You can tell by looking at the symbols: a "~" symbol means AC, a "=" with a dashed line means DC. Uninterruptible Power Supply Questions And Answers Battery life is halved for every 10 degrees (C) temperature increase above it's specified operating temperature (usually 25 degrees (C). It is usually specified as mV per a given change of the input or as a percentage change over the whole allowed input range. Which is best: switching mode or linear?

The closer they are, the more it's possible for voltage variations on one conductor to be electrostatically induced on the other conductor (contrast to inductive coupling).Inductive couplingWhen a changing current is

Isolation: specified as the DC or AC voltage that can be applied between input and output without the supply failing.

Transient response time can be specified and is related to how long it takes the power supply to recover to a specified value after a sudden change in load or output. Most of the time, lower voltage will just make a device not work, but damage can't be ruled out unless you know something about the device. Had the author used a 20 MHz low-pass filter on the input, he wouldn't have spent time tracking down this spurious noise. Commercial Power Supply Has Voltage Regulation Of Still, the nomenclature is useful, as even the heavy, high-output power supplies have lots in common with their smaller cousins.
