we have over thirty mass specs up here in Montreal (SCIEXS and LCQS). We are using Toshiba UPS's. After evalution of various systems, these were our prefered choices. They are more expensive than the average ups, but are worth it. No off-line switching on power failure (always on line current with no msec interruption (absolutely no interruption), absolutely no current flux. The best MTBF rating (mean time before failure). You have 110, 220- same box. Take a look at Toshiba. Our contact up here is ON Power systems, 1-800-290-3292 (they have many offices, including Maryland). Tell them I sent you.

Ioannis,
What, no power backup? Why not take care of the voltage with a UPS? We
use a Best Power (http://bestpower.net) 7KVA/5KW FERRUPS UPS system to boost from 208V to 120V/240V. It also takes care of the voltage sages on hot summer days (the incoming voltage once dropped to 185V here). As a side note, 208V coming into the building is 230V minus 10%, but it is very common for the outlets in most labs to be around 200-205V.

Subj: Booster transformers for LCQ

I have a question for those in the U.S. who have Finnigan LCQ ion traps: The
LCQ preinstallation guide for LCQ specifies single phase 230 V ac (+ or - 10%). Since our building (and, I suspect, most buildings) can supply nominal 208 V ac, a booster transformer is needed. I would appreciate information from people who have bought such transformers with specifics, i.e. manufacturer, model #, contact information. Thanks.
