PSU problem

[buldo]

Hi everyone,

I buy a prusa i3 and I have a problem with the Psu. When I apply 220 volt beetween the pin "L" and "AC" there is ov beetween the pin "com" and "v+".
I check the voltage with a voltmeter.
The green led power does not light up.
The switch inside the PSU is on 220V

Tell me if the PSU model S-180-12 is ok

Thanks for your help.

Hy!

I think that must be ok, you just need 12V DC for power look the original one but i think that is the 18A.

Did you check the input fuse in original PS, also check the solder on pins where you connect 220V AC

Thanks for your answer, I can't check the fuse because he is inside the psu who was sealed by a sticker for warranty. But only thing i can tell you that the fuse seems good (not interrupted) when i see through the cover grid.

It's the same thing for the pin sealed by stiker, but seems ok.

I think the psu has factory defective

Hi,@buldo
How is it going?
Normally,the green led will light up when you switch on the power,and it should have DC output if you can have AC input on the PSU.
Otherwise the PSU has a problem.

Hi,@William
To resume the history , i have buy a prusa i3 with an official retailer.
On the first power on of the psu I can see there is a problem. My job is electrician that's why I'am sure the psu has a problem.
After I inform the retailer he request me to post a thread on this forum and (quote)" I will help you follow up with our technical colleague."

But there is no help and the retailer refuse to proceed exchange without agreement
(quote) "We can't resend if without the confirmation of our technical support."

I have no solution and i am waiting since 2 january ...

Your PSU is dead.
Just contact the related seller and replace a new one!

Yes the Geeetech techincal support reply to me now by email. So I would like to let you know that me and a my friend engineer measured the current absorption with a current meter about the Prusa i3 MK8 and we've seen that it is higher than the 15A delivered by the PSU. The supplied PSU is underdimensional!
