Product Details

The Balmar APM-12 Alternator Protection Module delivers best-in-class surge protection for 12-volt alternators using advanced automotive-grade technology. This essential protective device safeguards your alternator from voltage spikes and damaging surges that can occur during normal marine and automotive electrical system operation.

Key Protection Features:

  • Guards against battery switch disconnects while alternator is charging
  • Protects from lithium battery BMS (Battery Management System) sudden disconnects
  • Shields alternator from voltage surges generated by solenoids, battery combiners, starters, and other high-current motors
  • Excels at handling both short-duration spikes and longer-duration surge events where competitive products fail

The APM-12 is engineered specifically for 12-volt charging systems and provides critical protection for high-output alternators, particularly important in marine applications with lithium battery banks where BMS disconnects can create dangerous voltage spikes. Easy to install inline with your alternator's output, this module acts as an insurance policy for your charging system investment.
