May be useful if you have a problem with this type 5L0565 psu. I've made a voltage overview from the safe side of the power supply unit, but not from the hot zone because the voltages of the hot zone are comparable to the 25X10 PSU. Nevertheless most of the problems arises on this side, and the measurements could also give a impression if it is a problem on the hot side. For convenience, I also give most data sheets related to this type psu. These are the, IC400 FP5001 U1 MP1484EN IC500 FP5001 U2 MP1484EN Q200-Q001-Q501-Q401 Y1 Q3 5L0565R Q400 FQP 27P06 Q500 FQP 27P06 D300-D301 MBRF10100CT ICI VIPer22A 4AYL5L Be careful with the measurements, do not make any short circuit during measurement. And avoid the high voltage area. Good luck!. Click on the image for a fully view.
