3 UCDs per SMPS?
« on: 22 May 2013, 08:29 pm »
Is it possible to use one SMPS- power supply for three UCD units? For example SMPS1200A400- should have enough power to be used with 2 x UCD400 + 1 x UCD180 in a three way setup. Is there any reason why this would not work? Or would it be even possible to use it for 2 x UCD400 + 1 x Ncore?

2xUCD400+1x UCD180 isnt possible. 180 doesnt use the same voltage the 400 does.

The UCD180 works with a supply voltage from +-25 V to +-50 V, the UCD400 needs +-45 V to +-65 V, so at least in theory you could use a common +-45 V supply.

Yeah you are right, but it isnt possible in the smps1200a400 setup anyway.

You could attach 10 amplifier modules to a single SMPS power supply if you wanted to.....as long as you don't exceed the power rating of the SMPS supply.  And, of course, you have to be inside the nominal voltage range of the multiple amplifier modules...if they're different.

I currently have five UcD180ST modules attached to a single SMPS400A180 supply and it works fine.

Cheers,

Dave.

But is there any power supply that could be used both for NCore and some UCD unit?

SMPS1200A400 can power certain UcD amps (sorry can't remember which UcD amp or amps) and Ncore NC400. 

In my Hypex Build Service I use SMPS1200A400 for stereo NC400 amp and bridged NC400 mono bloc (1200W @ 2 Ohms, safe to 1 Ohm though no 1 Ohm rating).
