I'm going to try a pair of these from Amazon and wanted to know if anyone has any experience with them. Here's a link to the amp kit on Amazon:
Amazon "Jolooyo" JLH amp kit
The pile of Chinese parts is branded as "Jolooyo". The output transistors have "K D1047" on them (see picture). The Amazon listing says that the boards require 24V, but there's no amperage spec shown. I also don't see any way to adjust the current (like trimpots) on the circuit board.
Would a Mean Well LRS-100-24 power supply fry these amp boards?
The Mean Well specs show output as 24V 0-4.5amps (spec sheet below). When I see "0 - 4.5A", I assume the amp boards aren't going to be fed the full 4.5A, right?
Thanks (again) for any help...

The power supply provides current as demanded by the load, up to its current limit of 4.5A.
Note that this kit got bad reviews, so you may want to look elsewhere.

Thanks for the information, Rayma. I was thinking that was the case, but my understanding is limited.
I was drawn to the kit based on the price for a pair of boards. There's a guy on YouTube that has "reviewed" the kit and it didn't seem too awful. I assume that any amp kit based on Chinese knock-off parts is always a crap shoot...
If you're curious, here's a link to the video on YouTube - please let me know your opinion on this if you watch it. Thanks again for your help.
