Emerson 60HZ Dépliant

The Liebert NX is a true on-line, double conversion, 

three-phase UPS system that delivers complete, 

centralized power protection for mission-critical 

systems. 

Designed to meet the high availability power needs 

of a wide variety of IT applications, the UPS com-

bines a rack form factor, advanced operating fea-

tures and low cost of ownership.
• Increases growth flexibility with Softscale™ 

technology, plus the ability to parallel modules 

for increased capacity and redundancy.

• Achieves higher availability by reducing the 

number of UPS units required to power your 

data center.

• Reduces total cost of ownership through the use 

of longer life batteries and simplified preventive 

maintenance.
