Hi,
I'm totally new to Class-D + SMPS. So far I used the Hypex modules together wit a transformer. So my question is quite simple:
I want to supply four UCD180 modules with one of the Hypex SMPS. Which one do I need then? The SMPS400 or the SMPS1200?
Background of the question (why I'm confused):
In the manuals they write that an amplifier draws twice the RMS power from the power supply. That would mean: 4 x 2 x 180W = 1440W
But in the manual of the SMPS they write that for music signals the max. power consumption is 1/8 of the RMS values.
So, what is the right SMPS?
R.

Hm, I read it but I'm getting confused more and more. Sorry. I don't see the answer yet. I only see questions at the moment. 🙁
I spoke to Hypex about running 6x UCD180 off a single SMPS for a three way application. Hypex said that SMPS400A180 would be fine, given that the tweeters and mids would not require much current. Hope this helps.
