Riello UPS Master HP UL Online UPS - MHT Series

The Riello Master HP UL is a three-phase double conversion online UPS available in models ranging from 65 kVA to 500 kVA. Designed for critical infrastructure, it uses IGBT technology and digital signal processors to ensure stable power delivery. Procure.ae supplies this series across the UAE and wider MEA region.

This online UPS series delivers VFI SS 111 classification per IEC EN 62040-3, ensuring zero ripple output and sinusoidal waveform stability within ±1% static limits. The IGBT rectifier achieves less than 3% THDi input distortion with a frequency tolerance of ±2%. Operating temperatures range from 0 to 40 °C with humidity support up to 95% non-condensing.

Available in ten part numbers from MHT 65 UL to MHT 500 UL, the system supports single module or parallel configurations. It accepts 480 V three-phase input at 45-65 Hz and outputs 60 Hz power with galvanic isolation. Procure.ae provides quotation services for bulk projects in Dubai Silicon Oasis.
