Wink using meanwell SMPS S-350 as power amp PSU?

Hi guys,

Has anyone used Meanwell SMPS for their amplifier project?

I'm helping a friend building a 150W stereo Class-D power amplifier and trying to keep the size down. The power rails needed is +/- 50-60V and the Meanwell S-350 seems like a good choice.

I'll probably add some decoupling caps at the output of S-350 and tadaa! Please share if you've any experiences on this.

only 1 supply rail? You will need 2 of these or modify them.
Kind regards,

Iv'e used the Meanwell SMPS with 41hz amp9-basic and it works very well but that has a single ended supply. Iv'e heard good results using it with the SureElectronics 2x100W as well (single ended too).
