RuiDeng RD6030 Converter Announcement

Quite unexpectedly, RuiDeng has released a new converter model. I really wasn’t expecting this from them after the RD6024 came out. Here’s a quick look at what they’re offering.

A reminder: to keep up with new posts on the blog, I recommend following me on Instagram. I’ll post notifications about all new articles there, and might also write about something interesting from time to time: link to my account

First, this model is currently on sale. As a reminder, this company has a habit of cutting prices right when a product launches, rather than some time later. It appeared on AliExpress literally today.
Second, the discount is available from May 8 to 12, and the converter costs $84.99 and $88.99 for the standard and WiFi versions, respectively. After the 12th, the price is expected to return to the regular $113 and $118.
And third, I’ve already ordered one for myself. At the moment, I can see that 19 other people have ordered it too.

I’ve just noticed that it’s been a year since the RK6006 came out, which I also find quite interesting.


This model is billed as “High current,” which makes sense: 1800 W is a lot. But in reality, it will probably be rated for 61 V at 30.1 A rather than 60 V at 30 A, giving an output of 1836 W.
In terms of the resolution for setting and measuring current and voltage, this model is essentially identical to the RD6024, which I’ve already reviewed. The only change here is that the current has increased from 24 to 30 A. Judging by the trend, the next one should be rated for 36 A. I certainly wouldn’t say no to that :)


Here are the key points from the company’s announcement:
Key features of the RD6030 include:
Support for 60V 30A output (1800W max)
Low ripple: 50mV@15A, 90mV@30A VPP
High efficiency: >95% at full output
Support multiple display styles and custom color
Support PC software control with USB cable connection
Support Phone APP control via WiFi(needs to order the RD6030-W version)

As far as I know, there aren’t any reviews of this model yet, but you can still find some information on the product page, since it has plenty of pictures.
1. The terminals are said to be made of copper, but if I remember correctly, the 6024 had the same ones—or at least they looked identical.
2. The current and voltage setting resolution is the same as on the 6024: 0.01 V and 0.01 A. That’s more than enough for me.
3. The claimed efficiency at 6 V 15 A and 30 V 15 A is 98% and 96%, respectively. Nothing particularly unusual, and it needs to be verified. I’d also like to see measurements at other operating points.


I’ve mentioned the RD6024 several times already, so it’s probably worth including a comparison table of all the converter models, including the new 6030. By the way, I’ve reviewed all the models listed here (except the 6030, of course), so if you’re not familiar with the RD60xx series, I recommend checking them out.


1. The voltage regulation is claimed to be highly accurate, but to be fair, the previous models were already excellent in this respect. The main thing is that they haven’t made it worse, which is good news.
2. There’s input overvoltage protection, and it’s also claimed to withstand up to 100 V at the input for short periods. I don’t remember seeing that before.
3. They also claim there’s no overshoot when the output is enabled, but that was true of all the previous models too. They may simply have added a delayed startup, though; we’ll have to compare them.


There’s software for PCs and mobile devices, though I didn’t quite understand what they mean by “RD6030 only.” What I like even less is that the controls are locked again when it’s connected. That’s inconvenient.


The internals look very similar to the RD6024, except the power components are a bit beefier and there are more capacitors, which makes sense.
They’ve also switched to a different type of fuse, slightly longer and rated for 40 A instead of 30 A.


So I can already anticipate a few questions.
First, what should you use to power this thing? For now, the manufacturer recommends a 1500 W power supply, which I reviewed not long ago. You can use a different one, but to get the full output voltage, you’ll need a power supply rated for 65–68 V.
Second, where are you going to fit all this? It's a little simpler here; they recommend their S800 case.


Third, I was concerned about the cables, since theirs are rated for only 25 A. I was disappointed to find that after buying two sets of these cables, it turned out they offer 36 A cables! By the way, this indirectly suggests that we can expect an RD6036 model.


When I first saw these cables, I wondered how they planned to use banana plugs at that current, but the answer turned out to be simpler: they don't use banana plugs at all. The cable has an 11 AWG cross-section, roughly 4 mm² or more, and is covered in extra-soft silicone insulation.


The alligator clips are beefier now too, but I have to say that while I like the 25 A cable itself, the clips are a bit too stiff.


For now, this is of course only indirect information, but knowing this company, we can expect the model to be almost identical to the 6024 and its predecessors. Of course, I can't say it's perfect and that everything is just great, but to be fair, before releasing a product they do try to get it into a reasonably good and reliable state. The only thing I didn't like about the 6024 was the quality of the fan they used; it started buzzing after about 50 hours of operation.

To answer the question of whether to buy it: personally, if these specs work for you, then yes. There are basically no alternatives (almost none—the one available has awkward controls).

And once again, I'd like to appeal to RuiDeng: let's work together to develop an electronic load based on your converter (case, interface, analog and digital sections). I'm fed up with Atorch loads; I want a good, properly designed, affordable electronic load—even without the power module, or at least without the heatsinks!!!!!

That's all for now. Let's wait and see what arrives. It's a shame the price will have changed by then, so it's better to decide now.
