Riello UPS Master HP UL Online UPS - MHT Series

The Riello UPS Master HP UL is a three-phase online uninterruptible power supply series rated from 65 to 500 kVA. It provides zero ripple output with high overload capacity for critical IT infrastructure. Procure.ae supplies this equipment in the UAE and MEA.

This series uses IGBT technology and digital signal processors for double conversion online operation. Input voltage is 480 V three-phase + N with a frequency range of 45 to 65 Hz. Total harmonic distortion is less than 3% THDi, and output frequency tolerance is selectable from ±1% to ±5%. The topology ensures galvanic isolation and sinusoidal output waveform.

Units are available in single module or parallel configurations for scalability. Operating temperature ranges from 0 to 40 °C with relative humidity below 95% non-condensing. The system meets VFI SS 111 per IEC EN 62040-3 and holds UL/CSA, UL Standard 1778, and FCC Part 15 certifications. Protection rating is IP20.
