Power Resiliency Matrix
The TV2 monitor is powered with USB power from either a wall socket or a PC normally. However an internal rechargeable Lithium-Ion battery operates the system for up to 100 hours during primary electrical line failures. While running on backup power, the device continues all logging, audio-visual alarms, relay trips, remote network notifications, and chart queries uninterrupted. If power is out for more than 100 hours all of your data is still safe. It is stored in on-board SRAM within the monitor itself. So even if power is missing for weeks the data is still available and can be displayed or downloaded once power is restored.
