MPS 500-800KVA |
Sentry MPS is
an on-line, double conversion UPS of class
VFI SS 111 in accordance with IEC EN 62040-3
with an internal Inverter and output transformer.
This solution is particularly suitable for
high-level applications where the immunity
of the load from the mains is a real issue.
The Sentry MPS 500KVA to 800KVA range is available
in the following ratings: 500, 600 and 800KVA,
each of these are offered in four versions
to better match the market requirements:
• MPS Plus
• MPS

Clean Input
Thanks to the low input current distortion of up to
3% (MPS Sinus ), Sentry MPS
represents a load with sine wave input for the source
reducing any interference to the other loads connected
on the same busbar. For all versions the power factor
is > 0,9, while the MPS Sinus version guarantees a
power factor up to 0,95 even at partial loads. This
means that it is unnecessary to oversize the connection
cables and the rating of the upstream MT/BT supply
transformers thereby reducing the installation and
ownership cost.
Motor Generator friendly
The low input current distortion, the high input power
factor, the progressive start-up of the rectifier
(settable) and the battery recharge inhibition makes
Sentry MPS ideal for use in conjunction with a smaller
size generator set, in some cases close to the UPS
rated power.
Battery care system
Sentry MPS includes the “Battery Care System”
which manages the batteries in order to obtain best
performances and prolonged operating life:
• Absence of the ripple current with battery
charged
• Charging on two voltage levels to optimize
the recharge current and reduce the times required
to restore capacity
• Recharging voltage with
temperature compensation and protection against deep
discharges to protect the battery, minimise aging
phenomena and prolong the real battery life
•
Max recharge time block to reduce electrolyte consumption
to improve the lifetime of the VRLA batteries
• Battery test to check the performance and make sure
the battery is always ready to work
Sentry MPS is also compatible with different battery
technologies: open lead acid, AGM and Gel VRLA, NiCd.
Battery recharge capability
Sentry MPS is designed to supply the nominal load
and recharge the batteries. At partial loads the spare
power can be used to recharge the batteries, therefore
Sentry MPS can recharge batteries with 3 hours back
ups time in only 10 hours .
Flexibility
Sentry MPS Series is ON-LINE double conversion design
but can also operate in:
• Smart Active
• Stand-by-Off, suitable for Emergency Escape Light
(CSS – Central Supply System), as per standard EN50171.
All models can be used as frequency converter - 50/60Hz
and vice versa.
Expandability
The units can be connected in parallel - up to eight
modules - to increase power availability or the redundancy.
The single module or the system can be expanded at
any time depending on the power demand without any
impact on the initial investment. Thanks to the peculiarity
of the “Hot System Expansion” feature, the
additional unit can be connected in parallel while
the other units are on-line and supplying regular
power to the load. The new UPS in on-line and will
receive the updated information automatically.
Dual Bus System
The Dual Bus System supplies the priority loads from
two independent sources. This configuration increases
the redundancy and availability level of a multi-module
configuration. Each bus may consist of a single module
or up to 8 modules in parallel, kept in synchro by
the optional UGS device (UPS Group Synchroniser).
This allows the use of the STS (Static Transfer Switch)
dowstream to power the loads.
Dynamic
Dual Bus System
Two independent systems set in Dual Bus configuration
can be merged together at any time for system expansion
or maintenance. This provides a lot of flexibility
in your installation in case of maintenance or when
it is necessary to change the redundancy level of
both systems. The safety of the operations is guaranteed
by the optional device PSJ.
Ease
of installation
Sentry MPS has a very small footprint (only 0,64mq
for 200kVA). The front access makes it very easy for
all servicing operation while upward ventilation makes
positioning against the wall possible.
Advanced
communication
MPS Series is delivered with the AROS Watch&Save 3000
Software package and is compatible with PowerNETGuard
or Teleguard for remote maintenance. The UPS is supplied
with two RS232 outputs for remote monitoring and a
wide range of communication cards:
• Netman
102 Plus (SNMP Agent)
• Multicom 302 (MODBUS/JBUS)
• Multicom 352 (Serial Duplexer)
• Profibus Converter
• Multi I/O ( Modbus Converter of the alarms coming
from outside the UPS cubicle)
• 2 alarms cards
with relay contacts, alarms are user-programmable
through the software.
For more information on the Communication Cards see
the CONNECTIVITY area
Application
Sentry MPS guarantees maximum protection and
quality of power supply for any type of load and in
particular for “mission critical” applications, security
and electromedical systems, industrial processes and
telecommunications.
