Product features

• Simplified installation
  Sentinel Dual can be installed as a tower or in 19" rack cabinets, by simply removing and rotating the mimic panel. Low noise thanks to a high frequency switching inverter and load-dependent digitally controlled ventilation.
• Installation versatility
  Sentinel Dual can be used in a tower or rack format, by simply turning the display and adding the supplied feet or optional runners.
• Emergency function
  This configuration is designed for emergency systems including lighting, fire detection/exit systems and alarms. When the mains power supply fails, the inverter begins powering the loads with a progressive start (soft start) in order to prevent overload.
• Reduced noise
  Thanks to the use of high frequency components and load-based fan speed control, the noise produced by the UPS is less than 40 dB.
