Three-phase UPS
30–200 kVA
Modular and monolithic UPS for computer rooms and mid-size mission-critical infrastructure.
Overview
High efficiency, scalable availability
Three-phase Liebert systems combine high double-conversion efficiency with modular redundancy — availability that scales with your business.
Platforms like EXM2, APM and SX use IGBT double-conversion with unity or 0.9 output power factor, delivering more usable kW while reducing installation and running costs.
Transformer-free designs cut footprint and cooling; Li-ion-ready options and remote diagnostics extend life and simplify service.
- Up to 97% efficiency. Compact, transformer-free designs minimise energy waste and cooling load.
- Modular redundancy. N+1 architectures remove single points of failure and add capacity without more footprint.
- Heavy-load capable. Handles high crest-factor, non-linear and unbalanced loads with strong overload capacity.
- Serviceable & scalable. Hot-swap modules, smart paralleling and remote monitoring reduce MTTR.
