Environmental Temperature Constraints
No special precautions are necessary over the range of 0°C to 50°C
(32°F to 122°F). For operation at temperatures below 0°C, the PK2200
should be equipped with a low temperature LCD that is specified for
operation down to 20°C. The heating effect of the power dissipated by
the unit may be sufficient to keep the temperature above 0°C, depending
on the enclosures insulating capability. The LCD storage temperature is
20°C lower than its operating temperature, which may protect the LCD in
case the power should fail, thus removing the heat source. The LCD unit
is specified for a maximum operating temperature of 50°C. Except for
the LCD, which fades at higher temperatures, the PK2200 operates at
60°C or more without problem.
External loads and expansion cards can increase power
consumption.
