DIALOG DUAL 3300-10000VA floor or 19" DLD Series

An Uninterruptible Power Supply (UPS) for the power protection of medium sized file servers, voice and data networks, communications cabinets and telephone switches.

The Riello UPS Dialog Dual UPS range is the ideal solution for computer and telecoms users wanting a flexible multiple operating format power system capable of either floor standing or 19" rackmount format for use in communication cabinets. In 2004 the product won the Electrical Products Award for innovation.

Uninterruptible Power Supply with multiple operating modes
The Dialog Dual UPS is available in 3300-10000VA (single/single phase models) and uses double conversion on-line technology (VFI) with several other operating mode options. Dialog Dual TM models have a three-phase input with a single phase output.

In on-line mode the load is powered continuously by the inverter to remove sags, surges and brownouts, through EMI filters to suppress transients, spikes and electrical noise. Even on bypass the load is routed through the filters so that the load is not connected to raw mains.

When the mains fails, the inverter which is constantly powering the load simply draws power from the internal battery to provide complete protection.

Extended Runtimes
As the inverter is rated for continuous operation this type of uninterruptible power supply can be used to support large loads for long runtimes up to and over 7 hours or more in duration. This can be achieved using battery extension packs that connect in series to the rear panel connector on the UPS and/or a generator. When battery extension packs are used these may have their own mains powered chargers to maintain a reasonable recharge time of the complete battery set. For larger loads consider the Power Dialog Plus.

Whatever the runtime installed there should be sufficient time for the protected computer systems to be shutdown in an orderly manner using the PowerShield software, supplied as standard. Additional remote monitoring can be achieved using PowerNetGuard on Wide Area Networks or the TeleNetGuard remote service monitoring system with text alerts for site problems, and the wide range of NetMan SNMP interfaces and MultiCom adapters available.

Advanced Communication
Advanced, multi-platform communication for all operating systems and network environments: PowerShield UPS monitoring and control software included, with SNMP agent, for Windows 95, 98, 2000, 2003, Me, XP, Mac OS X, 9.x, Linux, NT 4.0, Novell operating systems.

the UPS is supplied with a communications cable for ‘Plug and Play' PC connection
RS232 serial port (double serial port optional)
network adapter slot for SNMP agent
rear panel IEC socket for supplying local loads
EPO (Emergency Power Off) contact for remote UPS shut-down
Installation and Ease of Use
the UPS can be installed as a floor standing tower or 19” rackmount. The front panel digital display can be pulled out (using the keys provided) and rotated to suite the installation format
low noise level (20kHZ, above the audible range). Dialog Dual is suitable for installation in any populated environment.
UPS Operating Modes
As well as the its on-line operating mode, Dialog Dual can operate in:

Economy: the UPS mimics a Line Interactive (VI) UPS supporting the load from its battery supply when the mains fails or fluctuates wildly
Smart Active: the UPS selects automatically whether to operate in On-line (VFI) or Line Interactive (VI) mode depending on the stability of the mains supply
Emergency: the UPS only supports the load with its batteries when the mains fails - suitable for emergency lighting
Frequency conversion: 50 or 60Hz
Other use selectable customisation points include:

output voltage selection: 220-230-240Vac
auto restart on mains return set from the front panel or PowerShield software
automatic output delay when the UPS powers up
automatic power down when no load is present
end of battery discharge pre-alarm
Power Quality
filtered, stable and regulated - double conversion on-line (VFI) technology in accordance with EN50091-3, a with EMI filters
guaranteed output quality even with typical distorting IT loads with crest factors of 3:1
low impact on the mains supply as the UPS has an input power factor close to 1, with a sinusoidal input current
High Reliability
completely digitally controlled
uninterrupted automatic by-pass
the by-pass can be activated manually
use of IMS (Insulated Metallic Substrates) modules
Advanced Diagnostics
status, measurements, and alarms available on the standard backlit display
UPS can be updated digitally (flash upgrade able)
Optimal Battery Management
reliable battery performance (automatic and manual battery tests)
prolonged battery life due to the unique Low Ripple Current Discharge (LRCD)
‘hot-swap' user replaceable batteries
extendible back-up time using additional battery extension packs or trays
increased ride through (without batteries) on mains breaks up to 40ms and for fluctuations ranging from 84 to 276Vac
Enhanced Electrical Performance
input protected by resettable thermally activated switch
back-feed protection: to avoid energy being fed back into the mains should a fault occur
increased short circuit current on the by-pass
increased overload capacity: 150% on inverter even without a mains supply present
performance guaranteed in temperatures up to 40°C
manual switch to by-pass
