Sentinel Rack UPS

Sentinel Rack

Power Range

1500 - 3000 VA
  • 1:1

Sentinel Rack is a compact single-phase rack-mount UPS for servers, IT and voice/data applications. At just 380 mm deep, it is an ideal way to upgrade shallow rack cabinets or wall-mounted cabinets where space is tight.

Available in 1500 VA and 3000 VA models, it uses on-line double conversion technology to give critical loads the highest levels of reliability and protection. Selectable operating modes, including ECO Mode, help to reduce energy consumption, and a shut-off switch cuts consumption to zero during prolonged periods of inactivity.

Where longer runtimes are needed, the SER 3000 ER model combines a powerful battery charger with external battery packs to extend autonomy to several hours. An LCD display, USB port and expansion slot come as standard, and noise is kept below 40 dBA.

Characteristics

  • Power factor 0.9
  • Operating flexibility
  • Emergency function
  • Battery optimisation
  • Runtime expandability
  • Compact design
  • Depth 380 mm

Different operating modes are available to reduce energy consumption based on specific load and user requirements.

  • ON LINE: maximum load protection and output voltage waveform quality;
  • ECO 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;
  • STANDBY OFF: 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).

This configuration ensures the operation of emergency systems that must be supplied in the event of a mains power failure, such as emergency lighting, fire detection/extinguishing systems and alarms. When the mains power supply fails, the inverter begins powering the loads with a progressive start up (Soft Start) in order to prevent overload. Sentinel Rack is compliant for installation in medium-voltage transformer rooms in accordance with applicable legislation, for the power supply with reserve charge of medium-voltage coils.

The Sentinel Rack range has a deep discharge protection device to optimise battery life. Periodically the UPS carries out a battery efficiency test (which can also be manually activated); its wide input voltage tolerance range helps to reduce battery usage and maintain performance over time.

The SER 3000 ER version is designed without internal batteries, therefore it must be combined with one or more battery packs for normal operation. Thanks to a powerful charger, it is possible to configure solutions for long periods of autonomy and recharge the batteries in a short time.

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.

  • 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).
  • Multi-platform communication for all operating systems and network environments: PowerShield3 supervision and shutdown software for Windows operating systems 11, 10, 8, Server 2022, 2019, 2016 and previous versions, Windows Server Virtualization Hyper-V, macOS, Linux, Citrix XenServer and other Unix operating systems;
  • UPS Tools configuration and customisation software supplied as standard;
  • RS232 serial port and opto-isolated contacts;
  • USB port;
  • Slot for communications boards.
