LS-300W-24V power supply: looks good, I like it
19-09-2025, 03:18
Not long ago, I reviewed an entire series of LS power supplies. They differed slightly in their circuitry and specifications, and some of them were high-power models. It turned out that I’d forgotten to test one model, which was a shame, because it proved to be very good indeed. So here I am filling that gap.

I actually reviewed an entire series of these power supplies, but this particular one got held up in transit somehow, so I’m only publishing its test results now. And believe me, this SMPS is worth showing you.
Four more power supplies: 60, 100, 200 and 400 watts, 24 volts

This is a continuation of the previous review, but this time there are twice as many power supplies, and their voltage is also twice as high. The basic idea is much the same, though: these are very interesting models, and they’re available in Ukraine.

Another batch of power supplies has arrived—lots of them, all kinds—and today I’ll tell you about a couple of interesting models worth a closer look.
Riden RD6018P Hybrid Adjustable Converter

The new Riden product has finally arrived: the RD6018P, a new version of its adjustable hybrid converter. The previous model came out just over a year ago, and that was the RD6030. To be fair, for some reason I thought the next one would be the RD6036, but the manufacturer managed to surprise us by making the next hybrid model an 18 A unit.
Small FNIRSI DSO510 Oscilloscope + Generator

I was sent this little oscilloscope, and in my opinion it turned out not to be nearly as bad as I initially thought. But of course, you can get a better idea by reading the review.

While I’m waiting for my new electronic load, I decided to put together a quick review of another power supply. There’s nothing particularly new about it, but it may still be interesting in some ways—at least because I haven’t had one like this before.
Discount on the popular DL24MP load, plus an update

I have two bits of news today. The first is good: the price of my favorite version of the load has been reduced for the sale. The second—well, I hope it’s good too :)

Today, this is less a review and more a demonstration of how Chinese manufacturers can build two very different power supplies on essentially the same platform.

Once again, power supplies from a Chinese factory have arrived for testing. As you may remember, these tests are aimed either at finding models that offer the best balance of quality and price, or at testing products and getting factory-level issues fixed. I want something simple: power supplies with a decent level of quality that are still affordable.

A couple more power supplies, quite attractive and relatively well made, at least on the outside, but with typical Chinese "quirks" in exaggerated form—at least one of them has them.

You can never have too many power supplies. That’s what I thought, too, so today I’m taking a quick look at four compact sealed power supplies, plus a bonus fifth one. It’s not exactly compact, but it is sealed. And that’s not the end of the bonuses—look for more near the end of the article :)

These are the last power supplies in this form factor to come my way for testing—for now, at least. I doubt they’ll be the last in the long run. They left me with mixed feelings: not bad, but with a few “caveats.” As always, more details in the review.

Another installment in my series of reviews of various power supplies. This time, I’m looking at boards from sealed power supplies rated at 60, 100, 150, 200 and 300 W. I think you’ll find it interesting.

Another installment in the power supply review series, and once again it’s a classic: switching power supplies built around the seemingly eternal TL494 and its equivalents.

A few more power supplies, but this time they’re as classic as they come, both in terms of circuit design and construction, and in how budget-friendly they are. Still, I hope you’ll find this useful.

It just so happened that a number of different power supplies ended up on my operating table. And as you can imagine, they didn’t get there for no reason. Since I have a reason, why not take a look at what they’re all about?
Fnirsi DMC-100 Clamp Meter
27-03-2025, 04:12
As part of a promotional campaign, Fnirsi recently offered me a chance to review one of two devices, letting me choose between a measuring tweezer and a clamp meter. As it happens, the clamp meter caught my interest both in its own right and for a very practical use I had in mind. So today, I’m reviewing the DMC-100 clamp meter.
