The slow LCD display settling time is an artifact of the "Measure" option which slows the display by averaging it. I was confused at first too. Change Measure to 'High' and it will update faster. Still slow to turn off which is expected as the caps drain.

[@grooyo]

The PSU have batt. charging capabilities, and temperature sensor is for monitoring batt. temperature and protect battery from overheating.

[@ericbraithwaite8497]

There is a problem with these units when set to current limit - and it can be a killer. The current limiting function only comes into effect after the (quite large) output capacitors have discharged. I could't see from the video how big those 3 capacitors are but I guess they are reasonably large. Set the output to 60v at 10mA and then short it out and see what happens. All that charge has to go somewhere. This is not a criticism of this particular unit, I think all of them work the same way. Othere than that it looks a nicely built unit and the keypad for data entry is a welcome addition.

[@jeffescortlx]

I think if the output-on button is used, instead of physicality disconnecting the leads it avoids the capacitor discharge issues with current dumping.

[@ericbraithwaite8497]

@@jeffescortlx You are quite correct jeff, using the on/off button allows a safe start, The problem occurs when the connection to the load is opened and closed again while the PSU in in the 'On' state. Users should be aware that under these conditions the current limit only works after the capacitors have discharged sufficiently to bring the voltage down to the current limit level. I lost an expensive LED chip this way. One learns.

Ordered this on Nov 10th, they still haven't shipped it. I was planning to compare this to the Gopher NPS1601 which has superb performance and is actually cheaper.

[@sdgelectronics]

It went out of stock for a while when I looked a few weeks ago. Looks like the manufacturer are having trouble keeping up

[@kioanakos]

I am really interested on that comparison. I have ordered the Gopher PSU 10 days ago (still not shipped) and I hope I will not regret it after the results of your comparison 😐

[@Conservator.]

VoltLog you made a video on the NPS1601. It might be cheaper but it has less specs and less features. Nps1601 is a 32V 5A power supply while the RD 6006 is 60V 6A power supply Furthermore does the RD 6006 have presets and it programmable. It has an USB port for data logging and a display that can show a graph.

[@voltlog]

@@Conservator. Sure the RD6006 is packed with features there is no doubt about it and you'll see my opinion on that in an upcoming video 😁

[@power-max]

7:20 200mV error at 3A seems kinda significant. They probably made the rookie mistake of sensing voltage before the current sense resistor. 47 to 50 mOhms perhaps?

[@jaro6985]

There are the two 30mR on the negative line, which would be 15mR. Then add the 10A nano 2 fuse on the positive lead, ~10mR plus omni blok holder resistance (can't find a rating for this). So thats starting to get very close to the calculated 60mR. Very disappointing if they are measuring the voltage prior to the fuse.. would be fine on a smaller supply but this thing is 6A.

[@jan.tichavsky]

@@jaro6985 Fuse, really? Even 70s power supply already had electronic fuses there (within 723 regulator), they must not be confident in the design that it could blow somehow. I also expected more modern design than something from ATX PC supply. The MDP-XP is much nicer, the output is very low ripple and also it's quite efficient and better design (more pricey too).

[@jaro6985]

[@fschinagl]

@@jaro6985 You can see in the video that the voltmeter (Fluke 289 on the left) is not connected to the output terminals of the PSU but somewhere else - it's picking up voltage drop somewhere down along the leads.

[@movax20h]

The big output capacitors are a bit worrying. But then you had no load at all, so that might be ok. But big capacitors will interfere with ability to limit the current well.

[@Eric-uf8zx]

Nice review, thanks. If you do a followup it would be great to see how it performs under load, like can it deliver the advertised power continuously without melting down, also what does the ripple and switching noise look like at various loads. And a quick look at the dynamic performance would also be great, e.g. in constant voltage mode going from 100mA to 2A and the other way around with a capture of the over and under-shoot on the scope.

[@jeffescortlx]

If they made a dual output it would be perfect. I just got done reviewing mine and I love it!

Quite like this PSU, probably gonna get one for a play. I wonder on robustness though and maybe scope for modifying. Great video.

[@jeffmcclain]

I sure would like to identify at around 15:49 if there is an easy point just prior to the relay out, I assume, where you could hack the feedback voltage to incorporate some 4-wire Sense circuit / leads to outputs (even if you have to go out the back) with 100k Rs shunts to the internal supply. I'm going to have to trace some of that back, and sure wish they would include schematics in these manuals, but they are so worried about copy-cats they even laser off the IC's labels for export and reverse engineering... I think it would be directly applicable to whatever you find for the voltage drop from internal to even at the terminals under load at 6:35 you would just be pulling in a typical Rs 4-wire sense circuit feed (maybe add some over voltage protection there too).

[@Bonjour-World]

No mention of the knob on the upper right ????

[@Tim_Small]

At 8:50, I was wondering if some/all of the observed voltage undershoot when connecting the lamp is actually the lamp heating up, and so increasing its resistance?

[@Doile911]

I'm thinking about one of these or a basetech BT-305, since i have one of those available to me at my workplace. What do you think? (the basetech is only 30V 5A with coarse and fine tuning for voltage)

[@TheRealSasquatch]

how would this cope with a simple unregulated transformer/rectifier psu feeding it?

[@Gengh13]

That would be a great video idea, measuring the psrr.

[@sdgelectronics]

You wouldn't be able to use it directly without some large capacitors. The dips in the rectified waveform need to be greater than 60V,but the peaks no higher than 70V. I suspect its not possible.

[@Frustratedfool]

Hi Steve. I bought one of these but had an issue when powering it from a multi tap toroidal I use as an isolation transformer. One tap is 48-0-48 at 7 amps. I run one side of this through a bridge rectifier and measured the DC output at 48v when the transformer is at full mains voltage (240vUK). But when I link this winding to the 6006, the voltage shoots up way beyond expected. I used a variac to being the voltage slowly up and I was reading 48v DC on the input when mains was at 110v ac... just over double what I was reading without the 6006. When powering the 6006 using a linear supply it behaves normally. Any idea why it boosts the Input voltage when using the toroidal transformer? Thanks.

[@sdgelectronics]

Do you have any capacitors after the rectifier?

[@Frustratedfool]

SDG Electronics thanks for the swift reply. No, I have no caps after the rectifier ... just direct into the RD6006. I was going to add one across the supply, but didn’t have one with enough capacitance/voltage to hand...not that I am entirely sure what the capacitance should be. I was told 1uf per 100 mw (max), but needed to do some research to check. Thats one of the reasons I used a variac... to check things were going to work. The unit powers on after around 10 volts but will stay on until you drop down to 5 volts. It just goes a bit wild as the voltage increases with the 6006 connected. Happy New year!

[@tonysfun]

Very nice video about this unit. I just purchased one and I'm learning it's functions.... Thank you very much!

[@gman76utube]

Nice video. You mention a relatively low sw freq of 150kHz and said if it were higher you'd get better efficiency. Actually it's the other way around - higher freq would yield lower efficiency.

[@AdiGitalEU]

How is the OVP and OCP implemented? Looks like it’s software based. Did you measure the delays or the behaviour in general?

[@movax20h]

Looking at circuity at the back, I think it is hardware based. At least the OCP part and current limit. The OVP, well I have no idea. The I-set is definitively hardware based. There is no way to make it software and work reliably. But who knows. Worth testing or tracing the circuit.

[@AdiGitalEU]

A bit odd that a P-channel MOSFET is used. Is the control voltage negative with respect to ground?

[@Mr.Leeroy]

n-channel would require high side driver, so probably more expensive..

[@gman76utube]

@@Mr.Leeroy And Nch gate would need to be pumped higher than the output. It's a positive supply, the Pch gate is pulled low relative to the source to turn on. This is fine except for low output voltages ... maybe there's a neg 5V supply to pull the gate low enough for Vout < 2V or so.

[@guillep2k]

Or maybe you've chained them at the Fluke, which is wrong too.
