Table 2
illustrates the current draw of each module at -48 V.
illustrate three different Total Access 3000/3010 arrangements with a current draw
of -48 V. Use
determine wire gauge and fuse size. Use
calculate current draw for a single shelf deployment.
Table 2. Current Draw of Each Module At -48 V
Note: * The following equations are used for calculating T1-OR current draw and depend on span powering for
loop equipment and voltage input:
Nominal:
(48 V/input voltage * (14.8 + span ohms / 10.16) + 45) mA
Maximum:
(48 V/input voltage * (15 + span ohms / 10) + 50) mA
