## Description

750Va Usb And Serial 120V

Review: Pellet Stove Backup Power Supply - I originally bought the APC Back-UPS XS BX1000G 1000VA Tower UPS ($125) to protect and provide emergency power for our pellet stove. Once I got it I determined with APC Tech Support help it would not be good for this purpose. So they recommended this one instead because it can handle AC Motor loads and does not change the sinewave that can damage AC Motors. This one though is a great deal more expensive and heavier. However I watched for a "Warehouse Deal" and got this for only $160.00 almost 1/2 of retail plus it included shipping. Hooked it up and it works perfect, "plug and play". For those that do not know - a pellet stove requires an exhaust fan to run in order to extract smoke to the outside. If your pellet stove is in the burn cycle and the power goes out, chances are smoke will backup in to the house. With this connected it works flawlessly and allows me to shut down the stove and not have any smoke problems. If the power outage is short term it can run the pellet stove for about 40 minutes without AC Power. There are specific systems out there that will run much longer but they are 4-5 times the money and will not power the auto igniter. With this one you don't even know it switched over... I would highly recommend it. Also if you are in a place with long term power outages you can use a generator to provide constant power to the UPS which in turn will smooth out the current and provide exactly what the stove needs. Generators have such a fluctuating current and voltage they can damage the electronics in a pellet stove (as well as any other sensitive electronics). This stops damage from happening. Also on a side note - for one money we now have our computers protected and will be protecting our TV and related electronics as well.... all around a great piece of equipment for little money!
Review: Great UPS that works when I run my generator. - I live in the sticks so not only do I have wobbly utility power, but I am often on my generator which seems to confuse the heck out of so many UPS's. This APC works great at evening out my power in both states and doesn't just switch to pure battery when I am running the generator. I am slowly replacing all of the units in my house with these models and have also had great luck with getting refurb units.

## Questions & Answers

**Q: Are the output power ratings peak, or continuous?**
A: Continuous, battery limited.

**Q: What are the permissable operating temperatures for the device?   Can it be used in an unconditioned (hvac) warehouse environment?**
A: So I know the original asker has moved on by now, but this is a top question.

Lead-acid batteries don't like to be over 30C.  Supposedly, every degree over 30 halves the battery life.

**Q: Will this unit work with a home sump pump?**
A: No. You would be better to purchase a second, battery-operated sump pump or a small generator.

**Q: Would it work in UK?**
A: No, This is 120V UPS and only work with 120V outlet.
European model will be SMT750i

### ⭐ Caught Fire after 6 weeks!
*by S***E on January 2, 2012*

About two hours before leaving for a long holiday weekend, this UPS started sparking. We rushed it out of the building and it burst into flames! I cannot imagine what would have happened had no one been here. After the fire burned itself out, we plugged it in again to see if the problem would continue. Sure enough, the sparks started flying and the flames came back. Unbelievable! Goes to show it would have just kept burning worse and worse if we hadn't been there to get it out of the office. APC came a couple hours away from burning down our office building. When we called to report the problem, they couldn't care less. They offered to send a replacement (how could we trust it?!) and weren't even interesting in getting the unit back to see what went wrong. They did tell us if we wanted to send it back, we could, at our cost. Always thought APC was a leader in the UPS industry. Now we're replacing all their products.
