Hi Jan-Peter et al,
that's good news for everyone waiting. 😉
The price seems reasonable as an introduction (considering the demand...).
But I'm actually in need of the 400W and 1kW (or whatever higher power) versions. 🙁
Can you estimate them being in schedule for this 'season' (i.e. summer)?
Thanks,
Sebastian.

We have started with desiging the 360W version, it's a dual 180W SMPS transformer. If everything works as we hope, we will have this version soon in production. Probably in 3-4 months???
The more powerfull version is schedulded for after the 360W version.
If you like to talk in 'seasons' it will be not earlier as winter 2008....

That's good to hear. It would mean a medium power solution (to support UCD400s) this year.
And I take it that two combined 180W SMPS would work alike in case I can't wait that long. 😉
Thanks for your reply, Jan-Peter.
Cheers,
Sebastian.

Yes, you can use two SMPS in parallel, or in series. All is possible.... 😉
We are working on it!!
However we are now VERY close to put the SMPS in production.
This week we have checked if it will pass the CE, so foar this is no problem at all.
The SMPS is extremely stable, now full power at 20Hz at 120V line voltage (180W). Output voltage stays very stable, compared with a liniear transformer + power supply much less voltage drop, less ripple.
You can turn the variac from 120VAC to 250VAC output voltage stays 2 x 45VDC. The efficiency is 81%, perhaps we can slightly improve this, the efficience of a 160VA transformer + power supply is 90%.
With a minor modification the pre-production batch is so stable it could be sold.... 😉
Anyway....next week we will order everything for the production, and i expect to have these in stock in about 4 weeks now!
Do have some patience

Do you have more information on the voltage drop and the amount of ripples?
I will post next week a couple of pictures, SMPS and liniear power supply.

Question about SMPS
Hi Jan-Peter,
i am looking forward for the SMPS for my UCD180HG-HXF. I want to ask You, if it will sound better using the HXF-regulators, or using the +/-12V Supply from the SMPS.
best regards
Thomas

81% efficiency is quite poor, particularly for a single stage converter, it's 36W losses for 180W output...
To me the low idle losses of 2W (according to the datasheet) are more important than extremely high efficiency since I dont think I will listen at full power whole time... I'm looking forward to see the SMPS-180 in action 🙂

I agree with both of you! 🙂
But the next, higher power SMPS should have significantly higher efficiency!

I can imagine you are very busy working on this project, but I'm very impatient regarding this project!
Any news?

The SMPS180 is now on the Hypex Website. You can get the PDF at
www.hypex.nl/docs/smps180.pdf
The lead time is 4 - 6 weeks. They also have some new OEM-UcD-modules.

I'm sure the lead time will be much shorter once they have them in stock 😉
Those OEM modules aren't new at all. Bryston uses the 180 version. Either way they are not for us.
Hello,
we are now very close to release the SMPS 180W, finally.... 😉
Hereby already some pictures of the first production sample;
Later this week we will release the full datasheet and add the product in our webshop....

An externally hosted image should be here but it was not working when we last tested it.

Hi,
We have fist concentrate our selves onto a rocket stable SMPS design, the design is a single flyback converer included with a PFC.
The SMPS is build according to a Class-2 safety standard. And the used Y-capacitors are 2x470pF only!
Description
The SMPS180 Power Supply module is a high efficiency switch mode power supply specially designed to be used in combination with our range of UcD™ amplifier modules. Key features are high
efficiency over the entire load range, universal input voltage range (100 – 250V 50/60Hz), near unity Power Factor, low weight and very low radiated and conducted EMI. The SMPS180 also features an advanced overcurrent protection which in case of temporary overload simply reduces the output voltage, only when the overload condition remains for a longer time the supply will enter hiccup mode until the overload condition disappears. This feature in combination with the advanced feedback topology and large secondary buffer elcaps leads to the capability of delivering high peak power to the connected amplifier. The SMPS180 includes also an auxiliary isolated ±12V supply and a control circuit directly interfacing with our range of UcD™ amplifier modules. Further the SMPS can be on-off controlled from the secondary side or put in a latched off condition in case of serious fault conditions on the secondary side load. Great care has been taken to optimise the power stage and magnetics in order to achieve lowest EMI signature possible.
We are happy with the sonic result so far, we leave it to the customers to judge how good it's compared to other SMPS what are also special designed for audio amplifiers.

Jan-Peter

I think many would like to know what difference can you hear compared against your analog power supplies based on the parts you supply.Jan-Peter said:Hi,

I had my eyes on this and wonder if the voltag can be lowered by the user.

Yes, you can reduce the voltage, range will be 2x35V to 2x45V.
