SIRIUS 10kVA to 20kVA single or three phase input / single phase output online UPS
The Sirius is ideal for the protection of critical information and telecommunications networks which cannot run the risk of being powered from a poor quality electrical supply. Sirius has been designed and manufactured using state-of-the-art technologies in order to deliver maximum protection for critical users, a zero impact on the mains power supply and a high operating efficiency.
The Sirius series is available in 10-12-15-20 kVA three-phase and single-phase input and single-phase output models, and 10-12-15-20-30-40-60-80-100-120 kVA three-phase input and output models, with double conversion on-line technology according to the VFI-SS-111 classification. Sirius has IGBT Rectifier built in power factor compensation technology and it has a transformer-less Inverter with high frequency PWM.
The superior technology of a Sirius can 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). The power factor correction for unitary power factor is THDI < 3%.
