Environmental

• Operating Temperature Range: 0°C to 65°C

• Temperature De-rating: Based on the power applied, maximum operating temperature may have

to be de-rated because internal power regulators dissipate some heat.

For example, when 7.5VDC is applied, the temperature rise inside the enclosure is 7.3°C above the

ambient temperature.

Maximum operating temperature can be determined according to the following equation:

I(TJ = 100)

< 19.6 - T

/6.83

Where T

is the ambient temperature in °C. and V

I(TJ = 100)

is the voltage at which the integral voltage

regulator junction temperature will rise to a temperature of 100 °C.

(Note: The junction temperature is rated to 120 °C. maximum.)

For example, at an ambient temperature of 25 °C., the voltage V

can be up to 15.9V.

At an ambient temperature of 100°F (37.8°C), the voltage V

can be up to 14V.

• Storage Temperature Range: -20 °C. to +70 °C.

• Humidity: 5% to 95% RH non-condensing.
