Tripp Lite SmartOnline UPS systems feature a combination LCD/LED display which presents a wide variety of UPS operational modes and conditions. This interface provides more information than comparable models, allowing users to react more rapidly to alerts before the systems are put at risk. The LED display presents an intuitive operational block diagram which displays normal on-line operation (I/P, AC/DC, DC/AC and O/P), bypass operation (I/P, Bypass and O/P) or on-battery operation (Battery, DC/AC and O/P). Using the control buttons, a user can access over 45 separate conditions through the LCD display.
