APC SMART-UPS RT SURT20KRMXLT 20 kVA 208V | Online UPS, Rack Mount

Protect mission-critical infrastructure with the APC Smart-UPS RT SURT20KRMXLT. Built around double-conversion online power protection, it conditions utility power continuously so connected systems see a stable output even when the source is not. With 20 kVA and 16 kW capacity, this model is designed for demanding rack environments that need serious power headroom. Runtime is measured for real operational response: 4.9 minutes at full load and 15.3 minutes at half load. That gives teams time to ride through short outages, complete graceful shutdowns, or transition to generator power without rushing. The rack-mount form factor supports dense infrastructure layouts, while hot-swappable, maintenance-free, spill-proof lead acid batteries help reduce service friction. Connectivity matters at this tier. DB-9 RS-232, RJ-45 10/100 Base-T, and SmartSlot support give administrators the interfaces needed for monitoring and integration into managed power environments. For organizations protecting virtualization clusters, storage, or core network gear, this UPS is built for the cost of downtime, not the cost of entry.
