High-efficiency three-phase transformerless UPS with IGBT rectifier, unity output power factor, up to 96.2% ON LINE efficiency and 99% SMART ACTIVE efficiency. Features EnergyShare sockets and advanced communications for data center and critical infrastructure protection.
The Riello Multi Sentry is a high-performance, three-phase online double-conversion UPS covering 160 to 200 kVA. Built for medium data centers and demanding industrial installations, it combines high efficiency, low input distortion, and robust overload performance in a compact footprint.
The Multi Sentry is a cost-effective choice for sites that need enterprise-grade protection without the complexity of larger modular systems.
Double-conversion protection with a wide input window ensures a perfectly clean output regardless of upstream power quality.
Advanced power electronics deliver high efficiency in both online and eco modes, reducing both energy cost and cooling load.
Generous overload capability covers motor starts, medical equipment inrush, and transformer magnetizing currents without transferring to bypass.
A graphical display, standard serial/USB, and optional SNMP/Modbus cards make monitoring and automation straightforward across IT and OT platforms.
