Sentry MPS
Three-phase output
QUALITY POWER SUPPLY
SENTRY MPS is an on-line double
conversion UPS (VFI SS 111 in
accordance with IEC EN 62040-3) with
a transformer isolated inverter. With a
compact footprint and high power quality
output, SENTRY MPS is designed to
protect “mission critical” applications
including data processing,
telecommunications, industrial
processes, security and electro-medical
systems.
BATTERY CARE SYSTEM: MAXIMUM
LIFETIME POTENTIAL
Traditionally, when a mains supply is
present the UPS charges its batteries.
Battery power is used for the inverter
should the input supply fail. Efficient
battery management and care is
therefore essential to the overall
performance of the UPS in an
emergency. The SENTRY MPS Battery
Care System consists of a range
of features designed to provide
optimum performance and enhanced
operating life:
• Dual level charging regime to
optimise recharge currents and lower
recharge times;
• Temperature compensation and deep
discharge protection to reduce overall
battery aging;
• Charge blocking system to reduce
electrolyte consumption and lengthen
the life of VRLA batteries;
• Predictive battery testing to spot
potential battery deterioration and
failure.
SENTRY MPS is also compatible with
different battery technologies: open-
vase lead acid and AGM and Gel
VRLA, NiCd.
MINIMUM INPACT ON SUPPLIES -
EASY SOURCE
SENTRY MPS technology removes the
problems of over sizing downstream
power sources, whilst improving load
power factors and current harmonics.
The UPS features the latest input current
absorption techniques including
progressive rectifier start-up and the
option to reduce battery charging
currents. These features make SENTRY
MPS one of the most generator
compatible and environmentally friendly
UPS available.
