  • Power Rating: 10-200 kVA
  • Low input current distortion – less than 3%
  • High input power factor 0.99
  • Power walk-in function to achieve progressive rectifier start-up
  • Delayed start-up on mains power supply return
  • Available in 10-12-15-20-30-40-60-80-100-120-160-200 kVA all with a three-phase input and output

The Riello Multi Sentry UPS also performs the role of a high specification filter, protecting its power supply sources (mains or generator) from any harmonics and reactive power generated by the loads it is powering.

APC has been the industry standard for reliable power supplies for nearly four decades. Its history of innovation, and focus on research and development, has seen the brand go global, with APC UPS products now protecting critical power applications for organisations around the world.
