I have built a project of a insulated Power Supply 230V AC followed by a Variac.
I would add a circuit to obtain DC output.
The voltmeter I bought has only 3 poles: one + = power supply, one = to test the voltage and common negative.
Could I connect all as I show in the schematic attached...
Thanks for the suggestion, but I already tried to order one power supply from U.S. with the same model code, but I realized it was 100-120 V as primary that it is suitable here (220V). Yes.. I can write to ask, but I would try to repair this one, at this point.
I watched very "deeply" using a microscope, because it was my idea too, but it is a 2. Maybe it will be necessary to draw all the schematic of High Voltage section, but it will take me some time. I will try...
I don't suspect the diode..., it is shorted besides other components. I tried to find the schematic of this DSA-0151A-05, but no success... About repurposing another power supply I had thought about, but at this point that I susbstituted all the broken components (except the diode!) it is just a...
I am repairing a 220VAC/5VDC power supply for a router. I am looking for to identify a through-hole diode with marking code 2 18 (printed in two rows: first row 2, second row 18) that I marked with a ? on the photo attached. On this photo you can see the diode at the upper left corner and the...
