Sentinel Power

On-line Double-conversion Single Phase Uninterruptible Power Supply 700VA – 3000VA

Sentinel Pro (SEP) provides maximum online UPS protection to your critical servers, data processing IT systems and telecoms networks. Single-phase UPS guarantees high-quality power (0.99 pf). Easily handles a wide range of input voltages (140-276V) and has a high overload capacity (150%). Compact design and fuss-free installation make it a great choice for protecting Edge applications.

Battery Extension Packs for Long Runtime Applications – ER Models

The ER model UPSs fitted with upgraded battery chargers are the solution for Business Continuity applications which require long battery-powered operating times. For these versions, the batteries are housed in separate cabinets which are designed to contain large, high-capacity batteries.

Fully Controllable & Monitorable UPS

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.

Work In Peace And Quiet

Sophisticated real-time controls automatically adjust the fan speed according to the current load. This ensures the noise generated from the UPS remains below 40 dBA, meaning you can work in peace with minimal distraction.
