    Convert 0-30V 3A PSU to 5A or more

    Hi again, now I understand the question about the transformer: Without mod.: free: 26,33V loaded circuit with 25V preset/4,3Ohm: 25,7V modded: free: 28,96V loaded: 28,3V I got these values from my records and I could also read the Voltage after the rectifier/smoothing sinks on the big...

    Convert 0-30V 3A PSU to 5A or more

    Hi, I can measure the output disortion, what I did was after my mind to determin the point when the circuit becomes instable or the supply voltage drops too much. When I set the potentiometers beyond this point when driving low resistance loads it shows in form of fast growing spikes on the...

    Convert 0-30V 3A PSU to 5A or more

    Hi, as promised I want to post the fruit(s) of my efforts. Thanks again to everybody in the front lines for developing the circuit to this state. The image quality is very low but its the best I can offer, therefore I have not tried to make an image of the scope line when testing the circuit...

    Convert 0-30V 3A PSU to 5A or more

    Thank you for your fast reply, I have all missing parts together now (mostly high power resistors). Except the OPamps MC34072 was not in stock the other n/a. Ill figure out about this problem later. Tomorrow will be a corrosive day (hopefully). Ill keep you updated (maybe with some pictures...

    Convert 0-30V 3A PSU to 5A or more

    Hi there, I have researched a bit and found this project worth building, it is of usable quality and as a big plus the layout is available so Ill just give it a try. Since I have a 24V/210VA transformer available this is my starting point. I want to use the layout of the original project of...

    Convert 0-30V 3A PSU to 5A or more

    Hi, this is my first post here, so please dont eat or beat me. I WAS willing to build either the oiginal or the improved PSU. I even bought some parts for the project today. But after coming home i made the mistake reading the two threats. The one for the original design with incredible 78...
