NLS sources double-conversion UPS units classified VFI under IEC 62040-3 for Saudi hospital essential branches and data centre loads.
A modular UPS builds capacity from hot-swappable power modules, typically 25-100kW blocks, inside one frame, so N+1 redundancy comes from adding one extra module rather than a second full UPS, and a failed module gets replaced live without dropping the load.
