The Riello UPS Master HP range has zero impact on connected power sources such as grid networks or generators and delivers a unity power factor. With an IGBT-based rectifier, it achieves exceptional operating efficiency compared to a more conventional thyristor-based rectifier. While its output isolation transformer means the Riello UPS Master HP can be supplied by 2 independent lines, has a higher immunity to harmonics, and provides all-around better load protection.

The mains input quality is constantly monitored, with the UPS system selecting the most appropriate and efficient operating mode based on any interference (Smart Active mode with up to 98.5% efficiency) or circular redundancy (Parallel Energy Saving mode).

UPS maintenance on the Riello UPS Master HP is easy thanks to a removable front panel, while high power is achieved in a compact, space-saving footprint.

The Riello UPS Master HP is available in 9 power ratings from 100-600 kVA, so up to 8 UPS systems can be installed in parallel to provide the necessary redundancy and capacity. Systems can be installed in centralised or decentralised architecture and in a variety of configurations, including: 

  • UPS Group Synchroniser (UGS): enables 2 or more non-parallel UPS devices to remain synchronised even during mains power failure. UGS also enables a Riello UPS to synchronise with another independent power source, even one with a different power rating. 
  • Parallel Systems Joiner (PSJ): this connects 2 groups of UPS in parallel using a power coupling switch. If one of the UPS in the group fails, it is automatically excluded and the PSJ links the remaining UPS to the other group through an external bypass.
