    I’m betting on power supply. I think ACL means Alternating Current Live, and ACN is Alternating Current Neutral.

    I think the component to the very right is a transformer.

    Edit: The yellow box is a film capacitor, here is another image. The one in OP’s image is rated for high voltage. So it’s definitely taking in AC.
