A Modular UPS is an advanced uninterruptible power supply system built using independent, hot-swappable power modules instead of a single fixed-capacity unit. This modular design allows the UPS capacity and redundancy to be scaled up or down easily by adding or removing modules as power requirements change.
Modular UPS systems typically use online (double-conversion) technology, providing continuous, clean, and reliable power with zero transfer time. If one module fails, others continue operating, ensuring high availability and fault tolerance without system shutdown.
