Biggist "Plugin" UPS Available!
on September 14, 2017

from Nashville, TN, USA
Certainly for SRT units, at the minimum. Above this model, most UPSes are hard-wired. Dual Conversion topology and a color backlighted LCD display make this UPS very hard to beat! One of my favorite 208V UPSes.
I would recommend this to a friend!

I have 2 of these SRT5KRMXLT
on September 6, 2022
Posted by: mikeinnyc

My equipment is an extension of me so I want to protect it! My Hybrid Cloud setup is perfect for my cluster of Nodes. I had to purchase separate 120 Volt step DOWN transformer(s) for all of my server equipment. That was a better fit for my needs. Only my D3284 had a 208 Volt plug which plugged directly in the back of the APC. The rest of the Server nodes are 120v plugs which plugged into the step down transformer and the transformer plugged into the APC.
Living in NYC the power grid from Con Ed has become scary like the crime and similar to a third world power provider. Some serious Voltage drops have occurred regularly all the way down to 108 Volts which burns up equipment with higher amps. Basically, since Volts X Amps = Watts when the voltage drops like it does then the amps ramp up. Sizzle Sizzle, and bye bye equipment. We had times where the power went off and on quickly like a kid on the light switch.
Since my goal was to protect my equipment. I believe I may need an external battery pack but put it off because I built a "Generator Quiet Box for Emergency Power," so I need maybe 5 minutes of lead time that's it!
I wrote a simple script that will Call me on the phone, Text me, Email me, and even have a red flashing siren when the power fails. What I really value is that the APC unit has dry contacts whereas I setup a "Normally closed setup to my smoke detectors." If the temperature rises rapidly to 170F/ or smoke inside my APC 42U then the apc will automatically shut off all the power and the smoke detector will signal a traveler to my other smokes. I also have a clean agent setup a must have for the ultimate fire detection and prevention. In addition, I have netbotz with multiple temp sensors total overkill buy hey that's me.
Pros: the APC is it takes a beating and keeps going
handles dirty power of CON Ed and the little kid flipping the power switch off and on daily.
Negative: lead Acid does not last long but it is much safer to use than anything out there today. You bet I researched this. LIP is the next best thing.
Pros: Energy Efficient, Easy to Perform Maintenance, Ease of Management, High Quality, High Confidence Level in 24/7 Uptime
I would recommend this to a friend!

Worst ever interface for configuring notifications
on August 29, 2019
Posted by: BrentD
from Canada
For the quality and reputation of the hardware you think they'd put some effort into making it manageable. I can't say enough about how difficult and time consuming this product is to manage notifications on.
Pros: High Quality, High Confidence Level in 24/7 Uptime
Cons: Difficult to Use, Difficult Management, Lacking Vendor Support
No, I would not recommend this to a friend.

Six months ago we replaced some aging UPSs in our server room with new APC SRT5KVA units in a redundant configuration. Today we had a power failure. The units operated as designed. If the lights hadn't gone out, we may not have even noticed.

Easiest Large UPS to Install!
on May 30, 2018
Posted by: esstek
from Nashville, TN, USA
Due to this UPS having a fairly standard NEMA L6-30P, “Twist Lock” input plug and a corresponding 30A, two pole upstream circuit breaker requirement, it is a breeze to install and configure. No pesky, hard wired inputs here! I’m not sure if anything which weighs 125 lb can be referred to as “portable”, but this input connector sure makes it easier to move and reconfigure the UPS, if needed. Double conversion topology, too!
I would recommend this to a friend!
