Request info on 12/48v PSU

$begingroup$


I've got a power supply unit from a defunct/decommissioned Satellite Internet setup, and I'm hoping to get clarification on some of the markings on the label.



In the following picture, there's four pin numbers, followed underneath of pins 1 and 2 both volts and max amps, and pins 3 and 4 simply "RETURN".



My question is whether I'm reading the label correctly. (Technically, I've got a few questions here).



Does max(A) under pin 1 mean that at 12v I've got 2.99A available, and at the 48v pin, I've got a max of 0.82A?



Also, when pins 3 and 4 are reflected as return, I'm assuming that means ground, yes?



I'll summarize my questions here to consolidate:



1) is pin 1 +12v @ 2.99A?



2) is pin 2 +48v @ 0.82A?



3) are pins 3 and 4 ground pins, that could (and potentially should) be wired together if both pin 1 and 2 are in use simultaneously?



Here's the pic of the label of the power supply in question:

    @K.S. I thought so. It appears obvious, but I thought I'd ask the experts.

Yes, your interpretation of the label is correct as far as I can tell.



Note also that $12 mathrm{V}·2.99 mathrm{A} + 48 mathrm{V}·0.82 mathrm{A} = 75.24 mathrm{W}$, in agreement with the 75 W power rating. This, combined with how simple this interpretation of the markings is, is sufficient evidence for me to say with confidence that you are correct.
