We’ve reached the last compact adjustable converter in the RK series. I have to say, Riden has pleasantly surprised me with this lineup: it covers a wide range of power and current ratings, includes an H-series model—a less powerful counterpart to the RD6012H—and also a model with an extended output range, which is what I’ll be looking at today.

I've taken a look at another converter from Riden: the RK6018, which is advertised as delivering a full kilowatt of power. And yes, I think that's a record for something this size so far. Let's take a closer look and put it to the test.

Riden is really on a roll. I’d just finished reviewing their new RK6012 when they released three new models at once. I already have two of them at home, and the third is on its way. Honestly, I never expected them to bring so many new converters to market so quickly. Though, to be fair, I wouldn’t mind seeing an RD6036, first of all, and an electronic load from them as well.

I’ve already posted an unboxing video of the RD6030-max power supply, and said then that I’d write a short article about it too. But one thing led to another, and the article kept getting put off. I’ve finally found the time to pull everything together and tell you about it.

A while ago, AliExpress started showing me listings for the same power supply from different sellers. I had a project that called for exactly this kind of power supply, so I first bought a few to try out, then some more, and then more again. Before long, I was using these power supplies in production devices.

Not long ago, I wrote that I’d ordered Atorch’s new BW600 electronic load. I’ve now received and tested it, and have also figured out some of the new version’s quirks. I found both advantages and drawbacks, and built a couple of new devices based on this controller.

One of my readers saw my comment about the low-voltage UPS board and suggested I review it, so he sent me this board. Given the current circumstances, these devices have become relevant again, so of course I agreed—especially since I was very interested in it myself.

A couple of weeks ago, I contacted a Riden manager about a device. Things turned out to be a little more complicated with that one, although it’s already on its way to me. But he immediately offered me their new model to review, and I couldn’t say no, since I’ve reviewed pretty much all of their devices.

About a year ago, I reviewed my Atorch load switching board. Then they released a new version of the load, followed later by a new switching board. I waited a long time, hoping someone would post decent photos for analysis, but nobody did, so I finally bought one at the end of last year.

Some time ago, I was asked to review an LCR meter from Fnirsi. I can’t say it was convenient for me, since my workload is very heavy, but in this case curiosity won out—especially since I’ve been using a similar instrument for quite a while and know that a lot of people bought one after reading my review. And as far as I can tell, the Fnirsi LC1020E has already been reviewed by quite a few authors, so my review will mostly just be an addition to what’s already out there.

Last fall, I had a small order lined up to build a clever UPS, but the order was eventually canceled. The power supply I’d bought for it, though, was still here. I finally found a little time to test it, and I think this will be useful for anyone planning to buy one like it.

Not long ago, I noticed that the range of converters from the well-known company Ruideng had expanded with a rather unusual model. Naturally, I contacted the manager and ordered one for review. To get ahead of myself, I’ll say that I haven’t regretted deciding to test this model for a moment.

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.

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.

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.

Back in the spring, I bought a pair of tweezers on sale (three items for next to nothing), tried them out, and ended up tossing them in my desk drawer. Now I’ve finally found a little time to tell you what they’re like, why I don’t use them, and how they compare with my main pair of tweezers, which I bought quite a while ago.

Not long ago, I spotted a new product from Atorch, got interested, contacted the manager, negotiated a discount (unfortunately, not a very big one), ordered it for review, received it, and now I’m sharing it with you.

A quick look at a handy little gadget. I bought a few to have on hand, and maybe I’ll include one with one of the new loads.
