I removed later
I had no idea if the Mean Well powersupply has overvoltage protection but just to be shure I add a Pelikan Maxivolt over/undervoltage protection module. After all this is not needed since this PS has overvoltage protection. I removed the Maxivolt module to simplify and reduce weight. I have not searched for best price but I guess you can get these mean well power supply modules for less. The ABS box was even more expensive I guess that can be bought cheaper as well. In case you'll think this thing will make QRM like some other cheap chinese made switched power supplies, this PS is equipped with a EMI filter and to be shure I add a ferrite ring in the mains power cord as well inside the box I cannot hear any noise on my FT-817 coming from the supply at all.
I tested the supply first on my small W5OLF WSPR transmitter for a few days. Now it is ready I test it with my FT-817 on 1W WSPR. So far the supply does a good job and seems to be reliable.
