• Rack or Tower installation by simply turning the display and adding the supplied handles or optional runners;
• LCD screen;
• LED status bar indicating the UPS operating mode;
• Remote UPS shutdown;
• Configurable via UPStoolsBT app;
• Available in different power ratings, from 1 kW to 3 kW;

• Dedicated matching battery cabinets with various capacity available.

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. Sentinel Dual2 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.

• Even with non-linear loads (IT loads with a crest factor of up to 3:1);
• High short circuit current on bypass;
• High overload capacity: 150% by inverter (even with mains failure);
• Filtered, stabilised and reliable voltage (ON LINE double conversion technology (VFI compliant with EN62040-3) with filters for the suppression of atmospheric disturbances;
• Power factor correction: UPS input power factor 1 and sinusoidal current uptake.

• Automatic and manual battery test;
• Batteries are user replaceable without switching off equipment and without interruption to the load (Hot Swap);
• Unlimited extendible runtime using matching battery cabinets.

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.

• Output voltage can be selected via software (220/230/240 V);
• Auto-restart when mains power is restored (programmable via software);
• STANDBY ON bypass: when the machine is switched off, it automatically goes into bypass and battery charge mode;
• Minimum load switch-off;
• Battery discharge warning;
• Start up delay;
• Total microprocessor control;
• Automatic bypass without interruption;
• Status, measurements and alarms available on standard backlit display;
• UPS firmware updating via PC;
• Input protection via resettable thermal switch (versions up to 1500 VA);
• Backfeed protection standard: to prevent energy from being fed back to the network;
• Configurable via UPStoolsBT bluetooth app;
• Manual switching to bypass.

Sentinel Dual2 offers maximum flexibility for integration with all types of communication systems.
