Victron Argodiode 140-3AC 140A 3 battery isolation diode
With the help of battery isolator diodes, two or even three separate battery circuits can be charged from a single power source. The batteries do not need to be connected to each other, which greatly simplifies the installation of these isolator diodes and even saves installation costs.
Technical features of the Victron Argo 140-3AC battery isolator diode
- The Argo series uses state-of-the-art Schottky diodes to keep voltage loss as low as possible.
- Features a current-limiting connection for starting the generator (e.g., alternator, generator).
- The Argo 140-3AC model delivers a maximum charging current of 140A and can serve 3 separate batteries or battery banks
- The maximum current of the alternator is also 140A. This means, for example, that the vehicle battery can be charged without simultaneously discharging the starter battery.
Minimal voltage loss thanks to the latest Schottky diodes
The use of modern Shottky diodes also keeps voltage loss to a minimum. It is approx. 0.3 V at low currents and approx. 0.45 V at rated current. All models in the Victron Argo series are equipped with a compensation diode, which slightly increases the output voltage of the alternator to compensate for the voltage loss caused by the Schottky diodes. This is important because if the isolating diode is connected to the wiring between the alternator and the battery without further measures, a voltage loss occurs, leading to incomplete charging and premature aging of the battery.
Current flow regulating alternator connection
Some types of generators require a DC voltage at the B+ pole for start-up excitation. On the one hand, there is a direct cable connection between the battery and the generator. On the other hand, however, the isolating diode prevents the current from flowing back, so that the generator does not start up. The Argo Diode from model 80-2AC onwards has a special connection for start-up excitation when the generator is started and ensures a smooth flow of current between the generator and the battery.
