Riello UPS 40kVA UPS Sentryum S3T 40 ACT A0
The Sentryum S3T 40 ACT A0 is from Riello UPS's third generation of transformerless online Uninterruptible Power Supply (UPS) systems. Produced as an upgrade to the popular Riello Multi Sentry UPS, the Sentryum delivers key improvements including USB, RS232, and RJ10 ports, as well as a variety of communication card slots.
The Riello UPS Sentryum S3T 40 ACT A0 has no internal batteries, making it highly efficient and capable of delivering full-rated power (unity Power Factor). It has an astounding operating efficiency of up to 96.5% in online double mode at loads as low as 50%.
The three-phase input/output Sentryum possesses a powerful control system that reduces harmonic voltage distortion (<1% at resistive load and <1.5% at non-linear load). This provides enhanced overload and short circuit capacity to guarantee optimum availability.
The Sentryum (S3T) range is equipped with a 5-inch colour touchscreen. It also comes with an intelligent LED status indicator to ensure that you remain up to date with the current operating state of your UPS.
This product is scalable up to 8x UPS in parallel to increase capacity or build redundancy.

Reliable And Efficient
Our transformerless Sentryum S3T 40 ACT A0 UPS delivers unity power (pf 1) and operating efficiency of up to 96.5%. This helps you minimise wasted energy. It features a unique control system that reduces harmonic voltage distortion (<1% at resistive load and < 1.5% at non-linear load). The Sentryum can also handle high overloads (125% for 10 minutes or 150% for 1 minute). The system protects against short circuits (270% for 200ms or 150% for 300ms), meaning you won’t have to transfer to bypass to deal with sudden peak loads.
Scalable Power
Easily increase your power or battery autonomy by installing up to 8 Sentryum UPS in parallel (3-phase version). Parallel installations operate on a closed-loop system, so your UPS will keep running even if there’s an issue or disruption with your cable connection.
Enhanced Performance
Sentryum builds on previous Riello UPS transformerless series such as the Multi Sentry (MST), with an optimised card layout that reduces the number of components, cables, and interconnections. This reduces the amount of installation space your UPS will need and makes it far easier and more cost-effective to maintain.
Power At Your Fingertips
Take control with a 5-inch colour touchscreen display panel which clearly shows real-time information and allows you to easily adjust the operating mode. Also features an innovative new LED status indicator that automatically changes colour depending on the current operating mode and UPS status. In-built wheels enable easy manoeuvrability.
Advanced Communications
Sentryum is equipped with a coloured graphic touch screen display providing UPS information, measurements, operating states and alarms in different languages. The default screen displays the UPS status, graphical indication of the energy path through the UPS and the operational condition of the various assemblies rectifier, batteries, inverter, bypass) within the UPS.
Operating Modes
The Sentryum online UPS units include a complete range of operating modes that are controllable by users. These include:
- Smart Active
- Online
- Eco (up to 99 percent efficiency)
- Emergency (Standby Off)
- Frequency Converter
The Sentryum range of online UPS units is also compatible with sealed lead-acid (VLRA) AGM, open vent, GEL or nickel-cadmium batteries. Alternative backup sources like supercapacitors and lithium-ion batteries can also be used.
