Battery Monitoring
For Business-Critical Continuity™
Alber® BDSi
™
Battery Monitoring System For UPS Battery Cabinet Integration
Alber technologies by Emerson Network Power are designed
to prevent battery failure, optimize useful battery life, reduce
maintenance costs and increase safety.
The Alber BDSi is designed specically for factory integration
into Liebert UPS battery cabinets for 12 and 16 volt battery
applications. A factory installed monitor continuously scans
and reports all critical battery parameters, providing detailed
reports that allow proactive battery management. The result:
a reliable, effective system that is efcient to deploy.
Key Features of Alber BDSI:
Flexibility
Web-based monitoring interface allows
easy user access to data and reports
A single controller unit communicates
with up to six DCM/LM units, for
monitoring of a total of six battery
cabinets
Factory installed, or eld installation
kits available for Liebert UPS battery
cabinets
Higher Availability
Alber BDSi Battery Monitoring provides real time
information for proactive battery management
Factory installation and testing ensures
proper operation at start up
Data tracking and detailed reports
allow analysis for proactive prevention
of battery failure
Lowest Total Cost of Ownership
Replace batteries when they are at
the end of their service life — not
by calculations that could result in
premature or late replacement
Complete factory installation
eliminates requirement of eld
installation
Ideally Suited for:
Liebert UPS external battery cabinets
Liebert NXL
Liebert NX
Liebert APM
Liebert 16V battery cabinet
Simple hardware conguration
The Alber BDSi system consists of two units: a Controller, and a Data Collector
User-friendly software
provides easy to
interpret data
Battery Monitor Data
Manager (BMDM) Computer
Software is included with
every system. With the
software you can program
thresholds, view graphs
and trends to identify
failing batteries, set alarms
notications and distribute
reports. The reports have
built-in decision support
that analyzes the data and
provides suggestions for the
best corrective action.
Module/Load Module (DCM/LM).
The DCM/LM unit collects individual cell
data and performs the resistance test.

Easy to interpret graphs
make data understandable
and manageable
The rst battery cabinet includes both an Alber BDSi Controller and Alber BDSi
DCM/LM. Each additional battery cabinet uses only an Alber BDSi DCM/LM unit
linked to the single Controller Unit in the rst battery cabinet. A Controller can
communicate with up to six DCM/LM units or battery cabinets. Communication
options are by Ethernet network card, RS-232 or dial-up modem.

BDSi Specications
Sealed batteries are sensitive to temperature and float voltage settings.
Monitoring these conditions can considerably extend useful battery life.
A Liebert battery monitor provides the user with detailed information, allowing for cost savings by optimizing useful
battery life. Instead of waiting for an inevitable failure or replacing batteries prematurely to prevent problems, you
can continue to utilize your batteries longer and with condence by knowing their true internal condition.
It is essential to detect deterioration at an early stage to prevent catastrophic failures when dealing with sealed
batteries. This makes measurement technology the most important consideration when selecting a monitoring
system. Other battery monitors’ internal ohmic readings become inconsistent as the UPS load varies because of
variations in AC ripple on the battery. The Albér DC resistance test method is not inuenced by ripple and thus
provides data that is repeatable and reects the true condition of the battery.
