LEM Announces Sentinel III Portfolio of Comprehensive Battery Monitoring Components

Key Points:

o Advanced Battery Monitoring solution combines state of the art monitoring featuring impedance measurement with ease of use and fast installation

o Remote system monitoring via secure internet connection

o DIN rail mounting and external temperature patch reduces time required for installation

o Components solution allows flexible configuration for OEMs, VARs and System Integrators

GENEVA, Switzerland - November 24, 2009 - LEM S.A., the world's leading manufacturer of isolated current and voltage measurement components, announces Sentinel III; an advanced set of components for a battery monitoring solution that addresses the needs of Uninterruptible Power Supplies (UPS) and battery provider Original Equipment Manufacturers (OEMs), as well Value-Added Resellers (VARs) and Systems Integrators. Sentinel III components are used to create a simple to install and intuitive solution for continuous battery monitoring within mission critical installations such as hospitals, airports and data centers.

The Sentinel solution combines transducers, data loggers and software components to create a comprehensive, yet simple and cost effective, Standby Battery Monitoring solution (SBM). In order to extend the functionality of its existing Sentinel, LEM has developed the S-BOX; an advanced data logger featuring an embedded web server which enables administrators to monitor installations remotely. The S-BOX state of the art measurement and data logging features include Bloc, String and Battery Voltage measurement, Bloc temperature and impedance measurement, discharge performance and discharge/charge current. The S-BOX also measures ambient temperature, a key factor affecting battery life.

The new Sentinel transducer is designed to reduce installation time, offering DIN-rail mounting and an external temperature patch. Users can set up an alarm for each of the parameters measured by the transducers connected to the S-BOX. As well as instant alarms the S-BOX can also provide a weekly report to the administrator, containing all daily measurements and critical system information.

The S-BOX is DIN rail mounted for easy installation and includes software for simple configuration and remote monitoring. Further information about the Sentinel SBM, including a PDF brochure and informational video, can be found on the LEM website
