Absolute Maximum Ratings:
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute
stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those
given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can
adversely affect the device reliability.

CAUTION: This power module is not internally fused. Both A & B feeds and their corresponding
returns must be individually fused.
To preserve maximum flexibility, internal fusing is not included. However, to achieve maximum safety and system
protection, the safety agencies require a fast-acting fuse with a maximum rating of 15 Amps and Voltage Rating >/=
75Vdc for the
–48AF, -48BF VRTN_AF & VRTN_BF feeds. Consult Fusing and fault protection (Section 4.1.4) of
PICMG 3.0 ATCA specifications for additional information. Based on the information provided in this data sheet on
inrush current and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the
fuse manufacturer’s data sheet for further information.
