Current consumption calculation
Current consumption values described for each interface is the current consumption
for that interface only. To calculate the total current consumption values shall be added
together.
For example a unit with the following configuration will be calculated as follows:
Used modules Consumption
Power and CPU 410 mA @ 20 VDC
8 copper ports 144 mA @ 20 VDC
F4G 360 mA @ 20 VDC
Adding the values will give a total consumption of 914 mA @ 20 VDC.
external power supply must be rated to meet the calculated current.
Westermo recommends external power supply to be rated for a startup current which
is at least twice the calculated in service consumption. in the example above an external
power supply must be rated for at least 1828 mA for startup current.
