Rated 1 out of 5Â by daboomer22 Bad From The Start
A recurring issue. AVR Relay Weld
An automatic voltage regulator (AVR) relay fault exists
This occurred when the unit was very new. The fix from APC was a firmware update. This worked...(maybe) until the unit was out of warranty. Now it occurs again, except this time my research indicates this will happen everytime there is low inout voltage. Unit works great for a power outage, but falls on its face for low voltage. I'm betting the issue is a hardware issue firmware cannot fix, but only mask until the unit is out of warranty

Rated 5 out of 5Â by SFX Group Works very well and has digital status display
This unit will fit both 4 post racks (cabinets) and will stand alone (as feet it can sit in), 9 I have 3 servers from this and it seems to detect all power problems even "distorted power", which is a lot better than the CyberPower units (i have sold many of both).
It runs very cool, has power grouping of outlets, an expansion slot (which i will be using the Management Card 2), this one also has the extended battery option (see below for differences).
The SMX series also has the EPO connector (Emergency Power Off) which is another button that can be bought to allow you to turn this unit off instantly if you think there might be a problem (like a fire in the servers and super storm that you donâ™t want to have issues with).
It also has a front mounted digital display that if set to "advanced" will tell you how much power is being drawn, what the reason was for the last power transfer and other details, the screen updates every 5-10 seconds.
I have a 600 deep cabinet and this unit fitted after i cut about 2inches from the fixing rail kit as it was to long (they made it fit 1000mm deep cabinets).
There are a number of these units:
SMT has no extended battery connector (and most donâ™t have the EPO connector)
SMX has the extended battery connector
There are older versions of both that do not have the digital display on the front and are lower efficiency as look more âœindustrialâ

Rated 5 out of 5Â by Vestrit Works well
The UPS functions flawlessly, just like all other APC UPS's that I have bought.
It does look different from the picture however. The one in the picture has a front cover. The one I got did not. Mine looks much more industrial.

Rated 5 out of 5Â by CBeck Good, sturdy product
Purchased 2 of these and as with any APC product, works great, sturdy, and easy to install. My only issue (which is minor) is that I wish the front bezel snapped a little more snugly, or had a release lever. It's too loose and feels like you can bump into it and it will fall off. But it won't stop me from purchasing more of these units.
