Mastervolt 2503 IG Load Separator

Keep Your Essential Batteries Charged and Protected with the MASTERVOLT 2503 IG Load Separator

The MASTERVOLT 2503 IG Load Separator is a critical component for any system with multiple batteries that need to be charged from a single alternator. This intelligent device ensures your starter battery remains charged and ready to go, while simultaneously allowing for optimal charging of your service battery bank.

Never Worry About a Dead Starter Battery Again

The primary function of the 2503 IG Load Separator is to prevent the discharge of your starter battery by isolating it from the service battery bank. This means that even if you heavily discharge your service batteries, your engine will always have enough power to start.

Efficiently Charge Multiple Battery Banks

This separator utilizes a voltage-sensing relay to connect and disconnect the batteries. When the alternator voltage reaches a pre-set level, indicating charging, the relay closes and allows the alternator to charge both the starter and service batteries. Once the voltage drops, indicating the alternator is no longer charging, the relay opens and isolates the batteries, preventing any discharge from the starter battery.

Ideal for a Variety of Applications

The MASTERVOLT 2503 IG Load Separator is perfect for a wide range of applications, including:

* Boats and Marine Vessels: Ensure your engine starts reliably while powering onboard electronics and appliances.
* RVs and Campers: Keep your living space powered without draining your vehicle´s starting battery.
* Off-Grid Systems: Maintain a dedicated battery for critical loads while charging a separate bank for general use.
