Balmar Alternator Protection Module APM12 - 12V

The Balmar Alternator Protection Module APM12 is essential for marine and boating applications, safeguarding your vessel's alternator from voltage spikes and ensuring reliable electrical performance even in challenging conditions.

Protect Your Alternator from Voltage Spikes

Alternators on boats are vulnerable to voltage spikes caused by lithium battery shutdowns, intermittent connections, and other over-voltage events. The Balmar APM12 offers robust protection by safeguarding the alternator’s diodes and internal voltage regulator against these voltage anomalies.

Key Features

• High Voltage Clamping: Clamps voltage spikes up to 60V to protect critical alternator components.
• Sustained Over-Voltage Protection: Begins protection at approximately 20V for the 12V version.
• High Surge Absorption: Capable of absorbing multiple surges exceeding 200 amps without failure.
• Intelligent Alarms: Visual and audible indicators alert you if the module is compromised and needs replacement.
• Universal Compatibility: Protects all alternator brands used in marine applications.
• Compact Design: Easily mounts at the rear of the alternator between the B+ and B- terminals.
