SIRIUS Double Conversion On-line UPS

The superior technology of a Sirius allows it be used where the site mains power supply is limited in capacity, or has an on-site generator and/or loads that generate current harmonic problems. Sirius is designed to have a zero-impact on its upstream power supply (mains or generator).

Sirius is the first class in cost saving due to efficiency up to 96.5% providing a 50% saving in energy usage per annum compared to traditional UPS products (92% standard). This exceptional performance can lead to a full initial investment recovery within three years.

Sirius Plus is equipped with a graphic display that provides information, measures, states and alarms regarding the UPS in 5 different languages. Advanced, multi-platform communication for all operating systems and network environments: PowerShield3 monitoring and shut-down software included, for Windows 2008, Vista, 2003, XP; Mac OS X, Linux, Novell and most popular Unix operating systems. RS232 or USB serial ports are also available along with other options on request.

Reliable, filtered, stabilised and regulated sine wave output (double on-line conversion technology VFI according to EN50091-3 standard) with filters for atmospheric disturbance suppression. High reliability: IG BT Technology in rectifier and inverter, high frequency PWM, transformer less, fully digital control with microprocessor, no break static and manual transferring. Zero impact source: power factor correction for unitary power factor and very low input THDI%. First class in efficiency: high operation efficiency up to 96.5% in normal mode, up to 99% in eco mode operation. Low noise levels: the high frequency PWM for rectifier and inverter allows very low audible noise. Flexibility: Sirius can be set for several configurations as normal mode, smart mode and standby off. Maximum reliability: Sirius can work in parallel up to 6 units. The UPS continues to operate in parallel even if one of the communication cables is disconnected. Battery care system: Sirius is suitable for use with sealed VRLA, AGM , GEL or open-vented load acid batteries, Ni-Cd batteries. The system comes with temperature voltage compensation. Deep discharging controlled by microprocessor with load and main levels (sharing power mode suitable within -40% Vin). High power availability: the output factor 0,9 providing up to 15% more active power than a traditional UPS and more load expansion. Low management cost: the transformer less technology allows the lowest footprint in this category. The Sirius design allows front, top, and sides access.
