I wonder if someone have available the circuit diagram of 1746-P1 (Allen Bradley Power Supply).

I'm trying to fix a board and it could be easier with the diagram.

Thanks a lot!!!

I don't have one but switching PSU units are similar in design.
I was fixing few P2 units which have been plugged to 240V
when configured to run on 120V. In all cases all I had to do
is replace the 22 Ohm resistor and surge suppressor which
died to save the rest...
 
Hi. I'm Esteban, from Argentina. I've plugged a 1746-P2 unit to 240V
when configured to run on 120V. The fuse blow but it seems nothing else is damaged. When I’ve figured out there's a bridge to select between 115V and 230V it was too late. I've put the bridge in the 230V, replace the fuse and reconnect, but a 330µF condenser blow out. I've replace the condenser but it blow again when reconnect. Can somebody help me?
