3-battery distributor 140A with Argo diode 140-3AC - Victron Energy

Description

Diode splitters allow multiple batteries to be charged simultaneously from a single alternator, without connecting these batteries to each other. During discharge too, the batteries remain isolated, the use of 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 output voltage to compensate for the splitter's voltage loss.
For best results, see our ARGO FET splitters with no voltage drop.

Consult our free book "Unlimited Energy" or ask a specialist for advice on installing a diode charge splitter. Voltage drops caused by the use of charge splitters can degrade battery performance due to incomplete charging.

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 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.
