I've got a drawer full of spare power supplies for various projects. All are AC in. Most are SMPS. Most are AC/DC. A few are AC/AC. A few are stacked plate transformers.
A few of them have the plastic bodies removed.
How do I identify the AC inputs and DC outputs either visually or with a meter and without risking damage?
