     Space saving

     Reduced footprint
     Valuable floor space maximised

     With a footprint of only 0.4m2 at 50 kVA,
     the Kohler PW 5000/TP has a power
     density of up to 100 kW/m2. As a result,
     substantial and valuable space savings
     are achieved even at the highest power
     ratings.

Innovation with purpose.

Designed with a clear goal to define that
reliability does not require excess, and
high power can exist alongside efficient
use of energy, the MF1500 DPA modular
UPS system combines proven DPATM
technology with the latest advances in
components and software.

Innovative, vertical slide-in modules
enable resilient, high power density
protection by reducing UPS footprint up
to 45% over traditional approaches,
without compromising access for
installation and maintenance.

That protection is achieved with best-in-
market 97.4% VFI energy efficiency,
reducing environmental impact,
optimising PUE measures and delivering
significant financial savings in energy
and cooling costs.

for total power protection.
The battery plays a key role in the overall
reliability and availability of a power
protection system. It supplies the energy
required by the critical load in the event
of a mains utility failure or when the input
mains voltage and frequency are outside
the acceptable values. Moreover, the
battery represents an important share of
the total cost of the UPS, and therefore
battery care and management are of
paramount importance when a UPS is
designed.

Kohler Uninterruptible Power provides a
range of remote monitoring and
diagnostics services to provide early
fault detection and prevention. Battery

Impedance testing

Our impedance testing provides a
means of assessing the internal
condition of batteries. Almost any
battery problem will lead to an increase
in internal impedance. Recorded at
regular intervals, impedance testing will
track battery condition and enable
end-of-working-life prediction. This
service is included as part of the Battery
Monitoring system or can be purchased
separately.
