The Riello UPS Sentryum is manufactured used state-of-the-art components designed to run flawlessly at temperatures up to 40 °C. These include a dual-core DSP processor and three-level inverters that operate at high frequency (18 kHz).
This ensures the S3T UPS (Uninterruptible Power Supply) delivers full-rated power (kVA = kW 1 pf) with exceptional operating efficiency of up to 96.5% in online double conversion mode.
Available as three-phase/single phase input, single-phase output or three-phase input and output, the UPS has a unique control system that reduces harmonic voltage distortion (< 1% at resistive load and < 1.5% at non-linear load).
In addition, the Riello UPS Sentryum has high overload (125% for 10 minutes, 150% for 1 minute) and short circuit (270% for 200ms and 150% for 300ms) capacity, which enables it to handle sudden peak loads without needing to transfer to bypass.
Install up to 8 S3Ts together in parallel to scale capacity or build in redundancy (i.e. N+1 configuration). Closed loop system ensures the UPSs continue to function even if there’s a disruption to the connecting cables.
A revamped 5-inch colour touchscreen display panel clearly highlights crucial UPS measurements and operating statuses. While an innovative new LED status indicator automatically changes its colour (light blue, dark blue, yellow, red) depending on the operating mode and condition of the UPS.
