Balmar APM-24 Alternator Protection Module 24V Marine Surge Protector

The Balmar APM-24 Alternator Protection Module delivers best-in-class surge protection for 24-volt marine electrical systems using advanced automotive-grade technology. Designed to safeguard your alternator from potentially catastrophic voltage spikes, this essential protection device prevents damage that can occur during common marine electrical events.

Key Protection Features:

• Protects against battery switch disconnects while alternator is charging
• Guards against sudden Lithium battery BMS (Battery Management System) disconnections
• Shields alternator from voltage surges generated by solenoids, battery combiners, starter motors, and other high-current devices
• Superior performance during both short-duration spikes and extended surge events

The APM-24 utilizes the latest surge suppression technology originally developed for demanding automotive applications, providing reliable protection where other products may fail. This module is specifically engineered for 24-volt systems and is an essential component for protecting expensive alternators in marine environments, particularly in vessels equipped with modern Lithium battery banks that can disconnect without warning.
