I have a fax power suply wich seems to have burned out.
first, there is the transistor, as 2SK727. the resitance between pins is 0.1 ohm between the outer most pins of the case, and about 16 ohm between each of those and the center pin.
i don't think this is righ, or is it? i mesured the transistor outside of the circuit(removed it)
also, there are some leaking filter caps wich i will replace, 1000uF/35V, two of them, and another 1000uF/16V.
the suply comes from a Schneider SPF 402 fax.
does anyone know the voltages it should output? and can i use it for something.
i think it outputs 24V and 5V for sure. the steppers are 24V, though there is something strange about them. on one of them says 'made in japan' and on the other is says 'made in china'. the both look identical and have the same characteristics.
i will attach the picture of the suply. maybe someone can help me with the schematic for it?
thanks!
