Note:
TRCS does a look-up in the Rockwell Automation Components database. Th e power-loss
data for all components are stored there as follows:
P •
0
Constant losses (e.g. power supply, contactor coils)
P •
1
Losses proportional to the current (~ I; e.g. power semi-conductors)
P •
2
Losses proportional to the square of the current (~ I 2 ; e.g. conductors, fuses,
contact systems)
I •
ref
Reference current for P
1
and P
2
(current where P
1
or P
2
occur)
