Hi Bob, It will be on 24/7 but this was the first test on a lab-psu. I have about 50 wall contacts. About 10 are 24/7 on, they feed my guildline cabinet, timestandard ect ( there is also an UPS in between). When I leave my lab all other contacts are switched off at once for safety. So if I wanted to let it powered I had to do a lot of work to put the psu on a permanent contact ( the psu is under pile of other gear and the mains wires are all behind the shelfs. The permanent contacts are not near the bench. All ovenised and other 24/7 powered stuff is in one corner.
