Max current of vfused for duet 3
-
What is the maximum current that can be drawn from duet 3 vfused?
Can I use it to power two (24V 0.383A) fans and a 24V LED of a pushbutton switch?
Thank you.

@kvi94 Well to be pedantic, the current from vfused is determined by the size of the fuse.
But that's not really what you want to know is it? The answer to your question depends on which connector you use. e.g. Out0 is generally for a bed heater and will take around 15A. Out1to3 are the larger 2 pin JST VH connectors and each of those can take 6A. The smaller 2 pin KK connectors can take around 2.5 Amps each.

Sorry for not being explicit about the particular vfused connector. I was actually referring to the vfused(2 pin KK connectors) which is meant for an always on fan.
If its rated 2.5 Amps, then that should be more than enough for 2 fans and an LED. Correct me if I am wrong.
Thank you.
