Description
The Vertiv VA4N22A1 is a high-reliability Rack Transfer Switch (RTS) that delivers redundant power to single-corded devices, ideal for mission-critical IT environments. Designed for seamless operation, it automatically transfers load power within 4–8 milliseconds upon primary source failure—no phase synchronization required.
This 1U horizontal rPDU supports input power monitoring, optional environmental sensors, and robust remote management via Ethernet daisy-chaining. With 20 NEMA 5-20R outlets and dual NEMA L5-20P input cords, it ensures uninterrupted performance, system uptime, and infrastructure insight through real-time monitoring.
