Appendix E Current Consumption and Heat Dissipation
E.1 General
The tables below present the current consumption and power dissipation of all relevant
hardware modules included in Advant Controller 450 and its I/O.
Use this information:
•
When dimensioning the supply to the system
•
When calculating the heat generated in RM500 cabinet.
The values given in the tables are typical and adapted to these kind of applications.
It is assumed that 70 percent of the channels on a board are active simultaneously.
Use the tables as forms in your own calculation.
E.2 Calculation Algorithms and Forms with Technical Data
Current Consumption
When calculating the current consumption, focus on current per power supply unit.
Consider the available capacity given in
Obtain the current consumption with 24 V, I
tot ,
in the following way:
where
I
24V
= current consumption 24 V, obtained from the tables.
I
5V
= current consumption 5 V, obtained from the tables.
0.37
= conversion factor.
Heat Dissipation
When calculating heat dissipation, focus on heat per cabinet.
Consider the permitted power dissipation given in
Section 3.1.10, Heat Dissipation
.
The total power dissipated in the cabinet can be written:
