Preventing battery failure is essential for delivering maximum availability. Liebert products incorporate Alber technology to extend battery life, reduce maintenance cost and increase safety.




Alber Cellcorder CRT-300
The Albér Cellcorder CRT-300 cell resistance tester displays and records cell float voltage, internal cell resistance and intercell connection resistance. The portable unit includes a memory card, backlit graphical reflective LCD display for better contrast and specially designed cables and clamps with interchangeable jaws for different battery post designs. A built-in infrared port provides wireless communications to printer, PDA, DMA-35N Hydrometer or laptop computer. An optional internal modem is also available. The Albér Cellcorder can be used on single cell or multicell modules. Readings can be transferred to a PC for analysis and report generation.

Liebert MPM-100 Battery Monitor
The MPM-100 is a battery diagnostic system designed for lower cell count applications such as telecom or stationary battery systems. It identifies potential problems by continuously monitoring parameters such as cell voltage, overall string voltage, current and temperature. Automatic periodic tests of battery internal resistance will verify the operating integrity of the battery.

The MPM-100 accommodates more than 50 different battery configurations and can be modified for nonstandard configurations. With its automatic polling and data transfer algorithms, the MPM Battery Monitor Data Manager (BMDM) software enables a central computer to manage over alone operation, and can communicate with an automatic callout system upon alarm or discharge current sensing. Connection to a monitoring site may be via the network or through the internal modem, 1000 battery systems.

The system is available in either 19” or 23” rack mount, and can be configured for most power, telecom, and cellular applications. The MPM-100 has a self-contained processing unit for stand- or locally to a computer via the RS-232 port.

Liebert BDS-40 Battery Monitoring System
Designed and optimized for UPS systems using 12 volt sealed batteries, the Liebert BDS-40 is designed to be mounted on top of the battery cabinet and uses custom cables with each connection point identified to the specific battery. The BDS-40 continuously diagnoses all critical battery parameters such as cell voltage, overall string voltage, current and temperature.

Automatic periodic tests of battery internal resistance will verify the operating integrity of the battery. Each BDS-40 unit will monitor all the batteries in one cabinet, up to 40 cells.
Two different units are available: The BDS-40 Base Unit is the central point where UPS-supplied power and communication connections are made. Each additional battery cabinet in the system may then use a BDS-40 Plus Unit, which transfers the data to the Base Unit for alarm and data storage. Each Base Unit can manage up to five Plus Units for a total of six battery cabinets. There is a choice of an integral Ethernet network card and/or a dial-up modem as standard.

Liebert BDS-256 Battery Monitoring System
Designed for large UPS systems, each BDS-256 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. Interface to the BDS-256 is done with the Battery Monitor Data Manager software package. The Battery Monitor Report Generator software creates reports from collected data.
