High-efficiency three-phase transformer-based UPS with IGBT rectifier, unity output power factor (kW=kVA), galvanic isolation and up to 99% ECO Mode efficiency. Ideal for data centers, industrial loads, e-medical and emergency applications.
The Riello Master HE is a high-efficiency, three-phase online double-conversion UPS designed for large data centers, industrial processes, and critical infrastructure. Its cutting-edge power electronics deliver class-leading efficiency combined with low input current distortion and unity input power factor.
Available from 100 to 800 kVA in a single frame and expandable in parallel, the Master HE is well suited to Tier III data centers, healthcare campuses, and large industrial facilities where both availability and energy cost matter.
Up to 96.5% efficiency in online mode and 99% in Smart Active mode significantly reduces energy costs and cooling load across the UPS lifetime.
Unity input power factor and input current distortion below 3% eliminate harmonic oversizing of transformers, generators, and cabling upstream of the UPS.
Up to eight units can be paralleled for capacity or redundancy, supporting N+N and N+1 architectures required by the most demanding critical sites.
A color graphical touchscreen, standard network communications, and comprehensive protocol support simplify integration and long-term operations.
