PRODUCT OVERVIEW

ABB PowerValue 11 RT 3 kVA B UPS

The ABB PowerValue 11 RT 3 kVA B is a true online/double‑conversion UPS designed to deliver clean, uninterrupted power for critical single‑phase IT and communication systems. With a 3 kVA / 2.7 kW rating, this model protects servers, storage devices, network equipment, and sensitive electronics from mains disturbances such as surges, sags, noise, and outages. It is engineered for both rack‑mount (2 RU) and tower configurations, giving installers flexibility in deployment.

Electrical Performance and Power Quality

This UPS uses online double‑conversion (VFI‑SS‑111) topology to continuously condition incoming mains power, delivering a pure sine‑wave output with tight voltage regulation (± 1 % referred to 230 V) and low distortion under load. The unit supports a broad input voltage range (208 / 220 / 230 / 240 VAC) and frequency tolerance (45–55 Hz / 54–66 Hz), making it tolerant of unstable utility conditions. Its output power rating of 2.7 kW (0.9 power factor) ensures efficient real‑world power delivery to connected loads.

Battery Backup and Runtime Features

The PowerValue 11 RT 3 kVA B includes built‑in valve-regulated lead‑acid (VRLA) batteries, enabling essential backup power during grid outages. Typical backup time at full rated load is approximately 4 minutes, suitable for graceful shutdowns or short interruptions; actual runtime varies with load and configuration. The unit supports external battery modules (EBMs) to scale runtime further for longer outages or critical load requirements. Recharge time to 90 % battery capacity is typically around 3 hours under normal conditions.
