Absolute Maximum Ratings
Absolute maximums are stress ratings. Exposure of devices to
greater than any of these conditions may adversely affect long-term
reliability. Proper operation under conditions other than those listed
in the Performance/Functional Specifications Table is not implied nor
recommended.
Maximum Ratings Notes
The UEI-50/60W series does not include electronic Input Overvoltage
Protection. Therefore it is possible for the input to exceed the con-
tinuous ratings listed above and still operate. However, units are not
routinely Production-tested above the continuous ratings. Therefore,
the rated specifications do not apply at excessive input voltage and
performance is undetermined.
At some combinations of high ambient temperature, low airflow
or high output current, the controller may shut down from overtem-
perature if the maximum rated input voltage is exceeded.
The transient specifications indicate that sample lots were suc-
cessfully tested for 100 mS at the transient stress voltage and were
not damaged. As a practical matter in your application, it is often
difficult to determine how long an input overvoltage was applied.
Therefore, do not exceed the continuous voltage rating.
