Flexa – Modular Uninterruptible Power Supply

Single Phase Output from  3kVA up to 12kVA

This solution is compatible with 230 Vac loads and 48 Vdc batteries (Lead-acid or NiCd). The modularity allows to increase the power output step-by-step from 3 to 12 kVA. Fully equipped, this rack system can reach the power density of 12 kVA in only 2U high offering the highest one in the market.

Rack Integration

The complete solution offers, in only 5U high, the converters, the AC distribution, the manual by-pass and the monitoring solution (Inview S). Simply connect your batteries and your loads and the all-in-one solution is ready to secure your most critical assets!
