SENTINEL DUAL 4000VA ONLINE UPS

Simplified installation
• Can be installed on the floor (tower version) or in rack mount cabinets (rack version). The display panel can be rotated.
• Low noise (<48 dBA): can be installed in any environment thanks to its high frequency switching inverter and PWM load-dependent digitally controlled fan
• External bypass option for maintenance with interruption-free switching
• Operation guaranteed up to 40°C (the components are designed for high temperatures and are thus subject to less stress at normal temperatures)
• Built-in IEC output sockets with thermal protection.

Operating mode selection
Functions can be programmed via software or manually via the front display panel.
• On line: efficiency up to 95%
• Eco Mode: to increase efficiency (up to to 98%), allows for the selection of Line Interactive technology (VI) to power low priority loads from the mains supply
• Smart Active: the UPS automatically decides upon the operating mode (VI or VFI) based on the quality of the mains power supply
• Emergency: the UPS can be selected to function only when the mains power supply fails (emergency only mode).
• Frequency converter operation (50 or 60 Hz).

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.

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.

10 A configurable IEC output sockets allow for runtime optimisation by programming the switching off of low priority loads on mains failure; alternatively, emergency loads that are normally not powered when mains is
present can be activated.

Advanced communications
• Advanced multi-platform communications for all operating systems and network environments: PowerShield 3 monitoring and shutdown software for Windows operating systems 10, 8, 7, Hyper-V, 2019, 2016, 2012, and previous versions, Mac OS X, Linux, VMWare ESXi, Citrix XenServer and other Unix operating systems
• Plug and play function
• USB port
• RS232 serial port
• Slot for installation of communications boards.

Unity Power Factor
• More power delivered
• More real output power (W)
Up to 3 Sentinel Duals can be operated in parallel in either capacity or N+1 redundant configuration offering increased reliability for critical system. The Sentinel Dual can be installed as Tower (floor standing) or Rack, ideal for network and server rack applications.
