I gave up on this thread already.  This new 18-minute clip shows a "magic" self-powering setup, yet again.

For starters, that looks like a 5-volt DC power supply.  What the hell is the DC output of a power supply doing driving the primary of a transformer?  If I am correct and we are looking at a small AC-in-DC-out switching power supply, that makes no sense.

Somewhere in the second half of the clip he measures the input to the switching power supply in "self-run" mode.  If I recall correctly he measures something like 5.6 volts DC.  The power supply has an input requirement of something like 96 to 250 volts AC.  It doesn't make any sense.

Finally, I attached a frame from the clip.  He has broken the seal on on the power supply.  That would tend to indicate that he opened it up for some reason.  One can only wonder why.

Are you saying this video is a fake? Just because it violates Conservation of Miracles?

Hey, at least he's not using one of those silly pot core ferrite things.

Maybe the DC output of the power supply is just used to bias the core, and the input power to the supply is pulsed. Or something. Right.

Indeed!  TK....

Meanwhile.... Google "refuses" to cough up anything on a "Mean Well AS-25-5."

Google tries to force you to look at the "Mean Well RS-25-5."   (see attached)

What that normally means is that the AS-25-5 is identical to the RS-25-5.   The AS-25-5 is just an "OEM" version of the RS-25-5.  The reason for this is to prevent someone from buying the cheaper RS-25-5 when that part fails in their printer (as an example.)  The printer manufacturer wants to force you to buy the "authorized" part from them only at a much higher price.

That's another story from the Naked Electronics City....

I can see nothing wrong, look at the video again, give the man a chance as you must of been distracted.
While I'm on, has any one managed to get the ever lasting torch to work, i had a look at it on some Vero card and find it almost impossible to tune the cap on pin three with the coil for resonance as the chip tries to chop the cycle and the 4069 and transistor just make the wave form jitter, with no over unity even with the copper tape between the windings. On one of the vid's the PCB has no 4069 at all but the builder does not show the top pane of the PCB to the viewer. I cant get any of the options to work.

Hey MileHigh,

EBay my be a good resource for this Power Supply: Mean Well AS-25-5

Hope this helps!

The OUTPUT of the ferrrite cores transformer feeds into the mains INPUT of the PSU. Thus the voltage has to be at least 100v AC although the frequency could be hundreds of Hz..   Use of the PSU offers a very wide range of input voltage from 90 VAC to 280VAC  and system stabilty as well as some power factor correction.

The 5v OUTPUT of the PSU are  the black wires feeding the vero PCB which in essence is only a switching boost converter.

Makes sense to me:)  Its a simply looped device.  The excess energy can only come from the ferrite conversion which has a COP of at least 3 to cover the system losses and SMPSU typically 88%.. 

BTW its ONLY the typology of the system which is important and NOT the PSU part numbers!! Any PSU could be looped including old ATX PC power  supplies.  The "magic" is only in the  ferrite coil construction and coil winding detail.

Hi,
somebody know which type of diods is on mains enter  on the RS-25-5 ?
they are low frequncy ? how they can keep HF from generator?

Bolt,

You are absolutely correct about the AC input and DC output connections for the power supply.  I let my mind trick myself for two reasons, 1) I am so used to seeing black wire used as a mains power wire, and 2) I associated the switch with a mains power on/off switch to the power supply because you can see that the power supply does not have an on/off switch and that's what you would "normally" do for a power supply like that.   So my comments about the DC output of the power supply going into the transformer and related comments are wrong and I retract them.

But the rest of your comments are pure fantasy.  You cannot loop because there is no COP 3 from the "ferrite conversion."  Have you ever measured the in and out energy for a transformer ferrite?  I have and it's under unity I assure you.  I don't know why you would even believe that.  Just do the bench tests on the pulse and AC characteristics of any transformer and find out for yourself.

The seal on the power supply is broken.  That's one of many possible explanations for this clip.  He was too lazy to even try to peel off the label very carefully with an xacto knife blade and then put it back.  You can buy a battery in just about any cylindrical shape and size that you want and put it inside the power supply.   A switching power supply doesn't have particularly large caps, but you could do a very professional job if you wanted to.

Does he measure the AC voltage across the white wires in the clip?  I am not sure I only watched 2/3 of the clip.  But even that could be easily faked if you wanted to.

Where is the scientific proof that ferrite conversion has a cop of 3?

What are you talking about? The PINOUT of the power supply is given in the Data Sheet that MH found, and the colors of the wires are perfectly clear in the video.

The BLACK wires are connected to the MAINS INPUT of the power supply. The WHITE WIRES are connected to the DC OUTPUT of the power supply.

Here's the Data Sheet for another branded 'AS25-5' PSU. Note that the thing is a mirror image of what is shown in the video. The pinout, though, is standard, if reversed: The MAINS input terminals are close to the edge of the case and the DC output terminals are nearer the center, with a gap next to them; this gap contains the fine adjust pot and the green power-on LED.

Unless the pinout has been altered internally, the PSU shown in the video has the WHITE WIRES connected to the DC OUTPUT terminals and the BLACK WIRES connected to the AC MAINS input terminals.

No the RS and the AS are not the same.

No the datasheet you attached show 1 & 2 are DC and 4 & 5 are AC.
