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 20 Amps and Voltage Rating >/= 75Vdc for the –48AF, -48BF

VRTN_AF & VRTN_BF feeds. Consult Fusing and fault protection Section 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.
