The Balmar APM-12 is an Alternator Protection Module designed specifically for 12-volt systems. It provides surge protection for alternators against damaging effects from events like battery switch disconnects, lithium battery BMS (Battery Management System) disconnects, and surges from solenoids, combiners, starters, or other motors. It uses solid-state technology to create a short circuit that grounds the alternator output during such events, preventing uncontrolled voltage spikes that could cause failure.
