I have a switching powersupply, and on the output side they have the following outputs:

PFD
Inhibit -Ve
Inhibit +Ve
-Sense
+Sense
Current Share

What are these? this is a switching powersupply. Do I need these on the outputside?

 

hi

i believe they are use to track current. likewise if am not mistaken inside your SMPU there's a chip maybe LM325N to track negative/positive voltage/current.

 

Whats power Fail? What does it do? What can I do to use it?

 

hello

is your power supply similar to this?

 

I have a new power supply now. It has power fail and I get a high (5V) off of it.

No its not.

Oh, Happy 1k
