Mastervolt Battery Mate 1603 IG Isolator - 120A, 3 Bank

The Battery Mate 1603 IG Isolator is a high-performance solution designed for marine and boating applications, enabling efficient charging of multiple battery banks simultaneously. With a robust 120 Amp capacity and support for up to three battery banks, it ensures reliable power management for your vessel's electrical systems.

Key Features

• High Capacity: 120 Amp rating supports multiple battery banks, ideal for marine environments.
• Three Battery Banks: Manage and charge up to three separate batteries efficiently.
• Advanced Technology: Utilizes electronic components and MOSFETs for superior performance over conventional isolators.
• Minimal Voltage Loss: Ensures fast and complete charging with negligible voltage drop between the alternator and batteries.
• Universal Compatibility: Works with any type of alternator or battery charger, suitable for both new and existing systems.
• Easy Installation: Fits standard DIN rails for hassle-free mounting on your vessel.
• Additional IG Contact: Supports external excitation or voltage sensing for standard alternators requiring it.

Why Choose Battery Mate 1603 IG?

Unlike traditional diode splitters, the Battery Mate 1603 IG Isolator employs electronic technology with MOSFET transistors, providing consistent charging even with multiple battery banks. This advanced design compensates for voltage variations, ensuring that each battery receives the optimal charging voltage without additional adjustments to the alternator.

Technical Specifications

Installation Guide

The Battery Mate 1603 IG Isolator is designed for straightforward installation on a standard DIN rail, commonly found in marine electrical panels. Connect the input side to your alternator or battery charger, and then attach up to three battery banks to the output side.
