power supply How to measure the capabilities of a wall adapter


Posted on Feb 7, 2014

The device exhibits 24V at no load on pins +4, 5 and -7, 8. According to Wikipedia, this is called a passive power injector. I tried drawing 1A from the device and failed (some protection drops the voltage to 0V). @W5VO, thank you for your care of the question. However, protecting it removed the answer of a new user, user2020 I believe, that contai
