Sentryum S3M

The Sentryum S3M series provides the best combination of power availability, energy efficiency, and overall performance, resulting in lower installation and operating costs. It is the most recent Riello UPS development, resulting in a third-generation transformer-free UPS that was first introduced to the market over two decades ago. This ultimate solution has a unity output power factor (1 kVA = 1 kW) and online double conversion technology that meets VFI-SS-111 standards (as set out in standard IEC EN 62040-3). The Sentryum S3M series is a transformer-free uninterruptible power supply (UPS) with single-phase or three-phase input and single-phase output.
