Double check the spec sheets please.. there are a couple of models which are showing to provide 2A on the 24HV & 48HV ports, most of the others are showing to be rated for 1.5A.
In my experience Chris S. is a stickler, expect exactly what is listed, nothing more nothing less :) https://www.netonix.com/media/wysiwyg/ws-specsheet.pdf (FWIW, I never noticed the Amp ratting on the POE out on the different netonix models until your email) :) Regards.
