I'd have to look to see what the actual threshold is. BUT... 2A is my recollection as well since we have people using these at 12V, and at that low of a voltage the current goes up dramatically.
There are only limited cases where any fuse will blow before the overcurrent protection. It all depends on the speed of the fuse and the current being drawn. -forrest On Sat, Nov 29, 2014 at 4:10 PM, George Skorup (Cyber Broadcasting) via Af < [email protected]> wrote: > Well if you plugged an UBNT radio into the SyncInjector, that will do > it.
