Albér BDS-40

Comprehensive UPS Battery Diagnostic System

Albér BDS-40 Battery
Monitoring System Is Built
For Today’s UPS Battery Cabinet
System Configurations

Designed and optimized for UPS
systems using 12 volt sealed batteries,
the Albér BDS-40 is designed to be
mounted on top of the cabinet and
uses custom cables with each
connection point identified to the
specific battery. Installation is
quick and easy.

Each Albér BDS-40 unit will monitor
all the batteries in one cabinet, up to
40 jars. Two different units are

Easy To Use

’s BDS system makes

Albér
hard-to-interpret data much more
understandable and manageable.
The Battery Monitor Data Manager
Computer Software is included with
every system. With the software you
can program thresholds, identify
problem batteries by making bar
graphs turn red, triggering alarms and
distribute alerts to e-mail lists as soon
as abnormal conditions are detected.
The report has built-in decision
support that analyzes the data and
provides suggestions for the best
cause of action.

Early Warning For Battery
Problems.

Like all Albér monitors, the Albér BDS­40 uses a patented Internal DC
Resistance test method that bypasses
the limitations of outdated AC based
impedance testing. By tracking
internal resistance, the system can
predict and report failing conditions
prior to complete failure. A time-to­go estimate algorithm, which uses

ischarge parameters and internal

d

e readings, assists in

The Albér BDS-40 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. An alarm sounds for any out­of-tolerance condition. If resistance
values exceed set thresholds, the user
can take proactive actions.

Sealed batteries are sensitive to temperature and float voltage settings.
Monitoring these conditions can considerably extend useful battery life.

An Albér 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
confidence by knowing their true internal condition.

It is essential to detect deterioration at an early stage to prevent
catastrophic failures when dealing with 12 volt 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 influenced
by ripple and thus provides data that is repeatable and reflects the true
condition of the battery.
