Victron Energy ARG120201020R

The Victron Argodiode 120-2AC battery isolator efficiently charges two batteries simultaneously from a single alternator, ensuring no discharge between batteries. With Schottky diodes, it minimizes voltage drop for optimal performance, making it an essential component for maintaining battery health in automotive and marine applications.

Product Features

Simultaneous Dual-Battery Charging

This isolator allows for the efficient charging of two batteries at the same time using a single alternator, safeguarding the starter battery from being depleted when the accessory battery is in use.

Reduced Voltage Drop

Incorporating advanced Schottky diodes, the product ensures a minimal voltage drop, enhancing charging efficiency. At low current, the drop is around 0.3 V, increasing only slightly to 0.45 V at rated output.

Compensation Diode Inclusion

Equipped with a compensation diode, this feature slightly boosts alternator output voltage, counteracting the small voltage drop through the isolator for maximum charge efficiency.

Alternator Energize Input

This isolator includes an energize input for alternators needing a DC signal to start. This feature ensures reliable alternator performance even when the isolator is in place.

Sturdy and Adaptable Design

Built with robust materials and designed for straightforward installation, it fits well in both automotive and marine electrical systems, promoting extended battery longevity and performance.

How It Works

The Argo Diode Isolator effectively channels power from a single alternator to multiple batteries, without linking them together. It cleverly uses diodes to maintain battery separation, preventing cross-discharge and providing stable, reliable power to all connected batteries.

Diode Technology

This component plays a crucial role by allowing current to flow in a single direction, ensuring simultaneous charging while keeping the batteries isolated.

Voltage Compensation

Utilizes a special compensation diode that adjusts the alternator voltage output to maintain optimal charging levels by negating diode-induced voltage drops.

Energize Feature

An integrated built-in energize circuit that triggers the alternator to commence charging, ensuring compatibility and functionality with modern alternators requiring a DC signal.
