rui deng / riden support is amazing i broke my rd6012 one day by backfeeding it voltage by putting two in series and turning off the wrong one first.. i wrote them on aliexpress and asked them for assistance what went wrong. my fault was, when i turned it off it took forever to go to 0V. within a few hours they sent me a picture of the PCB with components marked i should check, turns out that those parts had died. it was a mosfet and a ptc. they told me the part values/numbers and to replace them. ordered them, repaired it. works like new again. never had such a repair friendly support before. just the schematics they keep as a secret.
At 300 watts, without a cooling fan. Obviously, the efficiency is very good. It would be nice if you can throw in some numbers, just for our references. Thanks Kerry, you are the best!
With these incredible products i could set my electronics lab bench up on my coffee table while watching TV and eating my dinner. Nice review Kerry. I just bought a East Tester ET3360c and I'm very happy with the unit. It's a good time to be into electronics. Love your channel Kerry. The KK6006 might just be what I'm looking for.
I have a RD DPS5005 which I bought about two years ago. Mine is permanently attached to a breadboard, and is powered by on old B&K bench PSU, It has fewer menu options and no USB or BT but it does the job,
I have a DPS3005 and I love it. Powered by 5S 2P 18650s in a 3D printed enclosure, so totally portable. I use it daily. Very tempted to get one of these though, but would still run it off a battery pack as plugging into the mains is not always convenient.
VERY cool. I just got back into electronics, and I also plan on doing a little chemistry, and plasma experiments. I'll either get this or a similar unit. Love the video! 🙂
I love your consistently detailed review! I've seen a lot of handheld oscilloscope reviews from you, and I was wondering if you could review a pocket oscilloscope from dreamsourcelab model DS4T1012? The product says it has 150mHz bandwidth, 1GSa/s, and a whopping16Mpts of storage depth. I have one OWON HDS2202S thanks to your video and it only has 8Kpts of storage depth.
Can I use 3 of this power supply in series to get high DC voltage like 120-140V but all powered from one 48V battery , what should I pay attention to as protection ? Thank you for all educating videos.
Good review, just came over this PSU on aliexpress and i was looking for some review hands on. My question would be .. regarding that overtemperature component.. is it the shunt or the tranzistor/diode/voltage regulator close to it ? I am thinking if is the shunt .. than a swap with a higher power rated one .. would solve this over heating ( or a smaller R .. but this will throw out the ADC readings :-/ ) .
Looks like your scope was saturating on that first current measurement, second one showed the correct value. It is not clear from your ripple measurements if you were measuring or switching noise or ripple, judging from the bandwidth adjustment I think you may have been seeing switching noise, not the ripple. Also, it would be better to measure ripple under load, not open circuit. You did some load measurements where the output noise could be seen but not measured. You talk about the startup response but not transient response, they could be vastly different. All in all the review was a nice introduction but not useful enough to draw any conclusions.
Yep the current clipped on the scope. The voltage limit was 5V so still should have hit 5A without OCP. And agree with loading the supply for ripple etc
Nice review as usual. If I ignore my new rule to not look at anything without USB C connectors, this thing has a terrible interface, it ought to have 1mV/1mA set capability up to 9.999, and it's kind of noisy even if it's well below spec. It's almost OK, but that USB is a show stopper.
How foolish are you? Since this is a buck (stepdown) converter, having a maximum output of under 20V would make it basically useless. You are probably the only person in the world who thinks that USB-C is mandatory for all equipment.
@@KerryWongBlog It would be like with the volts, instead of reaching the selected voltage( for example: 19, at once) it hits, let's say, 4 volts or 7 volts and quickly goes up to 19 volts? Thanks for the info!
x1 probe is cheating, it limits the bandwidth more than 20Mhz!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! LIke all these digital power supplies, the use is CUMBERSOME!
rui deng / riden support is amazing i broke my rd6012 one day by backfeeding it voltage by putting two in series and turning off the wrong one first.. i wrote them on aliexpress and asked them for assistance what went wrong.
my fault was, when i turned it off it took forever to go to 0V.
within a few hours they sent me a picture of the PCB with components marked i should check, turns out that those parts had died. it was a mosfet and a ptc.
they told me the part values/numbers and to replace them.
ordered them, repaired it. works like new again.
never had such a repair friendly support before. just the schematics they keep as a secret.
Привет!

Would've been nice to also see the ripple when slightly loaded, and highly loaded, e.g ~5% and ~60% or something like that
Thanks for testing this, was considering building a PSU and wasn't sure how accurate these were.

Thank you for the review. I just bought this power supply and I am very satisfied with the supply and your guidance.
It’s definitely worth garage work. No problem from me. Great test man. I learned some thing’s from your analysis. Great work.

am vazut multe filme cu acest RK6006 Acesta este cel mai bine explicat..de unde cumparam sensor temperatura?10kntcb3950
22m14s... the scope is CLIPPING. i sadly i dont know if your ripple measurement can be trusted if you do such a obvious mistake...
It only looked like it was clipping because he changed the scale after capture, he done the test again with the correct scale
Hi, would this unit be able to step up the voltage from 12v 9A to 39v 4,4Amps ? That way I could charge my scooter from my solar system.
why does it heat up when idling? I haven't put it in charge yet because I'm afraid of destroying it. I haven't attached the fan and NTC yet

Hi kerry have you tried the xy5008?
Would be nice if you test that one
As rk6006 is not available here (yet)
I already have a DPS-series unit in an enclosure. I wonder if this is the same form factor so I can just switch them over?
Looks like the dimension is the same: 79*43*54 mm
Thanks for test but How is the noise at full charge ?
How about when 5A, ripple voltage?
Hello, if it had a cooler, at what temperature does it start?
Hello, what is the thermistor resistance value?
Why when you turn on the output with no load the amps go up quickly and down again? Are those random peaks normal?
Where did you see that? Could you share a timestamp?
@@KerryWongBlog 5:38 (51 milliamps); 7:04 (97 milliamps)
@@mirrorseyes my guess is that the current readings you saw is the output capacitor being charged up, which is normal.
