Battery distributor 2 120A diode argo 120-2AC - Victron Energy

Description

Diode splitters allow multiple batteries to be charged simultaneously from a single alternator, without connecting these batteries together. During discharge too, the batteries remain isolated, so using the service battery, for example, will not discharge the starter battery.

ARGO splitters have a reduced voltage drop thanks to the use of Schottky diodes: at low current, the loss will be about 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 splitter's voltage loss.

Alternator power supply

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 splitter will prevent any voltage/current feedback 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.
