Yeah, I found that out. One of my UPSs crapped out after a power failure |
20 |
a couple weeks ago, then I realized it's from 2006... |

I did some looking around (I had an APC) and all the APC branded crap |
23 |
you get in the stores are cheaper, inferior options. I found out the |
24 |
BX-prefixed models don't even have proper AVR (they only correct when |
25 |
the voltage drops below a certain point, they don't do anything in an |
26 |
overvoltage situation. The BR-prefixed models are like the old UPS of |
27 |
lore, they offer true AVR for both undervolt and overvolt situations, |
28 |
and the one I have even has an option for an extra battery pack for |
29 |
extended runtime (BR1500G.) |

|
31 |
Basically anything in Best Buy, Staples, or similar stores is guaranteed |
32 |
to have the consumer BX model junk. |
33 |
|
34 |
APC gave me a reseller that sold me the BR1500G model and it was about |
35 |
$50 more. |
36 |
|
37 |
And as a bonus, it still works with apcupsd. I heard some newer APC |
38 |
models are using some new proprietary communication protocols. Never |
39 |
seen one in practice though, I wonder if that's the consumer junk I was |
40 |
reading about. |
