The Sentinel Pro has a unique, modern design and enhanced performance created by Riello UPS's research and development team. Sentinel Pro ON LINE uses dual conversion technology to provide the highest level of reliability and maximum protection for critical workloads such as servers and IT and voice/data management applications.

For business continuity applications that require a long battery life, the battery autonomy can be extended to several hours if the ER models are equipped with more powerful battery chargers.
The front display panel has been completely redesigned and an LCD display has been added to display input and output voltages, battery readings and UPS operational status. The inverter and microprocessor control section have been completely redesigned to provide greater efficiency and greater configuration options.

Maximum expandability: The Sentinel Pro comes standard with a USB port and an expansion slot for protocol conversion or relay contact boards. With energy savings in mind, the Sentinel Pro is also equipped with a stop button that reduces energy consumption to zero for longer periods of inactivity (ECO LINE). The Sentinel Pro is available in 700 VA, 1000 VA, 1500 VA, 2200 VA and 3000 VA models.
