APC SRT5KRMXLW-HW 5000 VA 4500 Watts Rack-mountable UPS

[This review was collected as part of a promotion.] A certain VA uses these all the time and due to flexible options and manageability, this unit can exceed ones expectation. Great standby time, Form Factor as well as unit comes with Rails for rack mounting. Thing is a beast, but but also quite small for what it can really do

[This review was collected as part of a promotion.] I've been running this APC Smart-UPS On-Line 5.4kVA for over a year now in our small data center, and it's been absolutely fantastic. What I love most is the true online design - during power fluctuations and outages, our servers never experience even the slightest interruption, which is critical for our 24/7 operations. The 3U form factor is perfect for our space-constrained rack, giving us serious power protection without eating up valuable rack real estate like larger units would. The mix of L6-20R and L6-30R outlets perfectly matched our server and storage equipment requirements, and the extended runtime feature has saved us multiple times during longer outages - we easily get 45+ minutes of runtime with our full load. The network management card is incredibly useful for monitoring power conditions remotely and scheduling maintenance, plus the SmartSlot gives us room for future expansion options. Installation was a breeze with the included rail kit, and the unit runs quietly enough that it doesn't add noticeable noise to our server room. For the price point, you really can't beat the combination of true online protection, compact size, and enterprise-grade features - this UPS has been rock solid and gives me complete confidence in our power infrastructure!
