請問有冇高手指教，本人欲DIY發燒級外罝電源供升頻及解碼用，要求為DC12V和AC9V，各50W。
多謝幫忙！

Hi,

Could you mind provide more details?

DC 12V --> which parts ?

Firstly, thanks for your quick respond, KK Ho.
The DC12V is for the 24bit/96kHz Upsampler
The AC9V is for the DAC

SUM,

I will drawing the circuit for you.

BTW, what kind of socket (4A current)you are looking for ?

Each part is 50W, seem too higher.

12V / 4A = 48W

9V AC (5.5A) = 50W

Please confirm.

KK.

Hello KK Ho,
You're really a nice guy. Actually, 2A should be enough. Therefore, power for each group should be 30W (including safety).
The additional requirements:
Power inlet: IEC panel socket for 220VAC
Power outlets: common 2.5mm d.c. power connectors
Lastly, please also suggestion which types/brands of components (cap, resistor, connector, wire, etc) should be selected as a hi-end product.
Thanks a lot
Mr.SUM

是裕量还是输出？
