PCS safe operating area
Figure 19:
PCS load resistor-current operating graph.
The operating area of the PCS output is reported in Figure 19. The upper
region between the red curve (maximum PCS output current) and the blue curve
(maximum PCS output current safely sustained by internal electronics) is the
unsafe operating area. The lower region between the blue curve and red curve is
considered safe.
CAUTION
The Persistent Switch Output is not limited by any resistor thus care
must be taken in select the correct current corresponding to the PCS
load resistor. See section 3.3.1 for more details on load resistor.
CAUTION
The Persistent Switch Output is not floating but it is referred to the
Chassis Earth. Connect only to floating Persistent Switch.
