just back from holiday and found my cctv has gone wrong.
I need some advice on testing a transformer/power supply. The label on the back calls it a switching adaptor. model FJ-SW4802000F
240v input. The output should be 48v DC, 2000mA.
should I get a fixed AC voltage reading? I think not but I do.

thank you
