Server room going dark at 2am because the sub-station hiccuped again? This one keeps your gear breathing. The CyberPower Online S (A) 3000VA/2700W gives you clean, double-conversion power to eight IEC C13 outlets and one IEC C19 – enough for a small rack of switches, storage, and a couple of servers without breaking a sweat. Six 12V/9Ah cells sit inside, so you get real runtime, not a two-second grace period. USB and serial ports are there for local monitoring, and the SNMP slot (drop in an RMCARD205 when you're ready) means you can watch battery health from your ops dashboard. Rack it or stand it up – the rail kit is already in the box. Two-year advanced replacement warranty sits behind it, so if a unit packs in, you get a swap, not a six-week wait. Twelve units on the shelf now
