Yesterday gave in forum pictures from one computer PSU. It has no labels on it, it came that way before a lot of time./gift from friend/
I have 4 diodes close to the pulse transformer and wanted to check them. I see only "48" on them. They are coloured red/black and are small.
I have readings from about 0.590V with black probe to black line of the diode and reversed OL.

Can i at all transform that 48 sign to something meaning or without pdf i cannot do anything.?

:)

Hi,
Those 4 diodes configure as bridge rectifier. The no 48 is the last digit of lets say 1N4148.
Since a small diameter cannot write it a complete label.
