I have seen the specs for input current for various power supplies.
Obviously, the higher the maximum output current, the higher the
rated input current.
I would like to buy a power supply that is about double the usual
capacity that I will need, but I am wondering how this choice
might affect the UPS up time when the street power fails?
If the load for two power supplies is the same, will the input current
be similar if the maximum output rating of one power supply is
double the other power supply, assuming that the load is within
the rating of the smaller power supply?
Sincerely yours,
Jerome Fine
