ELS Modular Online UPS (50 - 600kVA)

ELSIPOWER 50–600 kVA modular online UPS uses 3-level IGBT and DSP control with 4U 50 kVA power modules (60 kVA in the 600 kVA cabinet). With 200, 300, 400 and 600 kVA cabinets, 500 kVA in under 1.5 m² and expansion to 1800 kVA with three parallel systems, it protects large data centers.

Compact Design: 500 kVA in one cabinet with a footprint below 1.5 m².
High Power Density: 50 kVA power modules in 4U height for easy expansion.
High Efficiency: Up to 96% efficiency in online double-conversion mode.
High Scalability: Expandable to 1800 kVA with three parallel systems.
