Polar Star is a State-of-the-art device equipped with new functions for monitoring energy consumption and for advanced energy and quality analysis. This device is able to measure, display, process and transmit all the parameters of a plant.

• 4 independent current inputs with a 0.25%+0.05FS accuracy
• 3 voltage measuring channels up to 600V Cat III, with a 0.25%+0.05FS accuracy
• 6 electrical systems which can be analyzed: (i) Single-phase type; (ii)two-phase type; (iii) three-phase with 3 leads (unbalanced type); (iv) three-phase with 4 leads (unbalanced type); (v) three-phase with 3 leads (balanced thpe); (vi)three-phase with 4 leads (balanced type);
• Switching power supply, 90÷230Vac ~ 50-60Hz, 90÷300Vdc
• Energy quality analysis through measuring of: current and voltage harmonics (all 7 input channels) up to the 31st order; power and micro-power blackouts* Dips (voltage losses)* Swells (overvoltages)* EN50160 test (reference standard for energy quality)* Event data logger (5 alarms, 5 dips, 5 swells, 5 interruption)* graphic display of trends (time progress) of 5 selectable measures* energy measurement in 4 time periods (tariffs)* (tariffs can be freely set)
• Automatic test connection for checking the electrical connections
• Automatic option recognition
• Software available for TOP model to monitoring directly the Polar Star
