chargers to maintain sensible recharge times.
The UPS also incorporates the Riello UPS ‘power-off’ function found 
in other ECO Line UPS. Premium Dual is designed to save energy 
when no loads are connected.

SimPliFieD iNStallatioN
• Tower or Rackmount UPS: Premium Dual can be installed as tower 

or 19” rackmount UPS, with a front mimic panel that can be turned 
through 90º to suit the installation.

• Noise Free Operation (<40dBA): the UPS can be installed in any 

environment thanks to its PWM digitally-controlled high frequency 
inverter.

• High Temperature Operation: UPS components are sized for high 

temperature operation up to 40ºC and are not therefore stressed 
during normal operational environments.

• EnergyShare: Premium Dual output sockets can be programmed to 

disconnect less critical loads when the mains power fails.

reDuCeD maNaGemeNt CoStS
PREMiUM DUAL can be programmed remotely via software or set 
manually from the front mimic panel to operate in a range of energy 
saving operating modes:
• on line: maximum power protection and output voltage waveform 

quality

• eCo: to increase operating efficiency to 98% and provide line 

interactive protection

• Smart active: with the UPS selecting automatically its operating 

mode - ECO or On-Line dependent upon the reliability and quality of 
the local mains power supply.

• backup: for emergencies only with the UPS only operating when 

mains power fails

• Frequency converter: from 50 to 60Hz or 60 to 50Hz.

and relay contacts.

HiGH outPut VoltaGe Quality
• Even with distorting loads (iT loads with a crest factor of up to 3:1).
• High short circuit current on bypass.
• High overload capacity: 150% from inverter (even with no mains power).
• Filtered, stabilised, reliable (On Line double conversion technology 

(VFi in accordance with EN62040-2 class C1) standard with filters to 

suppress atmospheric disturbances.

• Load power factor correction: incoming UPS power factor close to 1 

and sinusoidal current absorption.

HiGH leVelS oF battery reliability
• Automatic and manual battery tests
• Batteries are ‘hot-swappable’ and user replaceable.
• Unlimited battery runtime extension using battery extension packs.

otHer FeatureS
• Output voltage can be selected using software (220-230-240V).
• Auto-restart when mains power returns (programmed via software)
• Stand-by on Bypass: when the machine is switched off, it 

automatically goes into bypass operation with batteries charging.

• Power-Off with zero load connected to save energy
• Low battery warning
• Power-on delay
• Full microprocessor control.
• Automatic bypass without interruption
• Status, measurements and alarms available on the front panel mimic 

panel and LCD

• UPS firmware upgrade via PC platform
• input protection including a user reset thermal switch (up to 1500VA)
• Back-feed protection
• Manual option to switch to bypass.
