Product Details

The Balmar APM-48 Alternator Protection Module is designed to protect 48-volt marine alternators from damaging voltage spikes and load dump conditions. This essential device monitors system voltage and disconnects the alternator from the batteries when potentially harmful conditions are detected, preventing costly alternator failures.

Key Features:

  • Designed specifically for 48V marine electrical systems
  • Protects against voltage spikes and load dump scenarios that can destroy alternator diodes
  • Automatic disconnection when dangerous voltage levels are detected
  • Compact, weather-resistant construction suitable for harsh marine environments
  • Essential protection for high-output marine alternators in 48V applications

The APM-48 is particularly valuable in systems where batteries may become accidentally disconnected while the alternator is charging, a condition that can generate voltage spikes exceeding 100 volts and instantly damage the alternator. This module provides peace of mind and extends the service life of your charging system components.

Great Website.

Just as the name implies, simplicity at its finest.

I am really liking the West System Epoxy products.

Great
