Models with the suffix "ER" do not have built-in batteries.
o Sentinel Pro has a unique and modern design with improved performance, developed by Riello UPS and the research and development department. 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 telecommunications equipment.

The display face has been completely redesigned, and an LCD screen has been added that shows input and output voltages, battery readings and UPS operating states. The inverter and microprocessor control circuit have been completely redesigned and provide greater efficiency and more setting options. Maximum expandability: the Sentinel Pro series provides as standard a USB port and an expansion port for the protocol converter or card with relay contacts.

With energy savings in mind, the Sentinel Pro is also equipped with a stop button to reduce energy consumption to zero during extended periods of inactivity (ECO LINE). The Sentinel Pro is available in 700 VA, 1000 VA, 1500 VA, 2200 VA and 3000 VA models.

Flexibility of operation
Different operating modes can be programmed according to user requirements and load type, in order to reduce energy consumption.
On line: maximum load protection and high quality output voltage waveform
Economy mode: the UPS uses line interactive technology, with the load being supplied from the mains, reducing consumption and improving efficiency (up to 98%).
Smart mode (Smart Active): the UPS automatically selects its mode either on-line or line-interactive, depending on the quality of the power supply, controlling the number, frequency and type of power disturbances.
Stand by Off (emergency): The UPS supplies the load only when there is a power failure.
Frequency converter operation (50 or 60 Hz).

Emergency mode
This arrangement ensures the operation of emergency loads that need to be powered in the event of a power failure, such as emergency lighting, fire detection / fire extinguishing and alarm systems. When the power supply is interrupted, the inverter starts supplying the loads with the soft-start process to avoid an overload.

Optimization of accumulators
The Sentinel Pro series has a battery deep discharge protection system to optimize battery life. At regular intervals the UPS checks the performance of the batteries (which can also be done manually). The wide input voltage range helps reduce battery usage and maintain performance over time.

Autonomy extension
Optional battery extension cabinets can be connected to the UPS to increase its autonomy. In addition, the Sentinel Pro range includes ER versions without internal batteries, with more powerful battery chargers for longer runtimes.

Low noise level
Thanks to the use of high-frequency components and the control of the fan speed in relation to the load, the noise produced by the UPS is less than 40 dBA.

Important features:

Filtered, stabilized and reliable electricity using On-line double conversion technology (VFI compliant with IEC 62040-3 standard) with filters to suppress atmospheric disturbances.
High overload capacity (up to 150%).
Programmable automatic restart when power is restored.
Starting operation from batteries (cold start).
Power factor correction (UPS input power factor, almost 1).
Wide input voltage range (from 140 V to 276 V) without battery operation.
Fully configurable using UPS Tools software.
Low impact on the power grid.
Advanced Communications
The advanced communication platform is compatible with all operating systems and network environments:

PowerShield3 monitoring and shutdown software for Windows 8, 7, Hyper-V, 2012, 2008, and earlier, Mac OS X, Linux, VMWare ESXi, Citrix XenServer, and other Unix operating systems.
RS232 serial port and optically isolated contacts.
USB port.
Contact card slot.
