SMPS for audio

May 21, 2008 5 Replies

Hi,


Does anyone know a good source for SMPS's for audio equipment? That would be + and - 15 volts and 5 volts for the digital stuff.



Most off the shelf SMPS's can do 5 volts but other taps are usually 12 or



15volts for drives etc. Sometimes I see one with +15 volts at 3 amps or whatever and -15 volts at a few hundred mlliamps. Not really what I want.


Cheers,


Gareth.


Anyone remember the make + model of those Pioneer/JVC/Panasonic ? tuner amps with the self contained tank-screened SMPS of about 200W. About 20 closure screws with RF mesh seals but on the other hand Yamaha Stagepas amps have minimal screening around the SMPS and none around the class D amps

Jaycar Electronics (and others probably) do a kit which produces +/-15v from a wide input range. Although it doesn't say how much current.

However, for audio unless you are pretty experienced I'd stick to analogue supplies. The hash from an SMPS can be difficult to get rid of - even if you can't hear it.

Yes I know SMPS are not the quietest, but PSU's for some audio equipment (eg EMU sound modules) are not available, and there is no room inside for a linear supply, so a replacement is the only option. Can you find one in the UK? Can you bol***s. Unless of course you know different .....

I need a 5 volt and a proper +-15 volt supply in one box. I haven't yet found one. If you can, I'll give you a peanut.

Hi,

Have you looked at Cosel

They have power supplies with capacities ranging from 200W to 720W and output modules which plug in, giving you +/- 15V and 5V at many amps.

Enjoy! James
