Now available in the new sizes from 40-50-60 kVA, Sentryum S3U is a transformer-free UPS with double conversion ON LINE technology that provides high levels of power availability and energy efficiency up to 94.5%.

​

Ideal for the protection of small or medium-sized Data Centers and "mission-critical" applications, Sentryum S3U has been designed by choosing a "Green Technology" approach, with components that allow to reduce dissipation and energy losses and improve the overall energy efficiency performance.

Advanced digital PFC control together with very high frequency (19.2 kHz) NPC inverters help to mitigate the impact of the UPS on the network, reducing overall operating costs and consequently also energy costs.

Equipped with an exclusive control system that reduces the harmonic distortion of the inverter output voltage with non-linear load, Sentryum guarantees a perfectly sinusoidal three-phase voltage in all conditions.
