Do you think the AC inputs connection on Board to the Pin of the Plug was wrong?

QUOTE(blindmutedeaf @ Mar 23 2023, 11:15 AM) AC is ok, they don't quite care. Wow... Appreciate your helpful information! 🤩So after measuring at the output, doesn't have 24Vdc? just happen lately or since day1? For AC --> DC converter normally rectifier gg this is the typical sch (ignore the values) https://www.circuits-diy.com/wp-content/upl...m-Schematic.png  It was working perfectly in the pass 2 weeks. And just go south yesterday 😭 I did test the 24v output via multimeter, either no value or not a stable value. So I tried on my 5v charger , it's stable at 5v+-. That means multimeter is good. You are E&E Expert! I saw an info mentioned about that this kind of power adapter mostly caused by Rectifier! But I don't really have no knowledge about that , in fact I wish to learn 🤩 Do you kind to lead me? |

QUOTE(eddievh @ Mar 28 2023, 12:52 PM) Whats your load power rating in watts? The above power supply only 0.6A. The 1st post one is 5A Ya lo! I think 150W.How to calculate? In this case, the device might not be able to turn on with 0.6A power adapter, right? |

QUOTE(eddievh @ Mar 28 2023, 03:22 PM) W/v= ampere. . This 0.6a definitely not enough. I see! Gain knowledge 😁150w/24v = 6.25A ,am I correct? In fact, the original power adapter only 5A, enough? |
