VICTRON battery Isolator Argodiode 100-3AC 100A

The Argofet Isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger), without connecting the batteries together. Discharging the accessory battery for example will not result in also discharging the starter battery.

Argo isolators have a low voltage drop thanks to the use of Schottky diodes: at low current the voltage drop is about 0.3V and at nominal output about 0.45V. However, all models of this type include a compensation diode circuit, which can be used to slightly increase the alternator output to compensate for the voltage drop over the diode.

Argodiode AC models have an additional output for activating the alternator (energize output). This is useful when the alternator needs return voltage/energize signal to start charging.
