Riello Aros - Sentryum

The Sentryum 10-60 kVA offers the best combination of power availability, energy efficiency and global performance ensuring installation and running cost savings. It is the very latest Riello UPS development resulting in a third-generation transformer-free UPS, originally introduced into the market over twenty years ago. The Sentryum series is a transformer-free UPS available in 10-20-30-40-50-60 kVA with threephase input and output. Sentryum is designed and built using state-of-the-art technology and components. It applies the advanced technologies such as DSP (Digital Signal Processor), dual core microprocessor, three level inverter circuits and resonant control to provide maximum protection to the critical loads with no impact on downstream systems, whilst maintaining optimised energy savings. With a unique control system, it makes it possible to reduce the inverter output harmonic voltage distortion and provide rapid response to all load variations, ensuring an outstanding sinewave form during all conditions.
