Alternator Protection Module: APM-24



Part #: APM-24

Alternator Protection Module, 24V

The Balmar APM provides best-in-class surge protection using the latest technology developed for the automotive industry. It can protect alternators from damaging effects:

• Battery switch disconnects
• Lithium battery BMS disconnects
• Surges from solenoids, combiners, starters and other motors.

The Balmar APM excels in both short duration and longer duration spikes, where other products fail.

More Information

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 to protect the alternator’s diodes and internal voltage 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.  Balmar APM devices meet ISO 16750-2 for Load Dump Protection and ISO 7637-2 for Surge Protection.
