Has anyone built a 5 channel version of the ncore? I was wondering how you would wire up the power supplies.

Not 5 channels, but I have done 2 x 4 channels. Each pair of nc400's sharing one smps600 each, with a pretty straightforward T-split of the cabling.

Hi, I am building one right now, 5 x nCore with 5 x SMPS. I wire them individualy to a splitter and from there to a Softstart. I consider to use a second Softstart because of the 6 A limitation.

So what ever happened to the folks working on some nice custom cases for the ncore ?

I can see a softstart makes sense with a big toroidal transformer, but does it really do anything useful with a SMPS?

It might. The inrush current is fairy high when the mains side capacitors are charged. I have six SMPS600 powering up at the same time, and the lights in my room really go dim when I power it up.

What do you think of a second one?

Default Intermittent sound and shut down eventually

I have received my two sets of n-core 400 and smps 600 last week, and assembled them this week.
One of them is working pefectly, but the other one worked for just a brief moment. There was sound, but is was intermittent, every 1 sec it was interupted. After some time, there was a click of the smps and since it has been clicking so far (every 2 sec; no lights on nc 400). The SMPS disconnected and powerup just clikcs once, so seems ok.
So it seems it is in some sort of protection mode? DC I suppose?
How do I clear this error state?
I read some threads about not well calibrated dc in and out output and applying 3v to pin 1 and 2 (what does this do exaclty?).
Can anyone share the instructions how to calibrate the DC setting (if that would help to solve the problem)?
I already contacted hypex, but no response yet (it is weekend, so I guess it will be next week).
Can't wait before I have two working n-cores!

Any tips/suggestions what I can do? Thanks in advance!

Two softstarts in series? Both will probably have the same turn-on delay, so the effect will be zip.

Wouldn't a simple delay circuit that turns the SMPSs on in sequence be better? Not sure what happens with a SMPS when you limit the input current with a resistor....
