Calling electrical experts - Din rail PSU 240vac to LV dc

["uktiggs" <david.yeend@xxxxxxxxx>]

Hi,

I am fed up with the number of plug pack PSUs which require numerous
mains sockets and take up so much space.....

I have gone through the loop of one plug pack per output level and
splitting the outputs with terminal block - still don't like it as it
looks messy.

I have thought about using one big powerful DC PSU to drive a
concoction of regulators giving individual outputs at multiple (maybe
adjustable) voltages. I think someone else on the list has done this
but I have decided against this due to time etc.....

So my solution is going to be to purchase some DIN rail mounted PSUs
and put them in an enclosure with a cable exit feeding into tunking.
Overall it will probably be no better than my array of plug pack type
PSUs but it appeals to me on the basis of being neat, tidy and, I
think, a little more compact than the current solution.

Anyone got any comments on this?

My question for the electrical experts is:

I am worried about the mix of Mains supply and Low Voltage in the
same space.... My intention is to have a single cable for 240v coming
into the enclosure which will terminate into a standard 13A plug.
Inside the enclosure I will need to split the supply to each PSU. I
will probably need to increase the number of outputs from each PSU.
What, from a professional point of view, would be the best way to
address these considerations? Terminal block? If so is it possible to
get it to mount in a tidy fashion on a rail? Is there some form of
rail mounted bus bar I could use? Are there any regs concerning what
happens inside distribution boards etc. which would apply in this
case?

Thanks for any help you can give.

Regards,

David
