Riello UPS Sentinel Pro

The Riello UPS Sentinel Pro has a unique and modern design and improved performance developed by the Riello UPS research and development team. Sentinel Pro uses on-line double conversion technology, resulting in the highest levels of reliability and maximum protection for critical loads such as servers, and IT and voice/data applications. For business continuity applications requiring long battery runtimes, battery autonomy can be extended up to several hours using ER models fitted with more powerful battery chargers. The front display panel has been entirely redesigned, adding an LCD display that shows the input and output voltages, battery readings and UPS operating status information.

Different operating modes that can be programmed according to user requirements and the load to be powered have been introduced in order to reduce energy consumption:

  • Online: maximum load protection and output voltage waveform quality
  • Economy Mode: the UPS uses line interactive technology, with the load powered by the mains, reducing consumption and thus improving efficiency (up to 98%).
  • Smart Active Mode: the UPS automatically selects on-line or line interactive operation, depending on the quality of the mains supply, checking the number, frequency and type of disturbances present.
  • Stand by Off (emergency): The UPS supplies the load only when the mains fails. The inverter begins working with a progressive start-up sequence to prevent inrush currents.
  • Frequency converter operation (50 or 60 Hz).

Suitable for:

  • Individual computers
  • Office equipment
  • Home entertainment

The Riello UPS Sentinel Pro has many advantages including: 

  • Filtered, stabilised and reliable voltage: double conversion on-line technology (VFI compliant with IEC 62040-3) with filters for the suppression of atmospheric disturbances. 
  • High overload capability (up to 150%) 
  • Programmable Auto-restart when mains is restored 
  • Battery start-up (cold start)
  • Power factor correction (UPS input power factor, close to 1) 
  • Wide input voltage tolerance range (from 140 V to 276 V) without battery intervention. 
  • Runtime extendable up to several hours 
  • Fully configurable using UPS Tools configuration software 
  • Highly reliable batteries (automatic and manually-activated battery test) 
  • High level of UPS reliability (total microprocessor control) 
  • Low impact on the mains (sinusoidal take up).
