The Sentryum (S3T) range is 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) Active 40kVA T4 range has a 3-minute runtime at full load. This device has no internal batteries, making it highly efficient and capable of delivering full-rated power (unity Power Factor), with 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), providing enhanced overload and short circuit capacity to guarantee optimum availability.

Equipped with a 5-inch colour touchscreen and intelligent LED status indicator, the Sentryum (S3T) range ensures 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.
