The APC Symmetra LX is a modular, N+1-redundant uninterruptible power supply platform for data centres and server rooms, built from hot-swappable power modules rather than a single fixed inverter. This listing is a 16kVA unit -- likely the same underlying hardware family as the 'scalable to 16kVA' Symmetra LX elsewhere in this catalog, described here simply as the UPS unit itself. It's designed to keep critical IT equipment -- servers, network switches, storage arrays -- running through utility power interruptions, a significant consideration in South Africa given regular load-shedding, and is generally deployed with external battery packs whose count determines runtime at a given load.
