Main features:

Operating flexibility

Different operating modes that can be programmed according to on 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
• Economy 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.
• Standby 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 supplied in the event of a mains power failure, such as emergency lighting, fire detection/ extinguishing systems and alarms. When the mains power supply fails, the inverter begins powering the loads with a progressive start¬up (Soft Start) in order to prevent overload.

Battery optimization

The Sentinel Pro range has a deep discharge protection device to optimise battery life. Periodically the UPS carries out a battery efficiency test (which can also be manually activated); its wide input voltage tolerance range helps to reduce battery usage and maintain performance over time.

Runtime expandability

Optional battery extension packs can be connected to increase UPS runtime. In addition, the Sentinel Pro range includes ER versions with no internal batteries and more powerful battery chargers for 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.

Other Features

• Filtered, stabilised and reliable voltage: double conversion on-line technology (VFI compliant with IEC 62040-3) with filters for the suppression of atmospheric disturbances.
• High overload capability (up to 150%)
• Programmable Auto-restart when mains is restored
• Battery start-up (cold start)
• Power factor correction (UPS input power factor, dose to 1)
• Wide input voltage tolerance range (from 140 V to 276 V) without battery intervention.
• Fully configurable using UPS Tools configuration software
• Low impact on the mains (sinusoidal take up).
