This is an APC Smart Line Interactive UPS rated 3000VA/3kVA (2700W), configured as a standalone tower unit with no rack-mount kit included. It's a step up in capacity from the 1500VA sibling elsewhere in this catalog, suited to protecting a larger single server, a small cluster of networking equipment, or a modest server room from outages and power quality issues — a common load-shedding-protection purchase in South Africa. It uses a VRLA (sealed lead-acid) battery and, like the smaller model, is compatible with APC's PowerChute software for automated graceful shutdown of connected systems. Warranty covers 3 years on the unit and 2 years specifically on the battery, which typically wears out faster than the electronics.
