1)
The input voltage range 36…75 V dc meets
the European Telecom Standard prETS
300 132-2 Nominal input voltage range
in 48 V and 60 V dc power systems,
–40.5…–57.0 V and –50.0… – 72.0 V respec-
tively. Absolute max continuous input voltage
is 80 Vdc.
2)
The power module will operate down to
≤ 35V, when VI decreases, but will turn on to at
VI
≤ 36V, when VI increases
(see also Operating information).
Stress in excess of Absolute Maximum
Ratings may cause permanent damage.
Absolute Maximum Ratings, sometimes
referred to as no destruction limits, are
normally tested with one parameter at a
time exceeding the limits of Output data or
Electrical Characteristics. If exposed to stress
above these limits, function and performance
may degrade in an unspecied manner.
Absolute Maximum Ratings
Input TC < TCmax unless otherwise specied
