Identifying rectifier bridge

[dreamix]

Hi!

Im repairing a 24vdc psu, and need help finding a replacement for this rectifier bridge. WS04 ?

You can use any bridge rectifier of minimum 1.5A 400v, it just has to physically fit on the pcb

Or 4 diodes connected in a bridge, with the same specifications

Ok thanks! Its a Studer 2x24vdc supply, I dont know the problem is yet, it does work but only outputting 2 x 5vdc

I don't recognize WS04 but W04 is a common 1.5A relatively high voltage (400V) bridge rectifier.

You can check the individual diode junctions with a VOM while the power is turned off, and perhaps unsoldered from the circuit.

A common fault for diodes is to fail shorted (melted).

The psu is the one found in studer telephone hybrid, if anyone know where to find schematic

I dug out the schematic and provide it for anyone else in the future.

If anyone can have a look at these 2 pages, what is the rectifier bridges for 15v suppose to be seeing? pin 1(7.5v) pin 2 (7.5v) ?

Idk why but this was used as a 24vdc supply but dc taken from the +15vdc outs
