0.9 output power factor, and lightweight,
compact design, the DiamondPlus™ is
both green and smart. It gives energy
conscious users an alternative UPS
solution to meet their needs. Both the
1100A (10-50 kVA) and the 1100B (50-80
kVA) configurations are upgradeable in
10 kVA increments.
The Diamond Plus™ 1100 UPS Series
is an optimal solution for protecting
power equipment. As a true on-line
three phase double conversion UPS
system, customers can be assured that
their needs are met for back-up power.
With energy costs ever increasing in
the marketplace, the DiamondPlus™
1100 provides a reduced Total Cost of
Ownership with its compact footprint,
high energy efficiency and flexible
modular design, among other factors.
With reliable back-up power in place,
our customers can have complete
piece of mind.
Both have has fully-digital screens and
front access, which allows for easy
monitoring and faster repair times.
The DiamondPlus 1100’s power and
battery modules are “hot swappable”
