Blue Sea ML-ACR Automatic Charging Relay

Regular price €303,54
Regular price Sale price €303,54
Tax included.

Two battery banks, one intelligent relay: The Blue Sea ML-ACR automatically connects your batteries as soon as charging starts – and reliably disconnects them as soon as you start the engine or consumers draw power. This keeps the starter battery always fit, without you having to touch a switch.

Tip: Use the configurable Start Isolation (SI) if you have sensitive navigation or entertainment electronics on board – this disconnects these consumers from the engine circuit for a short time during starting and protects them from voltage spikes.
