General
The PKJ 4000E Series DC/DC converters are designed
to operate in a variety of thermal environments, however
sufficient cooling should be provided to help ensure reliable
operation. Heat is removed by conduction, convection and
radiation to the surrounding environment. Increased airflow
enhances the heat transfer via convection. The available load
current vs. ambient air temperature and airflow at Vin=53 V
for each model is according to the information given under
the output section. The test is done in a wind tunnel with a
cross section of 305x305mm, the DC/DC converter vertically
mounted on a 8 layer PCB with a size of 254x254mm. Each
layer with 35 m (1oz) copper. Proper cooling can be verified
by measuring the temperature of selected devices. Peak
temperature can occur at position P1 and P2. The temperature
at these positions should not exceed the recommended max
values.
