Re: Hey digital console users don't forget your UPS
Huge misconception..
the electronics that the newer power supplies are "full of" are there because the power supply is constantly adjusting its operation to ensure a consistent output voltage. That means that if there is a brief spike or dip the supply will automatically adjust (and it can react WAY faster than you can blink)
Spikes that would normally have to be absorbed by filter capacitors or sags that would have to be made up by draining the caps (in linear power supplies) are actively compensated for.
In fact, at one of my previous jobs designing and testing switching power supplies we actually had a jig that would toggle the input voltage of the supply.
we would run some of the converters off two supplies set to min and max allowable input voltages and use a function generator to toggle back and forth at anywhere from 1-30hz.
When we did so, there was a maximum allowable ripple spec for the output voltage. and that was usually a very tame ripple compared to what a linear supply would do under similar circumstances.
