Output derating
When the ambient temperature e60℃, reduce the output power in accordance with the output derating
chart below.
When the ambient temperature is affected by the heat generated by surrounding components, then the ambient
temperature measurement point must be made in proximity to the heat generating components as shown below
When there are no heat generating parts nearby, make the temperature 20mm from the module and 20mm above
the circuit board the ambient temperature.
