Battery Monitoring With Remote Access   Telecom Cell Sites Power Ditribution Substations Railway Signalling Systems The EMS430 Battery Supervisor is a din mounted module which monitors the performance of 12, 24 or -48 volt batteries. Battery current, voltage and state of charge are monitored. Battery ambient temperature can be monitored. An isolated RS485 link is provided for linking to supervisory equipment     Accurately measures incoming and outgoing battery current Accurately measures battery voltages for 12, 24 or -48 volt DC systems. Provides energy in versus energy out (Amp Hours) for each charge/discharge cycle. Provides an output for charger disconnect on high battery volts alarm, giving protection against overcharging in the event of charger malfunction Provides an output for controlling an EMS350 (or similar) controlled generator-based charger based on low battery volts or low residual battery energy. This can be used to minimise deep battery cycling and consequent battery stress. Maintains a history of the previous discharge and charge cycle information at intervals of 1 minute. Provides connection capability to single wire bus temperature monitors (EMS410) for monitoring battery room temperatures and assisting in the detection of overheating battery cells. Provides addressable isolated RS485 connectivity for connection to a multi-node Modbus network Interfaces to the EMS420 site supervisor for local status display and setup. Together with the EMS420 it can be remotely monitored and polled for logged performance data using PowerConfig, PowerLink or PowerLink Lite monitoring software.   © 1998 EMS
