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:

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.
