Flexa – Modular Uninterruptible Power Supply

Modular UPS 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! You then have the choice to size the batteries according to the backup time you require.

A complete solution with high-temperature batteries has been designed by the Helios team. This solution is aimed to provide more than 8 hours of autonomy. Check out the datasheet above you will find more information about it.

The system is designed for harsh environment operating up to 60°C (with a derating starting at 40°C). Despite the high conversion efficiency of the modules, the thermal design has been studied to optimize passive cooling. As a result, you only need to dissipate one third of the remaining heat in your integrated solution.
