SBS's portable battery monitor is compact, small and lightweight, but packs everything you need to protect and diagnose your essential BUS.  Our portable battery monitor automatically indicates the instant a ground occurs.  You can find the exact location of the ground anywhere in the line quickly, using the included hand-held fault locator.

The highly accurate DC voltage meter relay provides voltage readings of battery, + or -BUS to ground, and ground fault voltages for protection of the essential BUS.  The ground fault relays indicate the ground anywhere in the system, whether on the "+" or the "-" side.  Over/Under voltage relays are also provided.  Fail safe operation of the under voltage relay operates correctly down to zero volts.  Time delay, which can be set from 5 to 60 seconds, is provided to avoid nuisance alarms.

Front panel relay contacts can be connected to any type of remote indicators such as alarm contacts.  The system can also be interfaced with virtually any computer system without special software.
