Soon I will be living in a travel trailer with electricity supplied by a generator. I have been told that I need a UPS to use in conjunction with my computer type sewing machine.

The only requirement stated in my machine manual is:
"The machine is desinged for a mains supply with a nominal voltage of +/-10% and a rated frequency of +/- 4%"

Can someone tell me what I requirements I need to look for in a UPS to support this machine.

Thanks in advance.

I'm certainly no computer expert, but I have everything to do with my computer plugged into an UPS. It should do two things. A. Provide a battery back-up for Uninterrupted Power Source, so that you have time to properly turn off whatever is plugged into it, whenever you lose power, and B. provide surge protection for lightning strikes, etc. I have an American Power Conversion (APC) UPS. Try www.apcc.com or 1-800-800-4APC for more information about their products. Good Luck!

*** APC brand is your best bet, get one that will give you at least 30 minutes of backup power. This should give you enough time to get shut down and not lose any un-saved info. Not only will it give you backup power but will "condition" the 110 vac input/power and computer won't have lines in it etc.***

You need a power conditioner type UPS,
which powers your computer or whatever
from the battery, whilst charging the battery also. The cheaper ones are SPS, and supply the line power to your load, until the line
drops below a certain voltage, then it switches to battery power.

You must buy a UPS that is rated for enought watts to carry the load of your sewing machine. The more watts, the more you pay.
Find how many watts the sewing machine needs; lets say 1000 watts, then buy a UPS that is rated to handle 1000 watts. Often a UPS named 'MODEL 650' will only handle 300 watts, so read the fine print on the UPS before you buy. UPS's sizes start at about 300 watts for $80 and provide about 10 min of power. They increase in watts and run-time and you pay more money for larger numbers. Also, a UPS has a battery, similar to a car battery. It will die some day and you will have to replace it, or the complete UPS. Keep that in mind when you are considering buying an oversized UPS.
By the way, not all gas powered generators provide electricity that will operate some sensitive electronics. I think most newer models generators will work, because mine does.
