RD6030 60V 30A power supply feedback
good adjustable power supply, it has cutoff current and cutoff temperature setting for battery charging
RD6018 Screen Broken! and how to replace a new screen

RD6030 actual test: output voltage and current accuracy and load regulation
Voltage load regulation at 5 V not so good
4.86 V instead of 5.00 V at 30 Amps
4.92 V instead of 5.00 V at 10 Amps
for higher voltage itâs better, but still the same drop as with 5 V.
39.92 V instead of 40.00 V at 10 Amps
39.87 V instead of 40.00 V at 30 Amps
so for aplications where accuracy at low voltage is needed not as useful as I thought. This why I always check the voltage with a separate meter, since the voltage shown on the display is not the real voltage which is given of the output.
Why the current is shown as 0.99 A instead of 1.00 A if there is real 1.00 Amp? This is annoying thing also on RD6024 and is even present on higher current settings.
PS: @RD_tech Did you plan a version with 30 V and 60 A current? This would be real no-brainer for me (and you have a USP) since there are no really good PSUs with 60 A max current out there.
Probably because the output voltage sensing isnât as close to the outout posts as it should be, butâŚ
Even if the voltage was dead on 5V at the posts, you would still need to do this considering how much voltage drop there is in wires/connections at 30A.
Ideally such bench PSUs would have remote voltage sensing, so it could regulate the voltage at a specific point in the circuit youâre powering, I already mentionned this in an older RD thread, and IIRC it wasnât considering for future models, which is a shame because this is an excellent feature to have, that is only available on very expensive bench PSUs.
That would be very nice as well, even 50 or 40A.

At least the 6006P can also be switched to external sensing, and then you connect a wire to an internal connector that will serve for the feedback.
The original RD6006P manual does not show this yet (and their pictures have no hardware for it visible). So looks like it was added with a silent revision.
Thatâs great!
But then why wasnât this feature included in the RD6030 @RD_tech ?
I checked product images, looks like 6012P, 6018, 6024 and 6030 can not do that, which is very weird. Only the 6006P. 6030, 6024 and 6018 are mostly the same PCB layout, so seems like the 6030 mainly is an update of an existing platform. Only the 6006P shop listing speaks of the remote sensing - I was pretty sure they all could do it. And even on the 6006P it looks like an afterthought - both the switch to toggle between internal/external and the connector are on the rear of the PCB. Things like these should be on the front panel.

Their choices for product design seems to be weird. I remembered about a discussion about the flashing temperatur indicator on the display (maybe it was in the marketing-thread with all of these 5-star review copies), which also fits into this pattern. They just get in their own way, and feedback doesnât necessarily seem to be taken into account in new product designs now either.
The Drop definitely has to do with wire size and length â Try putting your meter at the end of your wires and adjust voltage from there
I have several of their PS and really donât think those binding post are that great. On my DPS 6020 I added a XT90 connector with 12 gauge wires ( 2" long) , then I use 8 gauge leads that are only about 14". At 20 amps I still get a little drop but minimal
for the remote sampling function, it is tested on RD6006P new hardware, it needs skill,we will consider if other models needs this according to the feedback
yes the output cables will affect the testing, in this video, I use our 36A cable to test, different cable will affect the result, the voltage drop on the cable cannot be avoided, we can only make it smaller
for the remote sampling, it is tested on RD6006P first, according to the feedback we will check if we keep it or make it as software makeup for voltage drop

BTW the noise comes from the the screen backlight PWM dimming around 1.5kHz, once set at 5/5 brightness the noise disappears.
really , did you test ?
Oh, the classic. One of the first eevblog DMMs had the best exact same issue, just that they always buzzed no matter the brightness. Once you turned it off they were silent ^^

High quality products. Good and high-quality delivery, very reliable foam packaging box. As a gift, I received power probes/wires for 36A, (to the first 100 buyers of the Riden RD6030 DC/DC step-down converter).
RD6030 60V 30A power supply feedback
I bought it as a release sale discountShipping came quickly, 36A cable as gift, and I received the packaging in a very safe condition. SellerâŚ!!!Thank you for the gift.
Yes. The screen makes an audible noise at brightness settings of 1-4, but not 0 and not 5.
for this let me check,the default brightness setting is 4, could you please make a video when set the brightness at 4 and 5, see the noise in the video?
