Riello UPS Spa products

Sentinel Pro has a unique, modern design and improved performance created by the Riello UPS research and development team. Sentinel Pro uses ON LINE double conversion technology, resulting in the highest levels of reliability and maximum protection for critical loads such as servers, IT and voice/data applications.

Sentinel Dual is the new range of high density double conversion ON LINE UPS suitable for powering a wide range of devices such as servers, storage systems, VoIP telephony equipment, network and medical systems as well as industrial applications.

The SENTINEL DUAL (High Power) range is available in 3.3-4 kVA single-phase models and 6.5-8-10 kVA three-phase/single-phase models, with on-line double conversion (VFI) technology. The DIALOG DUAL range may be placed directly on the floor or mounted in 19” rackmount cabinets such as the Multi Shelter range. In terms of technology, features (selectable On-line, Economy and Smart Active operating modes), and diagnostics such as the digital display, RS232 and USB interfaces, network adaptor card option and PowerShield³ software include. SENTINEL DUAL (High Power) is easily the best solution for protecting "mission critical" applications requiring the highest levels of reliability. SENTINEL DUAL (High Power) is ideally suited for a whole range of applications from IT to security.

Sentinel Dual is the best solution for powering mission critical applications and electro-medical devices requiring maximum power reliability. The Sentinel Dual range is available in 4 kVA and 5-6-8-10 kVA/kW models with ON LINE double conversion technology (VFI): the load is powered continuously by the inverter which supplies a sinusoidal voltage, filtered and stabilised in terms of voltage, form and frequency. Reduce your power consumption using ECO and SMART ACTIVE modes. Prioritise your most critical loads with EnergyShare sockets that enable easy load-shedding. Load-controlled fans minimise noise disruption (

Our third generation of transformerless ON LINE UPS systems. The 10-20 kVA Sentryum rewrites the concept of flexible power by offering a choice of three compact cabinet sizes to suit the needs of any small data centre or mission-critical application. Enhanced overload and short circuit capacity guarantee maximum availability. Incorporating a 5-inch colour touchscreen display and intuitive LED status indicator that automatically changes colour based on the UPS’s current operating state. 

The Master HE series from 100 to 800 kVA are the Riello UPS solution for installations requiring high energy efficiency and maximum power availability. Master HE Series provides maximum protection and power quality for data centres and industrial loads. The UPS has an IGBT-based rectifier, DSP (Digital Signal Processor) technology and provides true-line, double conversion power protection, (VFI SS 11 - Voltage and Frequency Independent in accordance with IEC EN 62040-3).

Our third generation of transformerless ON LINE UPS systems, the 10-40 kVA Sentryum rewrites the concept of flexible power by offering a choice of three compact cabinet sizes to suit the needs of any small data centre or mission-critical application. Enhanced overload and short circuit capacity guarantee maximum availability. Incorporating a 5-inch colour touchscreen display and intuitive LED status indicator that automatically changes colour based on the UPS’s current operating state.

Riello UPS MULTI POWER (MPW and MPX) is a three-phase uninterruptible power supply with a modular architecture, ON LINE Double Conversion type, with the possibility of redundant. It delivers a rated power from 15 to 1176 kW and it is manufactured using specially-designed components and transformerless technologies that deliver exceptional efficiency up to 96.5%, and high power density in a compact footprint. Modularity reduces the risk of wasteful oversizing at installation, while offering “pay as you grow” scalability when it’s time to expand, optimising initial investment and total cost of ownership (TCO).

Maximum protection and performance: The Master HP series from 100 to 600 kVA is the Riello UPS solution for installations requiring high energy efficiency and maximum power availability. Master HP Series provides maximum protection and power quality for data centres and industrial loads. The UPS has an IGBT-based rectifier, DSP (Digital Signal Processor) technology and provides true-line, double conversion power protection, (VFI SS 11 - Voltage and Frequency Independent in accordance with IEC EN 62040-3).

DC BUS 220 Vdc - Ideal for industrial installations. Master Industrial series UPS provide maximum protection and power quality for any type of load, especially industrial applications, such as manufacturing and petrochemical processes, electrical distribution and power plants. Master Industrial is an ON LINE double conversion UPS (class VFI SS 111 in accordance with IEC EN 62040-3) with input and output isolation transformers.
