Battery distributor 2 80A diode argo 80-2AC - Victron Energy

Description

Diode distributors allow multiple batteries to be charged simultaneously from a single alternator, without connecting these batteries to each other. When discharging, the batteries also remain isolated, so using the service battery, for example, will not discharge the starter battery.

ARGO distributors 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 power, 0.45 V. All models are equipped with a compensation diode that slightly raises the alternator's output voltage to compensate for the distributor's voltage loss.

Alternator power input

Some alternators require a DC voltage on the B+ terminal output to start charging. Obviously, there will be DC when the alternator is connected directly to the battery. However, inserting a FET or Diode distributor will prevent any return of voltage/current from the batteries to the B+ terminal, and the alternator will not start.

The new "AC" diode isolators have a special current-limited power input that will supply the B+ terminal when the engine Start/Stop switch is off.
