The NetPower series includes models ranging from 600 to 2000 VA and utilizes digital line-interactive (VI) technology. The load is supplied from the power grid through an automatic voltage regulator (AVR) to stabilize voltage drops, fluctuations, and spikes, as well as with EMI filters to suppress surges and transients. In the event of a power failure, the load is powered by the inverter with a pseudo-sine wave to ensure sufficient runtime for safely shutting down the computer system with PowerShield.
- Stabilization and filtering of the mains power supply (line-interactive (VI) technology with AVR and filters to suppress atmospheric disturbances).
- Cold start function: The UPS can be turned on without an existing power supply.
- High reliability with an integrated battery test function.
- Supplied with 2 output cables.
- USB port.

Sentinel Dual is the best solution for powering mission-critical applications and electro-medical devices that require maximum power reliability.
The Sentinel Dual series is available in 4 kVA and 5-6-8-10 kVA/kW models with online double conversion technology (VFI): The load is continuously supplied by the inverter with a sine wave voltage that is filtered and stabilized in terms of voltage, shape, and frequency.
Reduce your power consumption with ECO and SMART ACTIVE modes. Prioritize your most critical loads with EnergyShare outlets that enable easy load management. Load-controlled fans minimize noise disturbance (less than 48 dBA).


In Switzerland, the connection and commissioning of a UPS with > 3.5 kVA must be clarified in advance with the local electricity provider. The connection must be carried out by an electrician.

The Riello Sentinel Dual is a state-of-the-art uninterruptible power supply (UPS) featuring double-conversion technology that ensures reliable power for critical applications.

Operating Principle The Multi Switch ATS allows for the direct distribution of eight 10 A IEC outputs or one 16 A IEC output in the 16 A model, four 10 A IEC outputs, one 16 A IEC output, or a power strip in the 30 A model within a system with two input power lines (two mains connections or two UPS units). The Multi Switch ATS can be connected to either of the two input power lines while simultaneously monitoring power consumption. Protection Against Load Failures If one of the loads fails (e.g., short circuit), the Multi Switch ATS disconnects the group of sockets to which the load is connected, thereby preventing other loads from being shut down (i.e., in the event of poor differentiation of the protective devices). Protection Against Power Supply Failures If one of the two power sources is outside the tolerance limits, the Multi Switch ATS transfers the load to the second power source (the switching process occurs immediately when both sources are synchronized).

The Sentinel Dual is a new series of extremely powerful online double-conversion UPS systems designed to protect a wide range of devices, such as servers, disk storage, VoIP phone systems, networks, and industrial applications.
It is ideal for powering blade server systems that feature power supplies with a high power factor. With a height of only 2U, the Sentinel Dual is perfectly suited for installation in 19” racks.
You will appreciate the modern design and improved performance, which are the result of continuous technological advancements from the Riello UPS laboratories.
The newly developed inverter is one of the most economical on the market, with a power factor close to 1 and an efficiency of 92% in online operation.
For business processes that require a long autonomy time, the battery backup time can be easily extended to several hours by using the ER version, which has a larger charging unit.
Riello UPS has introduced a switch to optimize energy savings in the Sentinel Dual series, reducing energy consumption to zero during periods of inactivity (ECO LINE).

Sentinel Dual is the best solution for powering mission-critical applications and electro-medical devices requiring maximum power reliability. The flexibility of installation and use (digital display, user-replaceable battery set), as well as the many communication options available, makes the Sentinel Dual suitable for many different applications from IT to security. Up to three Sentinel Duals can be operated in parallel in either capacity or N+1 redundant configuration, offering increased reliability for critical systems. The Sentinel Dual can be installed as a tower (floor standing) or rack, ideal for network and server rack applications.
The Sentinel Dual range is available in 5, 6, 8, and 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 stabilized in terms of voltage, form, and frequency. In addition, the input and output filters significantly increase the load’s immunity to mains disturbances and lightning strikes. Technology and performance include selectable Economy Mode and Smart Active Mode functions. Diagnostics feature a standard digital display, RS232 and USB interfaces with PowerShield3 software downloadable, and a communications slot for connectivity accessories.
