1394 System Power Dissipation Specifications
The following section contains the power dissipation characteristics of
the 1394 system modules, axis modules, and internal shunt resistors.
System Modules
Axis Modules
1
The AM50/75 are designed to mount with the rear heat sink extended outside the customer-supplied enclosure. If
the modules are mounted entirely inside the customer supplied enclosure, the full power dissipation is inside the
cabinet (the sum of the inside/outside columns).
2
The AM50/75-IH are designed to mount entirely inside the customer-supplied enclosure.
IMPORTANT
Use the power dissipation figures shown below to
calculate cumulative system heat dissipation to
ensure that the ambient temperature inside the
enclosure does not exceed 50° C (122° F). To
calculate total power dissipation, add the dissipation
of the system module to the dissipation of the axis
module(s).
