Victron Argodiode 140-3AC Battery Isolator 140A for 3 Batteries

Victron Argodiode 140-3AC 3 batteries 140A

Battery isolators allow simultaneous charging of multiple batteries from a single power source, without the individual batteries being connected to each other. For example, the service battery can be discharged without simultaneously discharging the starter battery. The use of modern Schottky diodes also keeps the voltage drop low. It is approx. 0.3 V at low currents and approx. 0.45 V at nominal current.

All models in this series are equipped with a compensation diode that slightly increases the alternator's output voltage to compensate for the voltage drop across the Schottky diodes.

Alternator start-up excitation Some alternator types require a DC voltage at the B+ terminal for start-up excitation. On the one hand, there is a direct cable connection between the battery and the alternator. On the other hand, however, the isolation diode prevents current from flowing back, so the alternator does not start. The new 802AC battery isolator has a special current-limited connection for start-up excitation when the alternator is started.
