I always use linear power supplies due to noise. They are almost as clean as a battery, in many applications this is essential. A lot of the background noise heard within the radio spectrum nowadays is caused by switching power supplies. I have a couple that were made back in the late 70s and more importantly they are in almost daily use, you may occasionally get coil whine but this is easily solved. Downside is they cost more money and aren't as efficient. I do have a switch mode supply a thurby tsx3510, which is now at least 10 years old and proven it's worth.. over a grand new. Like the video says. It all depends on what you want it for, but be sure to buy a linear if using RF or highly sensitive prone to noise interference circuits
Hi, Very good video, I have two power supplies, one being switching and the other linear. When I use the switching mode power supply on an amplifier I built, I get all kind of distortion, however, when I use the linear power supply, the amplifier distortion is gone... You have helped to understand why this is so. Thank you for sharing this video...
As several folks have mentioned below - the comparison chart which is displayed at 2:31 is incorrect. Leaving it uncorrected after folks have taken the trouble to flag it up, and after you've promised to fix it, and after 2 years has passed is irresponsible, and reflects badly on your company. The video is easily sorted - but a bad reputation isn't.
Anyone who listened to the information in the video explained or has half a brain can figure out they 2 were just swapped accidentally. Nobody is really going to avoid the company over something stupid like that on social media. Get over it.
Unfortunately you can't "edit" a TH-cam video like that. You have to delete it and replace it with a new one -- the original is totally lost even though the change is trivial. So you lose the history, it breaks the links for people who have references to it, etc. It often just isn't worth it.
I'm planning to making a project like charger. My question is, can i use other relay like motorcycle 12v 5pin relay for my project? Because they're the same 12v and 5 pin?
Hello, Thank you for commenting. I am not sure if I understood your question correctly, but during switching, transient response may be a concern, so please consider referring to the technical data on our website.

You know you're being hoodwinked, when he seller describes them as a 'UK Variable Linear Adjustable switch-mode Lab DC Bench Power Supply 0-30V 0-10A 220V' Something is going to be dodgy, if it costs only £50 and was made in China!
Switching power supplies can not be used in parallel meaning you can not put 2 of them to double the amp output. You can with regulated ones. Switching will start fighting each other.
Thanks for this but if you are not going to correct the mistake where you identify the linear system-ply as using PWM then you need to take the video down before you confuse even more people. You said previously you would, so why hasn’t it been done?
I used a linear power supply for my laptop charger to charging battery , but there is a problem about connect / disconnected charging every second... why?
I’m a rank beginner in the electronics field but knew something was wrong when I heard one thing but saw the opposite in the graphics. Irritating. After two years and no correction this is terrible advertising for whoever made it.
and your one sad puppy for humanity, sitting on social media and whning about something you dont understand. exactly how should he edited it.? he explains it in details so even you can seee what is up and down.. that one segment in the charts is flipped...yeah mistakes happens..but instead of saying thanks for explaining it, you hurry to whine about a minor graphical mistake. come on the dude just spend all the video explaining pro & c0ns so it doesnt take a phd to realize what benefits they each have. dang.. characte3rs like you, gotta be one handfull to be around.
FYI - your summary slide shows the linear power supply as using PWM...and the switching PWS using a transformer
Oops! Thank you for the heads up. We'll try to edit this and re-upload as soon as possible.

How about using a noise filter down the psu ?

Isn't it mistake on the image on 2:45? I think PWM is replaced by place with Transformer on the height of "How it works".
i was thinking that too
fantastic video...short and to the point. Thanks!
Thanks for sharing . Simple and easy to understand

What is the correct chart? Thanks
@@j.lietka9406 On the 2:31 chart, the "How it works" row for Switching should say PWM, Linear should say Transformer.
@@RobDunsford ok thank you for the correct info! Any good word on a tacklife brand DC power supply? Thanks

What about the switching noise of the rectifier bridge in the linear power supply and the typical 60hz/120hz humming noise?!?
Great this what I needed to know! I am a novice looking for my first dc power supply :)
Nice presentation and really great products.
But where in Europa (Germany) can I purchase your products?

the slide shown at the end seems to be wrong, transformer and pwm are on the wrong sides?
Excellent explanation...good job.
So, which one do you use for working on audio electronics?
In audio electronics you usually have high frecuencies, so you better use a linear one.
For audio linear are considered better because of low high frequency noise
So what I gather for an electrolysis plating use linear would be the better option or does it not matter? Any assistance would be gratuitous.
Nice explanation 😎😎😎
Good info

Video is great but the image is wrong. It states linear=PWM and switch=transformer. 👀
Thanks, very useful!
Nice information... Thanks
in the table there is one error. Linear not PWM.
My vote.....go Linear. 👍
Graphics are misleading. Someone who knows about these supplies should be sitting with the editor and go over the video before uploading.
Where are they misleading?
@@altuber99_athlete Use the (electromotive) force, Luke!

@@rb6725 Thanks. I see the mistake, where it says SMPS use transformers and linear supplies use PWM.
First line in the graphic at 2:51 is wrong - reversed.

is there possible convert Linear Power Supply to Switching power supply?
Why would you want to do that?
@Dimdim big brain
Linear is more expensive. Why would you do that?
NO.. It is a crazy idea.
hi how abot the power consumption?
because I have linear and switching power supply, and iwant to use the lower current consumption.
tnx
Switching power supplies consume less power. and they are more efficient.
