Vertiv Liebert APS 20 kVA N+1 Rack/Tower UPS | Modular, Enterprise

Maintain continuity for critical infrastructure with the Vertiv Liebert APS 20 kVA Scalable to 20 kVA N+1 modular UPS. Designed for mission-critical rooms, this rack/tower system uses online double-conversion architecture to isolate connected loads from unstable utility power while delivering clean output for sensitive equipment. With 20 kVA capacity and up to 10 minutes of runtime at full load, it gives IT teams time to ride through short outages, complete controlled shutdowns, or bring standby generation online. At half load, runtime extends to 26 minutes, adding flexibility for lighter operating states. The scalable N+1 design supports higher availability targets by adding redundancy at the system level, which is a meaningful advantage over fixed-capacity UPS units. The unit accepts 230 V AC input with a 120 V AC to 280 V AC range and includes an EPO port for emergency power-off integration. Valve regulated lead acid batteries provide proven backup performance in enterprise environments. For teams standardizing on infrastructure that can grow with demand, this model offers the capacity, resilience, and service profile expected in higher-value deployments.
