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

When uptime matters, fixed-capacity backup can become the weak point. The Vertiv Liebert APS 15 kVA Scalable to 20 kVA N+1 is designed for environments that need more headroom from day one and a clear path to growth. Starting at 15,000 VA, it scales to 20 kVA N+1 so infrastructure teams can match protection to expanding load without replacing the entire power platform. The UPS accepts a 120 V AC to 280 V AC input range, helping it ride through unstable utility conditions while delivering 230 V AC output to connected systems. For outage coverage, it provides 5 minutes at full load and 15 minutes at half load, enough time to bridge short interruptions or complete an orderly shutdown. Valve regulated lead acid batteries provide proven backup performance, and the integrated temperature sensor adds useful environmental visibility. Its rack/tower form factor supports deployment in data rooms, edge sites, and mixed infrastructure spaces where installation flexibility matters. An EPO port is included for emergency shutdown control. For teams evaluating power protection at a higher tier, this model offers the capacity, runtime, and scalability that justify the investment.
