VICTRON ENERGY Argodiode 100-3Ac 3 Batteries 100A Isolator

Diode bridges allow different batteries to be charged simultaneously from a single alternator, without connecting the batteries together.

Even when discharged, the batteries remain isolated, so that the use of the service battery, for example, cannot discharge the starter battery.

ARGO diode bridges have a reduced voltage drop thanks to the use of Schottky diodes:

at low current, the loss will be approximately 0.3 V, and at full output, 0.45 V.

All models are equipped with a compensation diode which allows the alternator output voltage to be slightly increased to compensate for the voltage loss of the diode bridge.

Alternator power supply input.

Some alternators require a DC voltage at the B+ output to start charging.

Obviously, DC will be present when the alternator is connected directly to the battery.

However, if a diode bridge or FET separator is inserted, any voltage/current return from the batteries to the B+ output will be prevented, and the alternator will not be activated.

The new ´´AC´´ diode jumpers have a special current limiting input that will feed the B+ output when the engine start/stop switch is closed.
