[QUOTE="Rob Timmerman, post: 81191, member: 172"] Re: Hey digital console users don't forget your UPS Switch mode power supplies have filter capacitors on the outputs, the same as the old iron linear power supplies. They just tend to be smaller because the frequency in question is on the order of tens of kilohertz, not 120hz. But there's no reason why a manufacturer couldn't add more storage to the output (and in fact, many SMPS units will ride through a brief power interruption). As far as power quality goes, SMPS units tend to be more tolerant of voltage fluctuations than the old iron units, but more sensitive to excessive waveform distortion (transformers tend to function as filters). I believe I addressed some of this further up the thread. [/QUOTE]
