The Quint UPS-IQ 500 VA ac UPS has received UL 1778 recognition. The industrial control cabinet is certified for Class I, Div. 2 hazardous locations. The rail-mounted UPS monitors a scalable battery solution and provides users with critical operating data. The batteries range from 1.3- to 38-Ah lead acid and include a lithium-ion 120-Wh version. Each of the batteries has an individual UL listing for CID2 hazardous locations. IQ technology manages the battery status and displays relevant data on the UPS’ front panel or transmits it to a computer using Modbus serial so that users always knows the charge state, remaining buffer time and expected lifetime.
