Alternators can be subjected to voltage spikes caused by lithium battery shutdowns, intermittent connections and other over-voltage events. Balmar has introduced a robust Alternator Protection Module which helps protect the alternator’s diodes and internal regulator against spikes (clamping up to 60V) and sustained over-voltage conditions (beginning around 20V) for the 12V version. The APM can absorb multiple surges of such energy,...
