The APC Symmetra LX is a modular, scalable uninterruptible power supply (UPS) system designed for data centres and server rooms, built around N+1 redundant, hot-swappable power modules rather than a single fixed-capacity inverter. This listing is configured at 16kVA and is itself scalable up to 16kVA (its full modular range for this frame), meaning power modules can be added over time as load grows rather than needing to replace the whole unit. Symmetra LX systems are rack- or frame-mounted and typically paired with external battery packs sized to the required runtime. Used to protect critical IT infrastructure -- server racks, network gear, storage arrays -- from utility power outages and fluctuations, a particularly relevant feature in South Africa given load-shedding.
