Reading this thread has prompted me to float another idea I had about switching my switchmode power supplies on and off remotely. From my post in that thread: Anyway, it occurred to me that if I were to make a board to do this, it might as well have more than one relay (maybe room for 4) so it could turn the switchmode power supplies on one at a time. Each one would turn on a few seconds after the previous one. This could stop them all drawing their inrush (surge) current at once and potentially tripping the house circuit breaker. Multiple relays could also be useful for where multiple power supplies are fed from separate power outlets. One of the power inputs to the board would power the first output and the on-board electronics. The other inputs and outputs would be just relay connections. Comments?
