Riello UPS Sentinel Dual 1.5KVA SDH (SDH 1500)
Sentinel Dual (SDU) is a doubly-versatile UPS providing maximum protection to critical loads found in server rooms, electro-medical devices, IT networks and industrial applications. Install as a 3U rackmount UPS or freestanding tower.
Sentinel Dual is the best solution for powering mission critical applications and electro-medical devices requiring maximum power reliability. 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 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.
The Sentinel Dual range is available in 5-6-8-10 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 loadâ€™s immunity to mains disturbances and lightning strikes.
Technology and performance: selectable Economy Mode and Smart Active Mode functions.
Diagnostics: Standard digital display, RS232 and USB interfaces with PowerShield3 software downloadable, communications slot for connectivity accessories.
â€¢ Â Can be installed on the floor (towerÂ version) or in rack mount cabinets (rackÂ version). The display panel can be rotatedÂ (using the key supplied
â€¢ Â Low noise (<48Â dBA): can be installedÂ in any environment thanks to its highÂ frequency switching inverter and PWMÂ load-dependent digitally controlled fan
â€¢ Â External bypass optionÂ for maintenanceÂ with interruption-free switching
â€¢ Â Operation guaranteed up to 40Â°C (theÂ components are designed for highÂ temperatures and are thus subject to lessÂ stress at normal temperatures)
â€¢ Â Built-in IEC output sockets with thermalÂ protection.
Operating mode selection
Functions can be programmed via softwareÂ or manually via the front display panel.
â€¢ Â On line: efficiency up to 95%
â€¢ Â Eco Mode: to increase efficiency (up toÂ to 98%), allows for the selection of LineÂ Interactive technology (VI) to power lowÂ priority loads from the mains supply
â€¢ Â Smart Active: the UPS automaticallyÂ decides upon the operating mode (VI orÂ VFI) based on the quality of the mainsÂ power supply
â€¢ Â Emergency: the UPS can be selectedÂ to function only when the mains powerÂ supply fails (emergency only mode).
â€¢ Â Frequency converter operation (50 orÂ 60 Hz).
High quality output voltage
â€¢ Â Even with non-linear loads (IT loads with aÂ crest factor of up to 3:1)
â€¢ Â High short circuit current on bypass
â€¢ Â High overload capacity: 150% by inverterÂ (even with mains failure)
â€¢ Â Filtered, stabilised and reliable voltageÂ (double conversion on-line technologyÂ (VFI compliant with EN62040-3), withÂ filters for the suppression of atmosphericÂ disturbances.
â€¢ Â Power factor correction: UPS input powerÂ factor close to 1 and sinusoidal currentÂ uptake.
High battery reliability
â€¢ Â Automatic and manual battery test
â€¢ Â Reduced ripple component (detrimentalÂ to the batteries) using a low ripple currentÂ discharge (LCRD) system
â€¢ Â Batteries are user replaceable withoutÂ switching off equipment and withoutÂ interruption to the load (Hot Swap)
â€¢ Â Unlimited extendible runtime usingÂ matching Battery Boxes
â€¢ Â The batteries do not cut in during mainsÂ failures of <20 ms (high hold up time) orÂ when the input supply is between 184 V toÂ 276 V.
This configuration ensures the operationÂ of those emergency systems that requireÂ continuous, reliable and long-lasting powerÂ supply in the event of a mains power failure,Â such as emergency lighting, fire detection/extinguishing systems and alarms. When theÂ mains power supply fails, the inverter beginsÂ powering the loads with a progressive start-up (Soft Start) in order to prevent overload.
The wide input voltage range and a highÂ hold-up time minimise battery usage andÂ 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 allowÂ for runtime optimisation by programmingÂ the switching off of low priority loads onÂ mains failure; alternatively, emergency loadsÂ that are normally not powered when mains is
present can be activated.
â€¢ Â Selectable output voltage (220-230-240 V)
â€¢ Â Dual input supplies configuration (SDUÂ 10000 DI and SDU 10000 DI ER)
â€¢ Â Auto-restart when mains power is restoredÂ (programmable via software)
â€¢ Â Bypass on: when the machine is switchedÂ off, it automatically goes into bypass andÂ battery charge mode
â€¢ Â Minimum load switch-off
â€¢ Â Low battery warning
â€¢ Â Start-up delay
â€¢ Â Total microprocessor and DSP control
â€¢ Â Automatic bypass without interruption
â€¢ Â Use of custom power modules
â€¢ Â Status, measurements and alarmsÂ available on standard backlit display
â€¢ Â UPS digital updating (flash upgradeable)
â€¢ Â Output sockets protected with resettableÂ thermal switch
â€¢ Â Back-feed protection standard: to preventÂ energy from being fed back to the network
â€¢ Â Manual switching to bypass.
â€¢ Â Advanced multi-platform communicationsÂ for all operating systems and networkÂ environments: PowerShield 3 Â monitoringÂ and shutdown software for WindowsÂ operating systems 10, 8, 7, Hyper-V, 2016, 2012, and previous versions, Mac OS X,Â Linux, VMWare ESXi, Citrix XenServer andÂ other Unix operating systems
â€¢ Â Plug and play function
â€¢ Â USB port
â€¢ Â RS232 serial port
â€¢ Â Slot for installation of communicationsÂ boards.
Unity Power Factor
â€¢ Â More power delivered
â€¢ Â More real output power (W)
