Reliability Reliability - Soul of UPS New system-level reliability design ITA2 is equipped with the latest generation of control chip. Control frequency and performance of the system are doubled. ITA2 is designed with innovative "independent air flow channel" to isolate sensitive components, completely solving the UPS failures caused by dust and conductive powder and doubling the reliability of the system. Excellent electrical performance ensures normal operation of the UPS for a long time. ITA2 UPS passes rigorous test system and certification system. • Hygroscopic dust test • High altitude test • High and low temperature design margin test • Seismic test • Vehicle vibration test • Fire test • CE • TLC • CQC • Energy Star • Seismic technology  certification • Rohs Rigorous test system Perfect certification system 60 years of UPS technology accumulation presents extraordinary new products Excellence Excellent electrical parameters Excellent physical specifications Output power factor of the whole series of ITA2 is increased to 1. KVA = KW. The load capacity is enhanced by 20%. Input voltage range is improved to 100 - 288V, preventing the UPS from frequently switching to battery mode due to voltage fluctuation. Overload capacity is improved to 150% , 1min, preventing the UPS from frequently switching to bypass mode due to short time load impact. System efficiency is increased to 96%, and energy saving rate doubled. Charging capacity up to 13A (long back-up time model) Power consumption cost (0.75 yuan/ kWh) Based on efficiency of 0.9 Based on efficiency of 0.92 Based on efficiency of 0.94 0.96 6,570 4,928 -8,212 -5,356 -2,621 0.95 8,299 6,224 -6,916 -4,059 -1,324 0.94 10,065 7,549 -5,591 -2,735 0 0.93 11,868 8,901 -4,239 -1,382 1,353 0.92 13,711 10,283 -2,857 0 2,735 0.91 15,595 11,696 -1,444 1,413 4,148 0.9 17,520 13,140 0 2,857 5,591 Note: Take 20KVA / 18KW load for example. 8,212 yuan annually, 4.38 tons of standard coal  co
