The AVE240C series power supplies will start and operate within stated specifications at an ambient temperature from
-40 OC to 85 OC under all load conditions. The storage temperature is -55 OC to 125 OC.
Thermal Considerations
The converter is designed to operate in different thermal environments and sufficient cooling must be provided.
Proper cooling of the DC-DC converter can be verified by measuring the temperature at the test point(s). The temperature
at this/these point(s) should not exceed the max values in the Table 5.
The converter can operate in an enclosed environment without forced air convection. Cooling of the converter is achieved
O
mainly by conduction from the baseplate to a heatsink. The converter can deliver full output power at 85 C ambient
temperature provided the baseplate temperature is kept below the max values in the following table.
