I bought a #Hangell (no, I wasn't familiar with that name) switching bench power supply and it arrived. It happens to be one that #BigClive just briefly showed in one of his unbagging videos.
I got it because my existing old #linear supplies max out at around 18 V, and that has been a hindrance of late. A #switching supply isn't ideal, because of the possibility of noise, but this model will do 5 A at 60 VDC, and a linear supply that can do a couple of amps at that voltage is big, heavy, and pricey.
So of course, as soon as I received it, I took it apart. As you do.
And ... I'm pleasantly surprised. The #PCB layouts look good, the assembly appears very good, with proper pick&placed #SMT components and reflow soldering, not hack-job hand soldering. The components seem to be #quality, even name-brand where appropriate. There are what appear to be genuine class X and class Y #safety capacitors everywhere they should be. The front binding posts are fairly typical cheap #Chinesium ones, but appear to be from the better end of the quality spectrum as far as those go.
One ding: the multiple #electrolytic output caps appear to be 63 V-rated ones. For a supply that goes up to 60 V, that's just not acceptable. Maybe that's because this unit can also be had in a 30 V model? Or maybe they're just hoping you don't notice.
I'm sorely tempted to replace them with 100 V-rated ones before I use it. I'm going to add some more output #filtering as well.

Just a brief #factoid to perhaps save other #electronics #hobbyists some time.
#BigClive frequently uses a particular type of crimp-contact-and-housing as a universal socket for LEDs and other leaded components. Not just any such connector will do; various #JST, "#Dupont", and others won't work, because they only grasp pins of one particular size and/or shape. If the lead is too big, it won't go in, and if it's too small, it won't stay in.
If you want to use these connectors - and note you can get the housings with more than 2 contacts, so you can use them for transistors or weirder things too - the magic search term is "KF2510".
The reason these work as universal sockets for leaded components is because the contact is a spring that pushes from only one side of the housing, pressing the inserted contact or lead against the far side of the housing, and therefore provides a friction fit for any size lead (within reason). Most crimp connectors instead have particular shapes for their contacts and will only "grab" something the right size and shape.
