Hi I bought this acopian linear power supply but Im confused as to which is the positive and negative for the AC input, I coulnt find any info of this on their site, I included picture of it below. thanks
An externally hosted image should be here but it was not working when we last tested it.
It doesn't really matter, as soon as you plug in the plug turned around 180 degrees, you'll be off again. If you really want to do this, then take a screwdriver with a neon lamp inside (dunno what they'Re called in English) and test the socket. The wire that makes the lamp glow is L, the one that doesn't is N IIRC.

Hi,
N= Neutral
L= Phase
This is ac input.
what is the input voltage? (I think 110VAC)
DC voltage out? current output?
Regards

so L=Live (hot) and N=neutral that makes sense lol. So if I were to put neutral in the L input and the hot in the N input what would happen? I imagine the fuse would just blow, not that I'm going to do it but I think it would be good to know.
Mooly I definitely wont forget to connect the ground .

Hi,
Not exist a psu with dedicate one pole at "L" or "N".
some industrial power supply dedicate line pole.(only for legislation)
not blow fuse if you connect this.
both lines input have necessary ISO to GND(ground)

It would work just the same if you swapped the L and N, however reversed polarity can be dangerous (on anything) for anyone working internally on the equipment.
Think about a table lamp with a single pole switch... if you reverse the polarity the lamp socket is always live, even though the lamp appears to function normally.
L = LINE (aka "Hot")
N = NEUTRAL
In the USA at least, LINE/Hot is the smaller of the two prongs on polarized AC wall plugs.
They wouldn't specify which was which if it didn't matter. Even if it only matters for legal purposes, there is possibly a good reason for it. So it's safer to not ignore it.

They are outputs plus and minus, with the option of remote load sensing, then the AC inputs and a ground terminal.
