How to plug 2 psu3 with 1 power inlet

2016-05-26 by oabbeloos@yahoo.fr

Hi all,

Sorry for the noobie question, but i would like to use 2 Doepfer PSU 3 in my case but with only 1 power inle, and i'm not sure about the way to plug them together.
I found a scheme (on the Doepfer wbesite) to plug an inlet+switch with 1 PSU3, but i'm not sure on how to do the same with 2 PSU3.

I made a scheme, based on the Doepfer version for 1 PSU, but for my 2 PSU.

Do you think that it's ok to plug the second PSU to the first one ?

In the Doepfer scheme, the ground is not plug anywhere. Is there any reason? Maybe it's not necessary to plug the ground....
In my case, can i do the same thing without any risk?

Thanks in advance for your help

I'm also curious about this. Looks like nobody has chimed in with an answer yet.

Two or more power supplies can be connected to one mains inlet. Ony simply has to install the correct fuse into the inlet (twice the
value for one PSU in case of two PSUS) and wire the mains inputs of both supplies in parallel to the mains inlet.

But as these works affects parts, pc boards and cables that conduct mains voltage (230/115V) carrying out of these works is allowed
only for experts or authorized personnel who are familiar with all valid safety rules. Laymen are not allowed to carry out these
works ! Danger to Life.

i have done this myself, it's quite straightforward, but agree with dieter in as much as i'd be very reluctant to advise someone on how to do it. it comes under the category of "if you need to ask then you shouldn't do it".
if you have a local "old style" electrical shop near you then get them to do it for you. it won't cost much, maybe 1 hours work, and it will ensure you don't blow up any modules or even yourself.

I fully agree but from my experience customers react a bit angry if you give that answer :-)
