Liebert Nfinity
®
On-Line UPS:
4-20 kVA, 1-phase
The Liebert Nfinity power system is a scalable 4
to 16 kVA or 12 to 20 kVA UPS designed with N+x
parallel redundancy to provide a fault-tolerant
network of power protection.
The modular design of the Liebert Nfinity power
system was devised to provide easy scalability to
users as their power demands grow. Configurations
can be cost-effectively upgraded without
re-investing in a new system or installation.
The Liebert Nfinity is a true on-line,
double-conversion UPS that provides 100% power
conditioning, zero transfer time to battery, no
change in output voltage and better transient
suppression than line-interactive units.
Its unique frame design houses all of the modular
system components, including 4 kVA power
modules, battery modules and system control
modules. By simply installing additional power
or battery modules, you can expand your current
system, extend backup runtime or add redundancy.
Intelligent power modules provide protection
from all power aberrations, and a patent pending
electrical current-sharing technology provides
equal distribution of power among all modules.
The IntelliBattery
™
modules utilize multiple
sensors to continuously monitor battery voltage,
current and temperature to determine and
predict performance.
The IntelliControl
™
module works with the user
interface to provide vital information about the
condition of the power and battery modules.
A True On-Line System That Delivers
Continuous, Regenerated Sinewave
Output Power
