transformer isolated power supply, T < 40° C
A coldplate or a heatsink in an environment with sufficient airflow can be used to achieve the above drive ratings.
For temperature operation beyond the standard 0-40° C range, above-listed ratings may change. Contact your PMD
representative for additional information on Atlas extended temperature operation including higher temperature drive
ratings.
