Hello Michau, >> A picture would be nice, especially one where the writing on the >> parts can be read. > > This is best I was able to do, hopefully it's enough :-) > > http://imageshack.us/a/img835/3140/img2104y.jpg That's a very good picture. At you transformer is a part number 324459-02 and the (german) manufacture Zollner (Elektronik AG) in 8491 Zandt. (8491 is the old zip code in Germany from the company.) The power unit from my 610 has an other part number: 324459-01. All the prints on the transformer: (line) 3 P/N 324459-01 4 (brown) EGM Made in W. Germany (nc) 2 1 - 2 220V 50Hz 5 (black) 1 - 3 240V 50Hz 5 - 4 16V 1,9A (line) 1 5 - 6 16V 1,9A 6 (brown) I would try to disconnect the transformer from the pcb. Then put an low voltage (for example 12V) at Pin 1 - 2 and after that try with pin 1 - 3 (or 2 - 3). Now you can messure the voltage at pin 5 - 4 and 5 - 6. If the transformer is an 110V typ the output must be 1,75 V. If it is an 220V/240V typ you must messure under 1V. Only if you use the winding for different voltage of 20V you will messure 15V! The factor between input voltage and output voltage is normaly constant. If the transformer has a short circuit the output voltage will be lower. With the low voltage the current is lower and you have a chance to messure without blewing the fuse. Martin Message was sent through the cbm-hackers mailing listReceived on 2013-03-29 13:00:24
