... Description The JAHW050A, JAHW075A and JAHW100A Power Modules are dc-dc converters that operate over an input voltage range of 36 Vdc to 75 Vdc and provide a precisely regulated dc output. The outputs are fully isolated from the inputs, allowing versatile polarity configurations and grounding connections. The modules have maxi- mum power ratings from 100 typical full-load efficiency of 90% ...

... Use Figure 33 to determine air velocity for the 1/2 inch heat sink. The minimum airflow necessary for the JAHW075A module is 0.5 m/s (100 ft./min.). 16 Custom Heat Sinks (continued) A more detailed model can be used to determine the (continued) required thermal resistance of a heat sink to provide necessary cooling. The total module resistance can be separated into a resistance from case-to-sink (θ ...
