Addac please, answer me

Post by DonKartofflo » Thu Feb 19, 2015 2:00 am

So since i dont get a reply via email, maybe it will work here.
I really would like to buy an addac closed and powered tabletop 12u but nobody seems to know wether the psu is switching or linear.
So please, i guess it takes 30 seconds to tell me. Not a lot of time spend for selling a case.

Hi DonKartofflo,

As far as i know the addac PSU are switching.
But he puts extra power conditioners with massive heat sinks between the PSU out and the bus boards.

The closed 12u was designed for me ;) one tip, get 2 PSU in it as i did.
1PSU may be not enough with the modern mA sucking digital/hybrid modules. Some Addac modules even if analog use a lot, 802V2 @ 150mA... over 10% of a standard doepfer PSU... and just 12HP used...

good idea! this was exactly what i wanted when i saw the open 12U released.
Yeah I think I should get two, 2200mA for 12U is a little tight indeed.
Do you notice any bleed/switching noise on your case?

Cheers!

I didn't notice anything compared to my Doepfer racks.
Anyway when i had power trouble it was always with skiffs that came with bad PSU and regulators on the busboards.

I perform most of the time now in my oldest addac cases having no conditioners between the PSU and busboards, no trouble.

I regret selling the 12U case, i went from one 12Ux84 to two 6Ux104 and 6Ux84 instruments. Not enough space to keep it. :(

I thought this one was a linear PSU but I can be wrong :despair: : http://addacsystem.com/product/addac909 ... dac909e-4a
