Yet another dummy loadâ„¢

This time made for the specific purpose of selecting the least crappy USB cables or USB chargers from those lying around that accumulated over the years.

0..2A adjustable constant current.

Edison:
Hello, I haven't been here for a long time and I completely forgot about the request to create a thread with my creations, so at least add something here - the latest work is an AC regulated power supply 30V15A
Some photo of the gauges adjustment, done and here it rests with other creations

Nice day 🙂 Tom

Beautiful.
Will you be willing to share the schematics? :)
Edison:
I will also add one piece of quadruple voltmeter +/- 200V DC, the gauges are galvanically isolated and can thus be connected anywhere in the device under test, I haven't removed the protective film yet, because I don't have the anchor ready - so I don't scratch it.
I still have enough in stock, so I'll throw in something sometimes 🙂
Edison:
Hi, there is nothing complicated about it, a regulation transformer is used at the input and a large toroid at the output - I needed another AC source and so I quickly built it from what I had at home, I originally thought about regulating the current, but in the end I didn't do it.
