m-Series Automatic Charging Relay – 12/24V DC 65A

SKU: BSS7601

The Mini Automatic Charging Relay (M-ACR) is designed to manage the charging current from alternators up to 65 Amps found on most outboards and many inboard engines.

Start Isolation (SI) protects sensitive electronics by temporarily isolating house loads from the engine circuit during engine cranking, protecting the house circuit from voltage sags and spikes.

The compact design allows for three mounting styles: surface, rear, or panel mount. The M-ACR is also available as a module in a Custom 360 Panel.

**The maximum current a switch is designed to conduct for an indefinite period.
***The maximum amount of current a switch is designed to carry for a minimum of a designated period of time.
****As a safety feature, some ACRs prevent combining into a severely discharge battery. A dual-sensing ACR will monitor the voltage on both batteries and will not connect if either battery is below the undervoltage lockout level. Use caution when combining into a battery with extremely low voltage, because this might represent a faulty battery or a problem elsewhere in the system.
