Sentinel Power

On-line Double-conversion AC UPS 700VA – 3000VA

SENTINEL PRO is the latest evolution of the successful Riello Dialog Plus online UPS. This latest development has been designed with the environment in mind and is part of the Riello ECO Line of UPS. For long runtime applications, Sentinel Pro (ER models) can be fitted with matching battery extension packs which also include additional battery boost chargers.

The UPS is highly efficient. SENTINEL PRO is designed to save energy and has a power-off push-button feature to reduce energy consumption to zero, when no load is connected or switched off. Sentinel Pro models include 700VA, 1000VA, 1500VA, 2200VA and 3000VA.

In terms of communications, 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. SENTINEL PRO UPS also have USB communication ports as standard, with a built-in expansion slot for additional adapters, protocol converters and relate contact cards.


  •  Filtered, stabilised, reliable output voltage: on-line double-conversion technology (VFI in accordance with IEC 62040-3) with built-in EMI filters
  • High overload capability up to 150%
  • Programmable auto-restart when mains power returns
  • Programmable cold-start from battery
  • Power factor correction (UPS input power factor close to 1)
  • Wide input voltage tolerance (from 120-280Vac) without battery usage
  • Possibility to extend autonomy for several hours
  • Fully configurable using UPS Tools configuration software
  • High level of battery reliability (automatic and manually-activated battery tests)
  • High level of UPS reliability (total microprocessor control)
  • Low impact on the mains (sinusoidal absorption)
  • Input protection with fuse which can be reset.

Advanced Communication

  • Advanced communication, multiplatform, for all operating systems and network environments, Powershield3 supervision and shut-down software included for Windows 7, 2008, Vista, 2003, XP, Linux, Mac OS X, Sun Solaris and VMware ESX operating systems and other Unix operating systems
  • UPS Tools configuration and personalisation software supplied as standard
  • RS232 serial port and opto-isolated contacts
  • USB port
  • Slot for communication cards.
  • Input protection with fuse which can be reset.

Runtime Expandability 

Optional battery extension packs can be connected to increase UPS runtime. In addition, the Sentinel Pro range includes
ER versions with no internal batteries and more powerful battery chargers for longer runtimes.

Low Noise Level

Thanks to the use of high-frequency components and load-based fan speed control, the noise produced by the UPS is less than 40 dBA.
