Current derating as a function of the ambient temperature
Permissible output current as a function of the ambient temperature
The devices and the associated system components are rated for an ambient temperature of
40° C and installation altitudes up to 2000 m above sea level. The output current must be
reduced if the devices are operated at ambient temperatures above 40° C. Ambient
temperatures above 55 °C are not permissible. The following table specifies the permissible
output current as a function of the ambient temperature.
