This is an APC Smart Line Interactive UPS rated 1500VA/1.5kVA (1200W), configurable as either a tower or a 2U rackmount unit, built to protect servers, networking gear or small comms rooms from power outages, sags and surges — a very common load-shedding mitigation product in the South African market. It includes a network management card for remote monitoring, a VRLA (sealed lead-acid) battery, and support for up to 5 external battery packs to extend runtime beyond the internal battery alone. APC's PowerChute software is compatible for graceful, automated shutdown of physical servers, virtual machines and HCI clusters when battery runtime gets low, protecting against unclean shutdowns. Warranty covers 3 years on the unit (repair or replace) and 2 years on the battery specifically, reflecting the shorter working life of UPS batteries versus the electronics.
