Hi, I have a APC Smart UPS 3000, similar to the one shown in video #504 - UPS Tutorial and Teardown. Thank you for that video. My unit is rated for 208V operation, however, being in the US, the electric service to my home is 120/240 V. So, when I use this UPS, AVR/Voltage Trim is always on. My question is will this degrade the service life of either the batteries or the UPS itself? What is seems to be doing, per PowerChute software, is reducing the input voltage from 244.8V to 217.4V on the output.
Watching the video, which is excellent, it sounds like this UPS is designed to run off the mains/utility power mostly, and will only switch to using the transformers when there is an under or over-voltage situation which in my case, is constant. And hence my question of reliability.
Thank you!
Yes, I think the unit was designed for datacenter use where they have 3 phase. Since I am using it in a regular house, I only have 120/240. The exterior of the unit does not have any voltage selector and neither does the control software. I have contacted APC, but I got the general/standard "if it's not meant for 240V, then it will wear out the unit." So, I'm just trying to figure out if that is technically true. The unit in video #504 is almost identical to mine and so I figured I'd ask here...

Thanks everyone. The load will be very light relative to the 3000 VA capacity, so knowing that helps to prolong the life is great info. The batteries are $150 per set so I’d hate to keep having to replace them.
On the serial commands, that’s also super helpful info although I am having a hard time connecting using Putty on a Windows box.
Thanks you!
