Product Description

Flexibility of installation and use (digital display, user-replaceable battery set), as well as the many communication options available, makes the Sentinel Dual suitable for many different applications from IT to security. Up to 3 Sentinel Dual UPS systems can be operated in parallel in either capacity or N+1 redundant configuration offering increased reliability for critical system. The UPS can be installed as Tower (floor standing) or Rack, ideal for network and server rack applications.

The Sentinel Dual range is available in 5-6 and 8-10 kVA/kW models with on-line double conversion technology (VFI): the load is powered continuously by the inverter which supplies a sinusoidal voltage, filtered and stabilised in terms of voltage, form and frequency. In addition, the input and output filters significantly increase the load’s immunity to mains disturbances and lightning strikes.

High battery reliability
• Automatic and manual battery test • Reduced ripple component (detrimental to the batteries) using a low ripple current discharge (LCRD) system
• Batteries are user replaceable without switching off equipment and without interruption to the load (Hot Swap)
• Unlimited extendible runtime using matching Battery Boxes
• The batteries do not cut in during mains failures of <20 ms (high hold up time) or when the input supply is between 184 V to 276 V.

Emergency function
This configuration ensures the operation of those emergency systems that require continuous, reliable and long-lasting power supply 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 startup (Soft Start) in order to prevent overload.

Battery optimisation
The wide input voltage range and a high hold-up time minimise battery usage and increase efficiency and battery life; for smaller power breaks, energy is drawn from a group of appropriately-sized capacitors.
