Vertiv APS 15 kVA Scalable to 20 kVA N+1 | Rack Mount UPS

Protect critical infrastructure with a modular UPS architecture designed for uptime, serviceability, and growth. The Vertiv Liebert APS 15 kVA Scalable to 20 kVA N+1 (AS4C0NCWGNNXLKB) uses online double-conversion power conditioning to isolate sensitive equipment from utility disturbances while maintaining stable output for mission-critical loads. Built for room-level deployments, this rack/tower system supports 230 V AC input with a 120 V AC to 280 V AC input range and 70 Hz input frequency tolerance. Its scalable design lets teams expand capacity to 20 kVA N+1 without replacing the platform, which helps preserve rack space, reduce refresh cycles, and align power investment with actual demand. Runtime matters when every minute counts. This model is specified for up to 15 minutes at full load and 39 minutes at half load, giving operators time to ride through short outages or complete orderly shutdowns. VRLA battery chemistry and an EPO port support established data center operating practices, while the 2-year limited warranty adds a defined support window for procurement planning.
