The ProCon VSR is the next grade up from the ProCon IF. The VSR does not require an ignition feed and is totally automatic. When the voltage of
battery 1 (e.g. starter battery) exceeds 13.3V the ProCon VSR assumes that the charging device (alternator / battery charger) is active - this causes
the relay to engage - thus charging battery 2 (e.g. auxiliary battery).
Conversely, when the voltage across battery 1 drops below 12.9V (due to battery discharge) the relay disengages and prevents charge being drawn
from battery 1 to battery 2. The ProCon VSR therefore 'saves the day' by prioritising the more important battery bank (starter) so the engine can
always be started.
