WattHour ,you do great review.. Could you do a setup and test for the XY6020L DC buck converter.

[@kalashnikov_47z]

I have Ordered WZ-6012 module Not WZ-5005 Is WZ-6012 is better? I have 36V 10A Powersupply can i use that as input? BTW ! great reviews 🥳

Question: If you were offered a free benchtop power supply and there were two supplies, both new of the same rating, make and quality (you don't know the prices); one was a linear supply and the other a switching supply, which one would you take?

[@WattHour]

Of course switching power supply without any hesitation.

[@robert574]

@@WattHour Even if they both just had a 4 digit readout, CC and CV, with no other functions or readouts? Wouldn't the linear supply have less noise on the output?

[@robert574]

@@WattHour If i understand it right, the linear supply will have a transformer and the output of the secondary and the supply will be isolated from ground, but is the output of the switching supply isolated? I guess they both could have a transformer and isolation. Are some switching supplies isolated and some not? (I'm in the US with 120V power one side neutral grounded)

[@WattHour]

There are isolated converter (switching) you can buy. if energy is does not matter, then use linear. Linear is wasting sometimes like more than 50% .

[@robert574]

@@WattHour I have been buying some new power supplies and picked up a breakout board for a computer ATX supply. Those are switched and clean enough for computers so no problem. A linear supply will have to burn off a lot of power and most all of the supplies are switching now. I'm still trying to figure out how to test the limits on a supply and it's tough without an electronic load. I have this massive spreadsheet of light bulbs, rheostats and Christmas tree lights I have and I'm about to give up trying to get it to come out right. My first supply is 120VDC and I don't have anything adjustable to feed that into, but I think for the 30V supply I can just feed it into a buck converter then burn it off into a load and adjust it until I hit the limits. maybe.

[@igorkvachun3572]

Yes👍 🔋⚡

[@robert574]

Why did you put heat shrink on the ends of your leads? it looks like you soldered a smaller wire to the end of a larger wire. Was that to get it under the screw terminals? Maybe you wrapped some of the strands around the end of the insulation and then soldered them? hmmm.......

[@WattHour]

yes. there were lot of threads of wires and I cut half of them and then soldered them to keep them together and fit securely under the screw.

@@WattHour Hello Please reply Can i use 36V 10A Powersupply with WZ-6012?

[@mtrltoolman]

I saw a video about buck converter that can be used as a bench power supply it was in your channel you tested it and it was good product but i can't remember which one is it 😅 can you please help me.

[@WattHour]

Hi, I have so many video on buck converter, just search my channel for "buck" converter you will see all of them. learn how to Search for a Particular video in a channel here bit.ly/findKZbinVideo
