Or do you think I could use these for Hypex UCD's?

Sincerely, with that size, I don't see the advantage ;-)

That would take up a good chunk of the case sure, its' competitive on a cost basis. The advantage is regulation I guess.

They're meant for audio so I guess you can use them. Maybe email them and let us know what they have to say?

Options are good to have.

The price is not all that bad? The layout looks funny though, and I hate the fan that's on there...

If this is regulated, does it mean you don't need caps anymore (or just small ones) between smps and the modules? Seems nice for UcD...

There's bigger & smaller amps as well.

The 2400 seems to have 20A in the 60/0/60 version... that's a lot of juice!

Hello all,

From the looks of the picture on the website, it looks that the output LC filter uses a quite small cap. That may not be bad, however, if you add additional caps, you may end up with oscillations as the feedback loop (for the regulation) may be optimized for a certain capacitive load. To keep things stable when more caps are added, you may need to change the feedback loop. Note that each UcD module also has power supply decoupling caps on board which add to the capacitive load. Maybe someone has tried this supply as I have seen this supply mentioned in some of the other threads. Would be interesting to know what peoples experiences are.

Best regards

Gertjan

Hello,

I have ordered some samples of this SMPS. And I can not recommend these in combination with our UcD modules.

Thereby if you see them in real life, the PCB is really HUGE!

Regards,

Jan-Peter

Jan-Peter!

Could you make some photo from that SMPS?
From the top, from the bottom, from everywhere:-)
To see the details, what topology does that SMPS use, the component placing, etcetcetc...

Jan-Peter says no, that's no for me as well. :-)

You may buy them for a very resonable price, if you are interested please send me a PM.
