Basically the available output power is limited by thermal
characteristics. Operation at higher temperatures with
nominal output currents is also possible if forced cooling
can be provided (heat sink, fan, etc.).
Example: Sufficient forced cooling allows
TA max = 65 °C. A
simple check of the case temperature
TC (TC ≤ 80 °C) at full
load ensures correct operation of the system (temperature
measurement point on the case see "Mechanical Data").
In general: For an ambient temperature of 65
°C with only
convection cooling, the maximum permissible current for
each output is approx. 50% of it's nominal value.
