dialog-dual-3,3-10VA-.pngThe DIALOG DUAL Riello UPS series from Riello UPS range is available in 3300-4000- 5000-6000VA models, with on-line double conversion (VFI) technology. 

 The DIALOG DUAL Riello UPS range may be placed directly on the door or mounted in 19” rackmount cabinets such as the Multi Shelter range. In terms of technology, features (selectable On-line, Economy and Smart Active operating modes), and diagnostics such as the digital display, RS232 and USB interfaces, network adaptor card option and PowerShield2 software included, DIALOG DUAL Riello UPS is easily the best solution for protecting “mission critical” applications requiring the highest levels of reliability.
Riello UPS is ideally suited for a whole range of applications from IT to security.


  • The UPS can be installed as a floor standing tower or 19” rack mount UPS. The front panel digital display can be pulled out (using the keys provided) and rotated to suite the installation format
  • Reliable, filtered, stabilized and regulated sinewave output (double conversion technology VFI in conformity with IEC 62040-3 specifications) with filters for atmospheric disturbance suppression
  • Low noise level (<40dBA) thanks to the digitally PWM controlled ventilation system which is load and temperature dependent, and the use of an inverter with a high switching  frequency (>20kHZ, above the audible range)
  • Optional bolt-on maintenance bypass (DLD 500/600 models) to allow service without disruption to the loads
  • User selectable operating modes in addition to true on-line mode
  • Economy Mode: Selects Line Interactive VI technology to power non-critical loads from main and archieve up to 98% operating efficiency
  • Smart Active Mode: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 can be programmed to work only when the mains fails-suitable for emergency lighting
  • Frequency conversion 50 or 60Hz
  • Output voltage selection: 220-230-240Vac
  • Auto restart when mains power returns programmed using the front panel or using PowerShield² software
