ABSOLUTE PROTECTION
Thanks to the double conversion on-line
technology achieved entirely with IGBT
and DSP (Digital Signal Processor)
control, the Sentry MPS-HP series
guarantees maximum protection as well
as high quality power for any type of IT
and industrial load. It is especially suited
for mission critical applications and is
classed VFI SS 111 (Voltage and
Frequency Independent) in compliance
with IEC EN 62040-3 standards.
This series, available in 100 to 250kVA
models, has been designed using a new
configuration that includes an IGBT
rectifier with sinusoidal input current in
place of the traditional thyristor rectifier.
ZERO IMPACT SOURCE
Sentry MPS-HP is a further evolution of
the Sentry MPS series with the added
advantages offered by an IGBT-based
rectifier assembly. This feature further
reduces the impact of the UPS on the
local supply and simplifies installation
where there is limited power capacity in
the form of available electrical supply
rating or generator size. Sentry MPS-
HP is classed as a “Zero Impact
Source” and provides:
• low input current distortion – less than
2,5%
• high input power factor 0.99
• power walk-in function that ensures
progressive rectifier start up
• delayed start up phased with the
return of mains power supply, when
several UPS are connected in the
system.
Sentry MPS-HP also performs the role
of a high performance filter, protecting
its upstream power supply sources
from any harmonics and reactive power
generated by the loads powered.
BATTERY CARE SYSTEM
Sentry MPS-HP uses the Battery Care
System, also available on the traditional
Sentry MPS models, which optimises
battery performance in order to extend
the battery life for as long as possible.
