The Riello Sentinel Pro 3000VA Extended Runtime Uninterruptible Power Supply from Critical Power Supplies is the latest evolution of the successful Riello Dialog Plus online UPS.

Designed with the environment and efficiency in mind, the Sentinel Pro is part of the Riello ECO Line of UPS.

Sentinel Pro is an on-line double-conversion Uninterruptible Power Supply (UPS) offering the highest levels of resilience and protection for critical servers, voice and data processing IT systems.

In terms of communication, each Sentinel Pro has a built-in mimic panel with an LCD to show input and output voltages, and battery charge status. The inverter is a totally new design, fully microprocessor controlled and constructed to achieve the highest levels of operating efficiency and configuration options.

Energy Efficient
Sentinel Pro is highly efficient, and has a push-button power-off feature to reduce energy consumption to zero when there is no load connected.
