The standard battery gives you a few minutes of backup. That's fine for a graceful shutdown. It's not fine when your clinic's patient records server needs to stay up through a 40-minute substation fault, or your school's network can't afford to go dark mid-exam week.
The Centurion RT 3000VA Long Run model is built for exactly that. Same true online double conversion, same zero-transfer-time protection, same 0.9 output power factor — but designed to plug in an external battery bank (UPPS-CRTBB12) and keep your load running significantly longer.
Advanced ECO mode still hits up to 98% efficiency when the mains is stable, so you're not paying a premium to keep the unit warm. Hot-swappable internal batteries mean routine maintenance doesn't mean downtime. EPO button for the emergency. Programmable outlets let you shed non-critical loads automatically and stretch your runtime further.
RS232 and USB comms standard. SNMP, AS400, EMD, and Modbus available as optional modules if your monitoring stack needs them. Generator compatible. Rack or tower form factor.
External battery (UPPS-CRTBB12) is required for long-run operation. Built for Australian environments where extended backup isn't a luxury — it's the difference between a logged event and a full outage
