The product is a transformer-free UPS system with three-phase input and output and offers the best combination of power availability, energy efficiency and global performance, ensuring savings in installation and management costs. It is available in sizes 10-20-30 kVA.
With this certification, Riello UPS highlights the ability to meet the expectations of a global market and the strict specifications for protecting power supply in mission critical applications.
Sentryum S3U is designed and built using state-of-the-art technology and components: as the DSP digital signal processor optimized to perform digital signal processing, dual core microprocessor, three-level circuits and resonant control to provide maximum protection for critical loads without impact on downstream systems, while maintaining optimized energy savings.
It is equipped with an exclusive control system that allows to reduce the harmonic distortion of the inverter output voltage with non-linear load and to provide a rapid response to all load variations, guaranteeing an exceptional sinusoidal shape in all conditions.
Riello UPS offers Sentryum S3U in two different models: with or without separate bypass. Both models have been designed to offer full power up to an ambient temperature of 40 °C.
Sentryum S3U is a UPS with ON LINE double conversion technology that provides a high level of energy availability and energy efficiency up to 95.5%, with optimal performance for any small or medium sized Data Centre and mission critical applications. Riello UPS's advanced digital PFC control together with high frequency (18 kHz) NPC inverters contribute to mitigating the impact of the UPS on the network and reducing overall operating costs, not least optimizing energy costs.
