Thermal Considerations
7.1.
Available Processors
Please refer to the chapter 12/ “Technical Specifications”.
The list of processors is not complete and may be extended over the product lifetime.
7.2.
Convection Cooling
The KBox C-103-CFL is designed for convection cooling within the specified ambient air temperature ranges.
Therefore it is imperative that air flow to and from the unit is guaranteed.
In addition, implementers must empirically verify the cooling concept for the KBox C-103-CFL including optionally
installed devices prior implementing the unit in the intended application.
7.3.
Active Cooling via the optional Fan Tray
For applications where convection cooling is not sufficient, there is the possibility to use the optional fan tray
(externally mounted to the KBox C-103-CFL-4/-2/-1). The optional fan tray extension allows to operate the system at
higher ambient temperature conditions and provides a higher air flow through the chassis providing a better cooling
of the system internal components.
7.4.
Minimum System Clearance
To provide a maximum of airflow through and around the box, minimum distances to surrounding parts must be
observed (please refer to the subsection 8.2 “Control Cabinet Mounting” and Figure 46 to Figure 52).
7.5.
Maximum Temperatures
As the Intel
®
processors provide only certain settings for maximal power consumption some typically are used for the
following table. This table can be seen as a guideline.

The 1/2/4-slot variants of The KBox C-103 must only be operated with fan tray.
The 0-slot variant, which has no fan tray option, may be operated without fan tray.
Operation of the 1/2/4-slot variants without fan tray is not approved by UL,
UL certification in progress.
