automatically transfers the load to the secondary power source in a fraction of a second—ensuring your most critical networking gear never drops a single data packet.

Key Features & Benefits:

  • Seamless High-Speed Transfer: Engineered for mission-critical reliability. The unit transfers power between the primary and secondary sources in under 10 milliseconds, ensuring continuous operation without rebooting or locking up sensitive IT equipment.

  • Embedded NMC3 Management: The "A" in the AP4423A SKU indicates the upgraded Network Management Card 3. Gain secure, Gigabit-speed remote control over your power routing with advanced cybersecurity protocols, including TLS 1.3, SNMPv3, and secure boot capabilities.

  • Color LCD Display: No more guessing in a dark server aisle. The vibrant front-panel LCD provides real-time local aggregate current draw, voltage monitoring, and immediate visual alarms, allowing for rapid on-site diagnostics.

  • Dual 20-Amp Inputs: Maximize your 120V infrastructure. Fed by two robust NEMA L5-20P twist-lock inputs, this switch provides enough capacity to fully populate its 8 rear outlets with high-draw networking switches and edge servers.

  • Proactive Load Monitoring: Prevent tripped breakers before they happen. The network interface sends automated threshold alarms directly to your smartphone or EcoStruxure dashboard if the aggregate current draw approaches the 20-Amp maximum.
