Emerson 40-120KVA - Manual

1
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.
