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.

I've mentioned several times that we're not just trying to find decent power supplies among all the Chinese junk—we also send the factory recommendations for improvements when a power supply has no critical issues and is reasonably priced. So today, most of the models here are ones we received after they were modified to meet our requests.
