Hi I bought this acopian linear power supply but Im confused as to which is the positive and negative for the AC input, I couldn't find any info of this on their site, I included picture of it below. thanks

ac voltage doesnt have + -.. its clearly marked on the psu.. The first one on the right is ground then the neutral and the third is live..

A.C. L = AC Live
A.C. N = AC Neutral
To my knowledge an AC input doesn't have a positive and negative terminal. Things may have changed though...

My mistake I meant hot and neutral, so L=Live (hot) and N=neutral, that makes sense. thanks
