And now it’s the turn of the last, sixth power supply made by Mean Well. I decided to save this one for last, partly because its design stands out from the rest, and partly simply because I liked the way it looks. In any case, I found it interesting to take a closer look, and that’s what I’m going to tell you about today.

I only recently posted a review of the Mean Well HDR-60-12 power supply, and today I'm reviewing its larger "sibling". It's very similar, but it also has a few features of its own. Both power supplies share the same form factor and output voltage—though I'm getting ahead of myself. More on that in the review.

Today I'm reviewing another power supply made by Mean Well. This time, it's a model designed for mounting on a DIN rail. I've already reviewed a similar power supply, but that one was intended for industrial use. This time, I'll show you a more "home-friendly" version. Inspection, schematic, tests—as always.

Not long ago, I promised a review explaining how to add digital control to a linear power supply board. Keeping that promise, today I’m posting a review of the board itself, along with some drawings, the schematic, firmware, and, for the real enthusiasts, the source code.

So, today I have the third of six power supplies sent to me by one of my readers. This time, it’s a relatively compact and inexpensive power supply. I’d even say it belongs to the budget range, since in some ways it’s noticeably simpler than the previous ones. But simpler doesn’t always mean worse, and I’ll try to show and explain all of that in this review. Anyway, if you’re interested in branded power supplies, I think you’ll find something new here.

Recently, I published a review of a kit for building an adjustable linear power supply with an output voltage of up to 60 V and current of up to 20 A (at least in theory). Today I’m reviewing a product from the same seller and the same series, but this time it’s not a kit—just a standalone module that can also be used with the control board from the previous kit. But I’ll cover everything in more detail in the review. I’ll also include the schematic for the relay module from the previous review.

Today's review covers a topic that's quite familiar to radio amateurs. There are plenty of reviews of adjustable power supplies, as well as kits for building them. I've posted a couple of similar reviews myself. But today's kit is a little unusual, both in terms of power and circuit design. Of course, radio amateurs have used all these approaches many times before, but this is the first time I've come across them all together in a kit, so that's what I'm going to talk about.

Many of you know how much I enjoy taking a closer look at different power supplies. This time, I have a somewhat unusual power supply on my bench—at least, I haven't tested one like this before. In fact, I don't recall ever seeing a review of this type of power supply, even though it's an interesting design, and I've built similar power supplies myself in the past. I decided to order it purely out of curiosity, thinking it might come in handy. More on that in the review.

So, today I have the second review in a series of reviews of power supplies made by Mean Well. This time I chose an open-frame power supply, i.e. a board without an enclosure. As with the last one, it has its own little “twist,” but you can read all about it in the review, which, as usual, includes tests, oscilloscope traces, and conclusions. All in all, I think anyone interested in good power supplies won’t be disappointed.

Not long ago, I published a review of a high-quality power supply from the well-known company Mean Well. Today it’s the turn of another “test subject.” In this case, I have an industrial model designed for mounting on a DIN rail on my workbench. Let’s take a look, take it apart, and test it—business as usual.

Last year, I reviewed two electronic loads made by Sousim. I successfully put one of them to use, and today it’s the turn of the second, which originally could only be controlled using a computer.

It's been a while since I last picked up a soldering iron. A little while ago, I received a very useful little gadget, and today I plan not only to show it off but also to put it to work on a real project. Warning: lots of photos, which may be a problem for users on expensive data plans.

I mention Mean Well power supplies very often in my reviews, and even more often in the comments. Their products occupy a segment where the price is not exorbitant, but the quality is very high. One of my regular readers sent me this power supply specifically for testing, and I’m very grateful to him for that. He also asked me to put it through its paces, which is exactly what I’ll be doing today. So, if you’re interested in branded but not exactly cheap power supplies, I don’t think you’ll be disappointed.

This is the third and, for now, final review in a series about used power supplies for various DIY projects. Today I’ll tell you how a power supply can sometimes turn out, when tested, to be an “overclocked” version of a simpler PSU. I hope you’ll find this interesting—or at least useful. Tests, schematics, and other nonsense as always after the jump.

As I mentioned in my previous review, I received several different power supplies, and today I’m reviewing the next one. Last time it was a 12 V power supply, but today’s model has a less common output voltage: 48 V. It still has its own area of application, which I’ll discuss at the end of the review. As usual, I’ll cover the tests and circuit diagrams, and answer some of the questions people asked in the comments.

Many readers know how much I enjoy writing reviews of power supplies. As it happens, I recently got my hands on quite a few of these devices. The thing is, not long ago a well-known store started offering a variety of power supplies pulled from equipment, and today I’ll tell you about one of them.

Phones, tablets, smartwatches and fitness trackers, sports watches, e-readers, headsets and speakers, power banks, and plenty more all need a free USB port from time to time. At home, and especially at the office, there often aren't enough outlets to plug in all the chargers you need. I'd been planning to buy a charger with several USB ports for a long time, but never got around to looking through the options. What finally prompted me to buy one was a colleague asking me to help choose a model. Writing this review took quite a while—you'll see why later—and in the meantime, my opinion of the Aukey brand changed dramatically.

Not long ago, I posted a review of an almost no-name charger (power supply) rated for 5 V and a claimed current of 7.2 A. As it turned out, the actual power was considerably lower. Today I have a model from the better-known (or perhaps simply known) brand BlitzWolf on my desk, with a claimed combined output current of up to 10 A. Inspection, teardown, tests—as usual.
