I have a couple of obscure german “AT60” power supplies I scavenged from some designer lamps. They’re small, and don’t get hot even under ~30W load — but for my purposes, I need them to be always on, or at least switch ON at a load of 0.25W. A microcontroller needs to be always on and do some things, which may bring the load up to 10-15W, by my estimates.
Any clues would be greatly appreciated. I have of course already googled and asked a ham radio operator; neither knew anything.
To clarify: I need this powersupply to either turn on at lower load, or be always on. It needs to power a microcontroller at ~0.2W, and this micro will in turn switch “things” on, up to a max load of ~15W.
