I work in music recording/mixing studio environments and am extremely fussy about equipment that generates noise. I'm pleased to say that after several months of continuous use, this Li-Ion APC rack unit met and possibly exceeded expectations. When in ideal conditions, the unit is literally silent. No fan noise, no hum, no buzz. The only time noise has been observed is either when the unit is charging (due to a power failure) where very minimal self-noise is inevitable, or in an under-voltage condition (117V or under) where the internal circuitry activates in order to boost the output voltage. In comparison to APC's own legacy units (ie: 2U 750VA-1500VA lead acid monsters) which I have been using for over 15 years - they had frequent noticeable cooling fan noise, and could produce undesirable self-noise when approaching maximum load. And anecdotally, I have had one or two units fail over the years and drop the load.

quick shipment, item is as described. Seller trying to do good, so give the seller a chance to correct if they make a mistake.

It was the exact battery for my unit. Slid it in, plugged the battery in, closed the case, plugged the UPS into the wall. That was it.

I have an older version of this same UPS, this one has a black background on the screen with blue letters and is much easier to read than the blue black/black letters.

Excellent.

Been waiting for a storm to submit a review. This unit maintained my internet connection during a Tornado Warning and subsequent power outage. I love it!

can not beat the price, and no charge to deliver to my door step!! fast!!


Works great. Put my computer to sleep to go out for the night, power went out, came back and had time to shut it off and then plugged my desk lamp into it to have some light for a time.

Easy to install Keeps your expensive POE switch protected from lightning strikes to outside cameras and APs



Easy setup Clean looking Easy management

- Solid connection that I do not worry about coming lose at all - Amp draw meter is extremely handy - Very long (maybe too long?) power cable - Lots of jacks - Front-facing jack is a nice bonus touch - PRICE


Killer how they display the Current.

Tons o outlets


-Easy to set up and get going. -The monitoring app on the computer is very useful -The UPS itself has a very clean look to it. -Comes with a 90 degree plug, to get behind a desk or piece of furniture.
