EN/LZT 146 79 R1B Ericsson Power Modules AB, March 2004
NOTES:
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
respectively. Absolute max continuous input
voltage is 80 V dc.
2)
The power modules will operate down to
35V, when VI decreases, but will turn on 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 unspecified
manner.
