Our Products



Single phase and three phase UPS from 400 VA to 6.4 MVA, for applications ranging from home offices to large industrial plants to data centres.

UPS systems have three features: Safety, Reliability and Availability.

Sentinel Pro

Power Range:  700 – 3000 VA

SENTINEL PRO is an on-line double-conversion UPS offering the highest levels of reliability and protection for critical servers, voice and data processing IT systems.
For long runtime applications, Sentinel Pro (ER models) can be fitted with matching battery extension packs which also include additional battery boost chargers.
In terms of communications, each Sentinel Pro has a built-in mimic panel with an LCD to show input and output voltages, and battery charge status.

The UPS is highly efficient. SENTINEL PRO is designed to save energy and has a power-off push-button feature to reduce energy consumption to zero, when no load is connected or switched off. Sentinel Pro models include 700VA, 1000VA, 1500VA, 2200VA and 3000VA.

Sentinel Power Green

Power Range:  6 – 20 kVA

Sentinel Power Green is the ideal solution for protecting IT systems, telecommunications equipment and mission critical systems such as safety devices, ensuring maximum power reliability.
Sentinel Power Green is designed and built using state-of-the-art technology and components to provide maximum protection to the powered loads with no impact on downstream systems and optimised energy savings.


The series includes 6 kVA single/singlephase and 8-20 kVA single/single-phase and three/single-phase 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.Input and output filters provide significant further immunity from mains disturbances and lightning strikes.

Multi Power

Power Range:  75 – 294 kVA

The Riello MULTI POWER (MPW) is the ultimate modular UPS for DATA CENTRES and other CRITICAL LOADs.
The MULTI POWER is designed to protect any critical high-density computer and IT environment, whilst achieving maximum availability. The MPW grows along with the demands of the business without oversizing the UPS – optimizing both the initial investment and the Total Cost of Ownership.


The new MPW Power Modules feature the very latest in UPS technology. With its three level Neutral Point Clamped (NPC) inverter and Power Factor Corrected (PFC) input control, the MPW ensures the highest level of performance in terms of overall efficiency, input power factor and harmonic impact on the supply source.

Net Power

Power Range:  600 – 2000 VA

The NetPower series includes the 600-2000VA models and uses digital Line Interactive (VI) technology.
The load is powered from the mains through an AVR to stabilise brownout, sag and surge voltages, and EMI filters to suppress spikes and transients. When the mains fails, the load is powered by the inverter with a pseudo sinewave to provide sufficient runtime for computer system shutdown using the PowerShield.
