I have a collegue that would like a definition of Hold-up time as it pertains to a power supply. It is agreed that the time should be measured at 120VAC input and full load on the output. Time starts when the AC input shuts off (preferably at the + or - peak). Here is where the question comes in. Should the hold-up time stop when the output voltage drops out of regulation, or when the output voltage drops to 75% of the regulated output? Personally, I would use 90% of regulated, but 2 of our engineers are disagreeing and both are very adament that they are correct. I hope one of our subscribers may have a verifiable answer. Thanks in advance.\
