APC SRV3KRIRK uninterruptible power supply (UPS) Double-conversion (Online) 3 kVA 2400 W

Product Overview

AI-generated summary

The APC SRV3KRIRK is the kind of UPS you buy when “it’s fine, until it isn’t” isn’t good enough. Double-conversion/online units are built for cleaner, more reliable power delivery than line-interactive models, so if you’ve got sensitive IT (servers, storage, networking gear) or you’re in an office with sketchy supply/voltage dips, it’s a sensible choice. At £959.53 ex-VAT it’s not cheap, but it’s also not priced like a luxury enterprise system—this feels like a solid mid-market option for a small site or departmental rack where downtime really hurts.

That said, I wouldn’t buy it just because it’s APC or because it says “online.” If your loads are modest and you mostly want basic protection from short outages, you may get better value with a cheaper UPS—online is great, but it typically costs more upfront and can cost a bit more to run. Also, make sure the capacity suits your actual power draw and consider runtime expectations (UPS sizing is where people get burned). Who this is for: UK B2B environments with real equipment risk, where you’d rather pay now than troubleshoot later. Who it’s not: someone protecting a couple of small workstations or expecting long runtimes without checking battery/runtime requirements first.
