This little 12V DC power supply is easy to build with few components and has a nice plexy case that holds everything. Nice is also the included transformer so you can power it with 220V AC. Only minor point of critic is that the screws for the standoffs to mount the circuit board into the case are a little bit too long and can't be tightened enough. Fortunately I had some shorter screws lying around. The output voltage is quite accurate. All by all good value for money :-)
It was a little fun to assemble the kit it came without any instructions but that wasn't a problem for me. It didn't came with all the screw needed but also not a problem because i had some laying around. The power cable has only 30cm so it's too short. I will replace it for a longer one. The acrylic case could be stronger the plates are too thin. Overall it's a good kit for the price it costs and kept me occupied for a few time.
ürün güzel tüm parçalar tamam sadece dijital VoLTmetre çalışmadı.
There is some minor damages on pcb. But not big issue.
let's see if it works...
All items arrived within the shipping time. Just have to solder the components as soon as the soldering wire arrives. Many components are different from what is in the pictures, but I guess that doesn't matter much. My only question is... what is the switch for? Is it even used in this module?
Nice project to learn a little more about electronics. Download the drawing from the internet. lots of fun. package arrived well within a reasonable time. Have fun
Fast shippng item is almost complete....no manual
acryl housing has some error. ex ) switch is smaller than the hole and power cord is not fit in the hole so user can contect high voltage 220v directly.
perfect!!!!!!!!!!!!
