The wireless Staco FirstLineBMS Battery Monitoring System continuously monitors UPS batteries and provides real-time information, ensuring that batteries are ready when needed to support mission critical functions. Information is displayed through curves and bar graphs on the FirstLine BMS easy to read 6.4-in. LCD touch screen monitor. This easy-to-install battery monitoring system measures and records critical elements including battery cell voltage, battery string voltage, battery string current, battery room temperature, battery cell impedance, as well as battery terminal temperature. Real-time status is compared to battery configuration settings and network parameter settings, with deviations recorded in an events log and used to trigger e-mail or dry contact alarms.
