Dear friends,
First off all, sorry about my question if that make you boring. Not "boring" we are being safe. We do not encourage anyone to build on-line power supplies from information supplied by us. Its something even pros will sub-out to people with the experience in such things. You need to have isolated tools and instruments to work on such things for a start. This is personal safety critical stuff and not a beginners project. About the +12vdc with 400mA for Relay driver, RF modul and regulator to +5v for MCU. 6VA and the relay doesn't need to be powered off the regulated rail. The transformer for that is pretty tiny.

| No way | 01/01/70 00:00 | |
| 6 VA ? | 01/01/70 00:00 | |
| Better relay = lower current | 01/01/70 00:00 | |
| smps | 01/01/70 00:00 | |
| smps are fine if you can make them work | 01/01/70 00:00 | |
| Maybe we've missed something. | 01/01/70 00:00 | |
| probably because the OP stated "I know b | 01/01/70 00:00 | |
