A-10 Specifications
Power Dissipation The power dissipation characteristics of the 1394 system and axis
modules are provided below (use for 480V or 360V input).
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).
System Modules
The power dissipation (in watts) of the system module types is shown
below.
Axis Modules
The power dissipation (in watts) of the axis modules is shown below:

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.
