Argo Battery Disconnect Diodes 80-2SC

Battery disconnect diodes allow for the simultaneous charging of multiple batteries from a single power source without connecting the individual batteries together. For example, the onboard network battery can be loaded without simultaneously discharging the starter battery. By utilizing modern Schottky diodes, the voltage loss is kept low, approximately 0.3 V at low currents and around 0.45 V at rated current.

All models in this series are equipped with a compensation diode that slightly increases the output voltage of the alternator to compensate for the voltage loss caused by the Schottky diodes.

If the disconnect diode is connected directly into the wiring between the alternator and the battery without additional measures, a voltage loss occurs, leading to incomplete charging and premature aging of the battery. Some types of generators require a DC voltage at the B+ terminal for starting excitation. The connection between the battery and the generator creates a direct cable connection, while the disconnect diode prevents current backflow, which can prevent the generator from starting.

The new 802AC battery disconnect diode features a special current-limited connection for starting excitation when the generator is started.
