APC SRV3KRI uninterruptible power supply (UPS) Double-conversion (Online) 3 kVA 2400 W 7 AC outlet(s)

Product Overview

AI-generated summary

The APC SRV3KRI is one of those “boring but dependable” online UPS units that you buy when you really don’t want to think about power quality again. Double-conversion (online) means it’s designed to protect sensitive kit from brownouts, spikes, and dodgy mains—so it’s a solid fit for servers, networking gear, and any business-critical workload where downtime costs real money. At ~£1.4k ex-VAT for a 3kVA class unit, it’s not cheap, but it’s in the reasonable bracket for an online UPS from a name you can actually get support for in the UK.

That said, I wouldn’t buy it for every small office. If you’re mostly protecting basic PCs/routers in a single room and you’re comfortable with brief transfers or you don’t have harsh power issues, a line-interactive UPS is often better value. Also, the real cost of ownership isn’t just the purchase price—if you need long runtime, batteries can become a recurring spend and replacement planning matters. Overall: great choice for SMEs and IT resellers standardising “serious protection” for server rooms, comms racks, and fibre/telecom gear; less compelling if your priority is budget protection rather than clean, continuous power.
