UPS or line conditioner used?

[WeStSiDePLaYa]

im wondering if you hook the power supplies up to a UPS or a line conditioner.

im sure jonny, you have seen enough psus to know some really lack in the AC filtering department.

i was thinking a good idea would be able to provide some testing when hooked up to a UPS, and some while hooked up to a "dirty" AC line.

doing it for every psu would probably be too much work since it could greatly increase the amount of tests needed to be run.

but maybe you could create an article showing the effects of using a UPS, and the effects of "dirty" AC feed.

and then how well a few popular psu's handle the "dirty" AC. should be interesting to see how the effecieny, volt reg, and ripple is affected by "dirty" AC on some psu's.=

The PSU's are hooked up to a Weibo PF1211 AC power analyzer. The power to this goes through a Dai Yi Shing 0~260VAC variac that gets it's power from a 2000VA Powercom AVR.

Not room and no time for "dirty" AC input, although I do intend to do a round-up of cheapy PSU's where I will use the variac to drop input voltage to around 90VAC to see if the PSU blows up, trips, etc.

Not to mention jG lives in the Sunshine state:p

Theoretically switching power supply shouldn't much care about input waveform but I suspect it might be different at least with El Cheapos.

I can tell you there is a noticeable difference in the output of sound from the DC motors on my fish tanks when they are running off of the modified sinewave UPS. ;)

Non PFC power supply is one of the least pickiest electrical appliance. Active PFC can get picky with quasi-square wave.

Anything with induction motor won't run too well on non-sinewave either.

What kind of motors? We tried running those "one piece spinning magnet" motors in power heads with mixed results. Some just clatter like crazy. If you have a sump below the tank better make sure that return line has a GOOD check valve in it if it goes more than a few inches below the water line. (or ample sump capacity)

Nothing worse than a power strip soaked in salt water popping and spewing pink flames when the juice does come back. :@
