Sentinel Pro UPS systems are built on true online double conversion technology, which continuously isolates the connected load from the mains supply. This ensures complete protection against voltage fluctuations, overvoltage, frequency variations and electrical noise, delivering consistently high power quality to sensitive equipment.
Sentinel Pro 2 – the new generation of Sentinel Pro online UPS
Sentinel Pro 2 represents a completely redesigned evolution of the successful Sentinel Pro family. During development, Riello UPS engineers focused on the increasing demands of modern IT and industrial environments: higher efficiency, the highest possible output power factor, compact design and advanced communication capabilities.
The Sentinel Pro 2 online double conversion architecture, classified as VFI-SS-11 according to IEC 62040-3, guarantees maximum power quality and continuous availability under all operating conditions.
Why choose Sentinel Pro 2 over Sentinel Pro?
Output power factor 1
One of the key advantages of Sentinel Pro 2 is its output power factor of 1, meaning that the full nominal VA rating is available as active power. This is particularly important for modern servers and power supplies equipped with active power factor correction (PFC), allowing optimal utilization without oversizing.
Higher energy efficiency
Thanks to advanced power electronics, Sentinel Pro 2 achieves up to 93.7% efficiency in online mode, while efficiency can reach 98% in energy-saving operating modes. This results in reduced operating costs, lower heat dissipation and improved overall system efficiency.
EnergyShare – intelligent load management
The EnergyShare output sockets of Sentinel Pro 2 allow non-critical loads to be automatically disconnected during battery operation. This intelligent load management feature helps extend backup time for critical equipment and improves overall system availability.
Applications – Sentinel Pro and Sentinel Pro 2
Sentinel Pro and Sentinel Pro 2 uninterruptible power supplies are ideal solutions for a wide range of applications, including:
- IT servers and network equipment
- Corporate and industrial control systems
- Medical and diagnostic devices
- Emergency lighting and alarm systems
- Industrial monitoring and supervision systems
Sentinel Pro 2 is particularly recommended for environments where high energy efficiency, full power availability and advanced network monitoring are essential requirements.
100% Italian design – quality that delivers long-term value
Both Sentinel Pro and Sentinel Pro 2 are developed at the Riello UPS engineering center in Italy. Sentinel Pro 2 is entirely designed in Italy, ensuring European manufacturing quality, long-term spare parts availability and stable manufacturer support.
This Italian engineering heritage represents a tangible advantage for corporate, industrial and institutional users, where reliability and lifecycle value are critical decision factors.
Sentinel Pro 2 and NetMan 208 – professional network monitoring
Sentinel Pro 2 is fully compatible with the NetMan 208 communication card, enabling comprehensive network integration of the uninterruptible power supply. With NetMan 208, Sentinel Pro 2 can be seamlessly integrated into corporate IT monitoring systems, supporting SNMP protocols, automated server shutdown and advanced alarm management.
This transforms Sentinel Pro 2 from a standalone UPS into an integral part of the overall power management and monitoring infrastructure.
Conclusion – Sentinel Pro 2: the future-ready evolution of a proven concept
For many years, the Riello Sentinel Pro family set the benchmark in the compact online double conversion UPS category. Its technical concept, operational reliability and Italian engineering ensured dependable protection across countless IT, industrial and security applications.
Today, Sentinel Pro is no longer available, and its role within the Riello UPS product portfolio has been fully taken over by Sentinel Pro 2. This transition is not merely a model replacement, but a deliberate generational shift that builds on the experience of Sentinel Pro while delivering a solution that is more efficient, more capable and better aligned with long-term operational requirements.
Sentinel Pro 2 uninterruptible power supplies retain all the strengths that made Sentinel Pro successful:
– true online double conversion technology,
– excellent output voltage quality,
– wide input voltage tolerance,
– high reliability for critical loads.
At the same time, Sentinel Pro 2 introduces key enhancements that meet today’s and tomorrow’s challenges. The output power factor of 1, increased efficiency, intelligent EnergyShare load management, advanced communication options and compatibility with the NetMan 208 network card ensure that Sentinel Pro 2 is not just a UPS, but an active component of a modern power continuity and monitoring system.
It is also important to emphasize that Sentinel Pro 2 is 100% designed in Italy. This guarantees mature engineering solutions, European quality standards, long-term spare parts availability and strong manufacturer support—factors that are decisive in enterprise, industrial and institutional environments.
Based on the professional experience of Energom Electronic Kft., Sentinel Pro 2 is the ideal choice both for users upgrading from legacy Sentinel Pro systems and for those seeking a reliable, high-efficiency online UPS solution for new installations.
Today, Sentinel Pro 2 not only carries forward the legacy of Sentinel Pro, but also sets a new benchmark in the compact online uninterruptible power supply category, fully prepared to meet the critical power challenges of the present and the future.
