UPS and Power Regulation

Q: Can I run both a UPS and an AC power conditioner/surge suppressor, or should I only use one?

A: The answer to this one lies deep in the inSync Tech Tip of the Day Archives:

“If you’re using a UPS to power equipment in your studio you may be better off if you don’t also connect other sophisticated regulation and surge suppression boxes in-line. The components inside higher-quality surge suppression devices present strange reactive loads to a UPS and can cause the UPS to damage them (the UPS will rarely damage itself).

“The theory of all of this is way to deep to get into here, but suffice to say that if you have a UPS on line you shouldn’t also need a sophisticated conditioner-type unit. You are, in fact, better off without one. If you try to use one anyway you will most likely damage it. Further, the “additional” protection doesn’t show up as additional protection to the gear in question anyway. More is not better in this case. You’re simply trying to deliver good power to the devices. You don’t want to over modify it (the power). For more details you should consult the maker of your UPS.”
