Double-conversion UPS Protect PLUS M500

parallelthree-phasemodular

Overview
Protect PLUS M500 is a modular 3-phase UPS system combining a compact footprint, high AC/AC efficiency and a flexible scalable architecture. It supports hot-swappable 25 kVA power modules, enabling deployments from 25 kVA up to 600 kVA (up to 3 frames in parallel). The unit provides input PF > 0.99 and input THDi < 3% (even at low load) with AC/AC efficiency > 95% in double conversion and > 98% in ECO mode. A flat efficiency curve from 25% load ensures energy savings across typical load ranges.
