Determining Power Requirements
Tables 3-1 and 3-2 are provided for calculating the
total current requirements for those parts of the
system requiring battery backup.
Table 3–1—
Standby Current Requirements at 24 vdc
Note: Standby current is the average current draw for the device in normal mode.
This table is for battery calculations only.
