Sentinel Dual is the new range of high-density double-conversion online UPS units, suitable for powering a wide range of devices such as servers, storage systems, VoIP telephony equipment, network and medical systems, as well as industrial applications.
It's ideal for powering and protecting Blade Server systems with a high power factor supply. The height of only 2U means SENTINEL DUAL integrates perfectly into 19-inch rack cabinets.
Appreciate Sentinel Dual for its functional, modern design, and for the performance improvements introduced through constant technological research at Riello UPS laboratories. The newly designed inverter is certainly one of the best power regeneration systems on the market, with a power factor close to 1 and 92% efficiency in On Line operation.
Easy installation:
-Sentinel Dual can be installed on the floor or in 19-inch rack cabinets simply by pulling out and rotating the control panel.
-High quietness: for installation in any environment, thanks to PWM digitally controlled ventilation that depends on the applied load and the use of a high-switching-frequency inverter.
-Features guaranteed up to 40 degrees C (components are sized for high temperatures so they undergo less stress at ordinary temperatures).
-On PREMIUM DUAL models it's also possible to program output outlets to disconnect less critical loads in the absence of mains power (energy-Share function).
Reduced management costs.
Functions are programmable from software or manually configurable from the control panel, making this UPS range very flexible and easy to use. PREMIUM DUAL can be configured in the following operating modes:
-On Line, maximum load protection and best waveform quality.
-ECO Mode, to increase efficiency (up to 98%) allows selecting Line Interactive technology.
-Smart Active, the UPS autonomously decides the operating mode based on mains quality.
-Auxiliary, the UPS can be set to operate only when mains power is absent (emergency-only mode).
-Frequency converter operation.
Sentinel Dual offers maximum flexibility for integration with any type of communication system:
-Multi-platform communication for all operating systems and network environments, Powershield monitoring and shutdown software, including for Windows 7, 2008, Vista, 2003, XP, Linux, Mac OS X, Sun Solaris, VMware ESX and other Unix operating systems.
-UPS Tools configuration and customization software included as standard.
-RS232 serial port and opto-isolated contacts.
-USB port.
-Slot for communication cards such as Modbus/Jbus, TCP/IP, SNMP and relay contact.
High output voltage quality:
-Also with distorting loads (IT loads with crest factor up to 3:1).
-High short-circuit current on bypass.
-High overload capacity: 150% of inverter (also with mains absent).
-Filtered, stabilized and reliable voltage (On Line technology with double conversion VFI according to EN62040-2 class C2 standard with filters for suppressing atmospheric disturbances).
-Low impact of the UPS on the mains: input power factor close to 1 and sinusoidal absorption.
High battery reliability:
-Automatic and manual battery testing.
-User-replaceable batteries, without stopping the unit or power to the load (Hot Swap).
-Autonomy that can be extended without limit through dedicated Battery Boxes with the same design as the UPS.
Features:
-Output voltage selectable via software
-Auto restart (automatic on mains return, programmable via software)
-Standby on Bypass: when the machine is switched off it automatically prepares for operation from bypass with batteries charging
-Shutdown for minimum load.
-Advance warning of battery discharge
-Power-on delay
-Full microprocessor control.
-Automatic bypass without interruption
-Statuses, readings, alarms available on standard, backlit display.
-UPS firmware update via PC.
-Input protection via thermal switch that can be reset, in various versions up to 1500 VA.
-Standard back-feed protection: to prevent power returning to the mains.
-Manual switching to bypass.
