BCD 402 2 batteries 40A (combiner diode)

Argo battery combining schotty diode (low volt drop). Twin input single output 40 amp rated. This unit allows for the use of two DC sources to provide a redundant supply to a critical load. (BCD000402000).

Argo Diode Battery Combiners

Diode battery combiners are used to guarantee continuous DC power to mission critical equipment, such as an electronic engine control system. With a diode battery combiner two or more DC power sources can be used in parallel to supply the mission critical load. Failure of one source will not interrupt power to the critical load.
