solved power supply (current) question (not a computer PSU) solved What tier is this PSU? The more efficient type is AC/DC, where the UPS delivers the DC voltages needed by the system. I would like to make this PSU current limited, or at least shut off when the current goes too high.I basically took the concept of the linear voltage regulator and expanded If I were you, I'd make an oscilloscope.

A. What is true about the breakdown voltage in a Zener diode? A 5 mA changes in Zener current produces a 50 mA change in Zener voltage. This means that the bridge diodes are pushed quite hard and drop more than the "conventional" 0.7 volts.
Are you? A. UPS batteries are designed for maximum life in 'typical' use, which means long periods at continuous low charge and occasional minor discharges.
