Balmar 24V Alternator Protection Module

Mounted conveniently on the rear of any alternator, the Balmar APM is designed to absorb voltage and current spikes that commonly occur in many onboard electrical distribution systems from intermittent connections, disconnects and over-voltage events.

Lithium battery adoption has introduced a new problem if a battery disconnects due to an internal fault or issue.

A battery-initiated disconnect during charging can induce a voltage surge which will damage the alternators rectifier diodes or internal regulator and render the unit inoperable.

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

The APM will clamp up to a 60 volt spike 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 and other devices on the electrical distribution network.

Visual and audible alarms indicate if the device has been compromised and needs replacement.
