Hi, optionally you could self edit the duplicated post and remove its contents.

If I may, the new model raise questions
- is the DPS-500/UR due to replace DPS-500S ?
- if one want to choose betwen the 2 PSU models by comparing those, then what would be the respective advantages/disadvantages for each?

Really? but I see no edit pushbutton.

Primary differences between / S - / UR

The "S" version, is fully regulated by the owner synchronized analog power regulator stages, with dual feedback, and offers top performance as noise, and speed of response. if used in audio power amplifier is also capable of maintaining the voltage perfectly balanced between the two rail vcc, during the current demands, we know well be unbalanced. this is an additional benefit for an audio amplifier.

The "UR" is like an unregulated smps but with two new features that go well in the case of audio amplifiers.

1) the output voltage is independent of the ac line voltage, so we can adjust 62V for example, and see that they are very stable.

2) the output voltage is dependent from the current request, (as in the case of traditional unregulate smps), but with a percentage of fast regulation. we have set this value to about 30%.

So we have:
A smps very clean (this also uses a feedback loop) as opposed to a traditional unregulated.

A high ratio of power / size / heat
A well-fixed output voltage.

For me. Said the pros and cons, it is not easy,maybe is "condition" dependant. I think this version can be well accepted, in place of a large toroidal with big caps.
Out doubt, the "S" version, is "for us" in terms of measurements, we can not imagine better.

Thanks a lot for your clear answers about the differences between the 2 PSUs.

I guess you are right for the present case perhaps for one of the following reasons though I don't know which one is at stake:

Edit: I could edit this post immediately after so perhaps it is just time limited on this thread.

did some of you received their DPS-500 and tested the FO?

Ciao!
Do

Not till now.
FO is waiting for the right juice ...

AudioPower modules just received.

Here you have some pictures.

Pictures?

 

[danny_66]

Looking nice

Looking forward to mine, they just left Rome according to UPS.

 

[danny_66]

They have arrived and already found a comfy place in the case

I'm about to buils 2 monoblocks.
I have 2 DPS-500/UR that I'm going to connect to 2 nCore 400 power amps.
Should I add some big capacitors after the power supplies ??
