Albér BDS-256XL
Full-Scale Battery Testing And Diagnostics For UPS Systems
Albér BDS-256XL system
features include:
The Albér BDS-256XL Battery
Monitoring System Is Designed
For Today’s Large UPS Systems
Each Albér BDS-256XL Battery
Monitoring System continuously
diagnoses all critical battery
parameters such as cell voltage,
overall string voltage, current and
temperature. Automatic periodic tests
of the batteries internal resistance will
verify the operating integrity of the
battery. If resistance values exceed set
thresholds, the user can take the
proactive action of replacing the bad
battery before it affects the others in
the string, or before it causes
complete string failure.
By tracking internal resistance, the
system can predict and report failing
conditions prior to complete failure.
A time-to-go estimate algorithm,
which uses discharge parameters and
internal resistance readings, assists in
predicting remaining battery life.
Interface to the Albér BDS-256XL is
done with the Battery Monitor Data
Manager software package. The
Battery Monitor Report Generator
software creates reports from
collected data.
Monitor up to 256 cells/modules
per string. 2 volt cells, NiCd cells,
4 volt, 6 volt, 8 volt, and 12 volt
modules supported.
Modular design easily expands
to monitor an unlimited number
of strings.
Overall voltage, cell/module
voltages, current, and temperature
are continuously scanned every
four seconds and compared with
user-programmed alarm levels.
At user-selected intervals,
automatic pro-active internal DC
resistance tests are performed and
compared to user-programmed
alarm levels. All data is saved for
automatic retrieval.
At user-selected intervals, overall
voltage, cell/module voltages,
current, and temperature readings
are saved for automatic retrieval.
Discharges are automatically
detected and data saved for
retrieval. Discharges can be viewed
in real time locally or remotely
during the event or later replayed in
real or accelerated time.
Alarm events trigger an indicator,
dedicated contact closure,
programmable contact closure and
automatic dial-out notification. Can
be user-set to page, fax, print,
and/or sound audible alarm.
Industry standard MODBUS
protocol interfaces to third party
building management systems via
RS-232/USB and Ethernet.
Albér technology by
Emerson Network Power
Emerson Network Power offers the
latest in UPS battery monitoring
technology with products by Albér —
a leader in the field since 1972. Albér
technologies by Emerson Network
Power are designed to prevent
battery failure, optimize useful
battery life, reduce maintenance
cost and increase safety.
Communicates with an external
computer via R-S232/USB or
remotely through internal modem.
Optional TCP/IP interface for
network or Internet
communication via MODBUS
or SNMP.
When used in conjunction with
the MPM-100, virtually all battery
configurations can be managed
on-site and/or remotely with one
software package.
Windows-based software for realtime viewing, automatic data
collection, data analysis, and
report generating.
Digital input/output option permits
monitoring up to 16 inputs and up
to 8 user-programmed outputs.
Monitor Load Control option
enables the monitor system to
control an Albér Continuous Load
Unit (CLU) for performing battery
capacity testing.
