Power for TA2022 amplifier board?

[joeoz]

Hi,

I have this TA2022 amplifier board:

YJ TA2022 90W+90W Volume contol amplifier board new | eBay

According to the description, the board requires AC 22V-0-22V 5A power, so would it be possible to use transformers that are used for halogen lights? I have a bunch of these transformers (they are AC 240V in -> 12V out, and 50W output).

If it's possible, how would I connect them together? I was wondering if I could use a pair of them to get 24V, and another pair to get the other 24V. Would that be too much for the TA2022?

I'm still a newbie at this, so any help is greatly appreciated.

Thanks,
Joe

Not unless they're completely ground separated which is highly unlikely.

I'm no expert on these things but I would say you are wasting your time with those transformers when all you need is a single 225VA toroidal transformer with 22+22V output. Expensive I know but worth it in the long run.

That's my take on it anyway.

Cheers,
Steve

They also tend to have a very low switching frequency and will inject tons of noise into the amp.

Thanks for your replies.

Other than the toroidal transformer, are there any other options fro powering this board?

Thanks!
