Default SMPS Q

I was thinking of getting the ClassD Audio sds 254 or sds 258 amps.

Which SMPS PS would you recommend to get the best performance?

Also do you have noise specs, ripple etc for your SMPS?

Thanks

Cristi is resolving this for me - there was a problem with my order. Looking forward to getting this unit installed in my 1U case.

Alas, I fried my old TK2050 amp. Should have been more careful. I'm waiting for a replacement from Hifimediy - the new T1 with the sta510a chip. I'll post in the Hifimediy TK2050 thread when it's up and running.

The most suitable power supply is SMPS500R. the output voltage can be set to the value which you need. being soft-switched, the radiated and conducted noise is much lower than for a similar power hard-switched smps. output voltage ripple is below 100mV for +-60V version. note that a good linear regulated power supply have similar value. an unregulated one, bridge+transformer has few V up to 10+ V ripple.

Hi
worked through the thread but was not able to find any spec on line and load regulation ???

I'm especially interested in the SMPS500R 48V / single out version.
