Product description

Monitoring of battery systems to find voltage inversions of single cells, internal short circuits and sulphating.
The middle connection of a Battery system is connected to terminal “M” of the BA 9054/331. If the two parts of the voltage differ more then the adjusted value for 10 s, the output relay trips. It trips also on broken wire on terminal “M”. The test button allows a test of the unit. It has to be pressed for at least 10 sec.
