A Modular UPS is built from multiple hot-swappable power modules within a common frame, allowing capacity and redundancy to be scaled by adding or removing modules. This design supports pay-as-you-grow expansion, fast module-level maintenance and flexible N+1 redundancy, improving availability and matching installed capacity to actual load.
