Sentinel Rack has compact design and improved performance. Sentinel Rack uses on-line double conversion technology, resulting in the highest levels of reliability and maximum protection for critical loads such as servers, and IT and voice/data applications.
For business continuity applications requiring long battery runtimes, battery autonomy can be extended up to several hours using the 3000 VA model fitted with more powerful battery charger. Front display panel has been entirely redesigned, adding an LCD display that shows the input and output voltages, battery readings and UPS operating status information. The inverter and the microprocessor control stage provide increased efficiency and greater configuration options.
Maximum expandability: the Sentinel Rack is supplied as standard with a USB port and an expansion slot for protocol conversion or relay contacts boards. With energy savings in mind, Sentinel Rack is also fitted with a shut-off switch to reduce energy consumption to zero during prolonged periods of inactivity (ECO LINE). Sentinel Rack is available in 1500 VA and 3000 VA models.
Operating flexibility
Different operating modes that can be programmed according to user requirements and the load to be powered have been introduced in order to reduce energy consumption.
- On line: Maximum load protection and output voltage waveform quality.
- Eco Mode: The UPS uses line interactive technology, with the load powered by the mains, reducing consumption and thus improving efficiency (up to 98%).
- Smart Active Mode: The UPS automatically selects on-line or line interactive operation, depending on the quality of the mains supply, checking the number, frequency and type of disturbances present.
- Stand by Off (emergency): The UPS supplies the load only when the mains fails. The inverter begins working with a progressive start-up sequence to prevent inrush currents.
- Frequency converter: operation (50 or 60 Hz).
Emergency function
This configuration ensures the operation of emergency systems that must be operational in the event of a power failure, such as emergency lighting, fire/extinguishing systems and alarms. In the event of a mains power failure, the inverter starts and starts taking over the individual loads gradually (Soft Start) to prevent the UPS from being overloaded. Sentinel Rack complies with the requirements for placing equipment in low-voltage transformer rooms in accordance with current legislation for power supply with a backup energy source.
Battery optimisation
Sentinel Rack is compliant for installation in medium-voltage transformer rooms in accordance with applicable legislation, for the power supply with reserve charge of medium-voltage coils.
Runtime expandability (SER 3000)
Optional battery extension packs can be connected to increase UPS runtime. SER 3000 ER version is designed without internal batteries and a more powerful battery chargers to achieve longer runtimes.
Low noise level
Thanks to the use of high frequency components and load-based fan speed control, the noise produced by the UPS is less than 40 dBA.
