There have been numerous times I've had to work on UPS's and I can't shut down the system. Is it possible to put a switch in line with the power input so I can switch the power over to a different source say from the UPS to the wall (or other UPS)? Would the caps in the UPS function for the few ms it takes to switch over?
I was thinking another option would be to add a larger cap in the power supply after the rectifier I guess. I would think this might give enough cushion for a switch to work.
Anyone have any thoughts?
