Riello UPS Master HP UL Online UPS (65-500 kVA) - MHT Series

The Riello UPS Master HP UL series comprises high-performance three-phase online uninterruptible power supplies with capacities ranging from 65 kVA to 500 kVA. Designed for mission-critical applications, these units feature double-conversion topology and galvanic isolation. Procure.ae supplies this equipment across the UAE with professional installation support.

These three-phase online UPS systems operate with a VFI SS 111 classification per IEC EN 62040-3, ensuring continuous power integrity. The series utilizes IGBT sinusoidal rectifiers and digital signal processors to maintain less than 3% THDi input current distortion. Output stability is precise, with dynamic voltage regulation between ±5% and ±1% within 20 milliseconds and static stability at ±1%. Frequency stability remains constant at 0.05%, delivering clean sinusoidal waveforms for sensitive IT infrastructure.

The Master HP UL series accepts a 480 V three-phase plus neutral input with frequencies from 45 to 65 Hz, converting it to a stable 60 Hz output. Operating in environments between 0 and 40 °C with less than 95% non-condensing humidity, these units protect critical loads effectively. Installation of this equipment can be arranged by Procure.ae for buyers across the UAE and wider Middle East & Africa (MEA) regions.
