Diode bridge Victron Argodiode 140-3AC – 3 batteries140A – ARG140301020R

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 low 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. For best results, see our ARGO FET diode bridges without voltage drop.

See our free book «Energy Without Limits or ask a specialist for advice on the installation of a diode bridge. Voltage losses caused by the use of diode bridges can reduce battery performance due to incomplete charging.

Alternator power 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 a FET separator is inserted, any voltage/current return from the batteries to the B+ output will be prevented, and the alternator will not be able to charge.
alternator will not activate.
The new «AC» diode jumpers have a special current limiting input that will feed the B+ output when the motor start/stop switch is closed.
