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.

No, I didn't solder a very clearly marked polarized electrolytic capacitor backwards across the power rails of my project board tonight, causing it to smell funny, emit a loud POP, and spit its guts across the room.
Not that you can prove, anyway.

The relays arrived today. I'm going to replace the 2 #electrolytic #reservoir #capactiors on the board as well - spending 17 years 20cm from a giant gas burner probably hasn't done them any favours. But those didn't arrive. I can't even tell if they've shipped.
Coda: got the #FedEx bill for tax & #customs clearance/#brokerage fees on the first motor today. $111.
Wanna bet northamericahvac.com didn't do the #paperwork on the 2nd motor right, and I get another #bill for that one?
