Riello STW 5000 5kVA Sentinel Tower UPS
Riello Logo
with 8 minutes autonomy



Overview Delivering more real power in a compact footprint, the Sentinel Tower (STW) series is a proven performer across a variety of applications, including blade servers, safety systems, and telecommunications networks.

Choice of 5-6-8-10 kVA power ratings, with the latter 2 suitable for use on three-phase distribution networks. Designed to deal with non-linear loads, delivers quality power (pf 1) at high efficiency (up to 95%).





Proven Performance 3-level inverter helps deliver unity output power factor (kVA = kW) and achieve up to 95% efficiency in ONLINE mode, reducing unnecessary energy waste.

Designed to handle non-linear loads like blade servers and has high short circuit and overload capacity.





Scalable Power You can parallel up to 3 STWs together to increase capacity or ensure (2+1) redundancy. Parallel installations operate on a closed loop, meaning that they carry on running even if there’s an issue with the connection cables.





Complete Control Revamped custom-designed LCD display panel shows crucial operating data, alarms, and statuses such as voltage, remaining battery, and current load. Easily adjust operating modes at the simple push of a button.





Compact Footprint Whatever the power rating, the STW measures in at a compact 25 cm by 69.8 cm by 50 cm (W x D x H), with built-in castors assisting with mobility.

Minimal noise disruption as the fan speed automatically adjusts according to the current load.





High Battery Reliability STW features automatic and manual battery testing, while the batteries don’t cut in during temporary mains failures (< 20 msec) or if the input is between 184-276V, which helps to maintain lifespan.

For applications needing several hours’ autonomy, choose extended runtime versions (6 kVA and 10 kVA models) fitted with 6A chargers and connected to external battery boxes.
