Liebert APM is a transformer-free,
on-line UPS that allows quick and easy
capacity increases with the addition of
rack-mounted FlexPower™ core hardware
assemblies. The core assemblies allow
the UPS to expand for capacity or
redundancy in 15kW increments within a
single cabinet — 15kW to 45kW or 90kW.
No additional floorspace is required.
FlexPower core assemblies may even be
added without powering down connected
equipment.
On-line double-conversion technology
and internal redundancy combine to
provide protection from the full range of
power irregularities, offering the highest
availability.
With efficiencies of up to 94% at typical
load levels, Liebert APM offers one of the
industry’s highest efficiency ratings. The
UPS is even more efficient when sized in
accordance with present system needs,
instead of purchasing a larger capacity
system to anticipate future requirements.
