Now you know why the rest of the world uses 250V! Damn Edison and his FUD! I have the RD6006 and frankly that is all the power I'll ever need, but I cannot believe how far they've pushed the power with the same physical design. I have the bulk PSU mounted on the wall under the bench and the RD6006 wall mounted above the bench. I'm trying to use all test equipment this way to avoid it's depth crowding me off the bench as it does yours! One reason I really like the Micsig scope! One oddity with these units is that there is a mechanical relay inside, but this is only used for charge termination, not when you switch the output off manually or on a protection trip. I cannot understand why they do not use the relay to cut the output faster. Also worth noting that the RD unit is not isolated, so you can't use two RD units on one bulk supply for dual rail.

@@zoom_h2625 The RD60xx is a synchronous buck converter (not isolated). The negative side of its input is connected to the negative output terminal. It depends on the bulk PSU for isolation. Eddie has used a switch-mode unit for this. Jerry used a linear PSU. Neither of them could get a dual rail unit using a common bulk PSU because this would result in the two RD60xx units having their negative output terminals connected together. I saw Jerry's video before and did not understand what he was trying to achieve. For a hybrid PSU you want a switch-mode bulk converter with a linear final stage to finesse the output. Jerry's configuration is the wrong way round and gives the worst of both worlds. Just imagine the size of the transformers and capacitor banks scaled up to three times the power for the RD6018!

One thing that I have noticed is, that the switching mode power supply (AC/DC) does not have a PFC. Powersupplys at this level of power should definitely have one. That's typical for power supplys from China or cheaper ones Maybe you could have explained the topology of the power supply a little bit. (The coil on the secondary side is not only for filtering. It stores the energy in one halfcicle. The smaller winding on the secondary coil is not for current sensing. It's some kind of secondary and powers the fan. In conclusion a great Video👍

Does the dc dc power supply save the previous setting for output volts etc and kick straight back in when you turn it off and on again. Or do you need to manually hit power start or turn the volts and amps knobs back up again. Figuring if it would be suitable to smooth out the fairly erratic voltage output from a wind turbine. Which can go to zero quite often so the psu would turn off... But would it turn back on when the wind turbine spins again and puts back out power to it.. Many thanks

Thank you sir for another informative & well done video! Is the power supply that comes with the RD6018W(Whole machine) from your Amazon link for $199.99 the same as yours? If not, what is the model of the power supply you purchased?

The cable says 0.5 mm², which is area, not diameter. This is about 20 AWG in the US. In Europe and many other parts of the world cables, cords and wires are commonly marked with mm², we don't use the AWG system at all. Common sizes for power cords with IEC C13 plugs are 1 mm² (17 AWG) for 10 A and 0.75 mm² (18 AWG) for up to 6 A. Current rating might vary among manufacturers and cord lengths and might also vary somewhat between 120 V and 230 V systems. It's a good point though that you shouldn't connect a random cord to a power supply, check the wire gauge first.

@KissAnalog

Жыл бұрын

Thanks for this great feedback Johanh! Yes, that is what I showed in the video, the cord that was heated was only 20 AWG. You are so right - random cords can be dangerous. Always check the rating or size of the cable.

A more difficult test for these power supplies is to switch the load instead of the source to check for overshoot, etc. This is especially difficult if the load is reactive. Some supplies will overshoot badly in such conditions due to the output capacitance of the supply itself, though the Riden (Rui Deng) supplies usually do acceptably well.

Though Max at turn on is a useful measurement, the HT206 doesn't have a true Inrush mode, so Max will only show a portion of the inrush depending upon the meter's standard time resolution. Max is not the same as Inrush, even though commenters sometimes have angrily told me otherwise ;). To get a better Inrush measurement on a Habotest (Hototech) meter, you have to jump up to their HT208 series. Even then, it's hard to know what the resolution actually is or what standard we should use for inrush mode. Fluke's present-day standard is to take 400 samples over a 100ms period after the sampling is triggered by some rise in current. The 100ms may start as soon as current rises above some hysteresis point above or below 0, but that's unclear. The important bit is that we take measurements multiple times per millisecond, which Max mode on budget meters will certainly not do. Still, Max is good enough for many purposes; I'm not arguing that it's not.

@KissAnalog

2 жыл бұрын

Thanks for this great feedback! I agree with you that max and inrush are different modes for the meter, and some have both which maybe proves your case;) Although, some measurements both modes will capture near the same thing as you point out in the sampling time. An inrush is typically a really cool feature added to more expensive meters. Maybe you get arguments from Fluke guys who often don't have inrush unless they paid for one of the better meters;) Here's a video that I did on 5 different Kaiweets meters: kzread.info/dash/bejne/dW2iy5aYkq_Wgps.html

for 10A, 0.75mm2 is the absolute bare min and I'd not use anything lower than 1.5mm2 as 0.75 is likely to hit 40-45C over ambient at 10A. Btw, the plug is rated 10A but just the plug, itself.

@@KissAnalog Greetings from 240 volt region and thanks for all your videos. Oh yeah, after visiting central america and their kamikaze showers i fully understand why they use 110 volts. For all who don't know those showers: upload.wikimedia.org/wikipedia/commons/0/0e/Chuveiro.JPG If you feel it you have to slightly bend your knees. Something you wont forget ;)

Thing is, we do have 240 volts as well, homes here have a center tapped 240V feed. But 240V is only used for high power items (electric heaters, clothes dryers, kitchen stoves, etc). Things which don't have crazy power requirements use 120V, which is from one side of the transformer to the center tap.

The mains cable is an usual chinese joke.

LOL thanks!

I have a big box of battery powered tools without batteries , voltage from 12 to 20 volts, what spec power supply would I need to check them out, I presume they operate at higher amperage

This would be a great power supply. I think you would want at least 20V variable power supply and a current rating 4x higher than the power that tools are rated for - so it would cover spin up or turn on transient.
