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, and can absorb
surges in excess of 200 amps without failure to continually protect your
alternator. Visual and audible alarms indicate if the device has been
compromised and needs replacement.
Balmar APM devices provide intelligent, robust, solid state protection in
a small, easily mounted package at the rear of the alternator between the B+
and B- terminals. Balmar APM devices can be used to protect all alternator
brands.
