These products have been tested for use in 50 degrees Celsius (
º
C) ambient, still-air locations (60 degrees
Celsius (
º
C) ambient for the Headless unit). This means that when installed, the ambient air surrounding
the unit is not expected to exceed 50
º
C. An example of this type of installation would be the PowerStation
mounted in a small, sealed industrial enclosure.
The most commonly overlooked aspect of this type of installation is that heat generated by the device, and
other devices in the enclosure, becomes trapped and increases the ambient temperature immediately
surrounding the PowerStation. This increase in temperature can sometimes exceed an additional 10
º
C or
more. To assist in calculating the enclosure minimum volume, the section, Electrical Specifications in
Appendix A of this document, contains the thermal heat dissipation (Watts) associated with each
PowerStation size.
Although the thermal dynamics are not always linear, a temperature rise of 10
º
C degrees inside the
enclosure would imply that the environment outside the sealed enclosure could not exceed 40
º
C for the
display based systems, or the product would surpass its maximum operating temperature.
Therefore, do not install the PowerStation with its 50
º
C operating temperature limit into a sealed
enclosure without considering the effects of the internal heat buildup.
Since elevated operating temperatures can have an adverse effect on the life of electronics, it is wise to
consider the internal thermal rise. Passive venting for thermal convection, internal air circulation fans,
filtered exhaust fans with filtered inlets, air conditioners, and other products are available in the market to
assist in reducing the heat buildup in the industrial enclosure.
There are many attractive industrial IP65, dust-tight fan/filter assemblies available today which allow the
filter to be inexpensively replaced or cleaned as part of a periodic maintenance schedule. In some cases,
thermal response.
Here are some points to consider when performing a site review:
◼
What is the expected maximum outside ambient temperature surrounding the industrial
enclosure?
◼
Are there any additional heat-generating components inside the enclosure?
◼
What is the size of the enclosure? Larger enclosures dissipate more thermal energy than smaller
ones.
◼
What kind of environment will the enclosure be installed in - clean, water-tight, dust tight? Can
the enclosure be convection cooled or is active cooling required?
Itis a wise investment to thermally plan the installation by anticipating and eliminating the heat build-up
inside a sealed enclosure. Not only will this extend the life of the electronics, but it will also reduce costly
equipment downtime.
