Technical Reference Notes

AEH25B48 HS Adapted

AEH25B48 Isolated DC/DC Converter Module

Industry Standard ½ Brick – 36-75V Input, 12V / 25A Output

The AEH25B48 is Astec’s latest addition to its Ultra High Density ½ Brick family capable of delivering 300W of full power at

12V - 25A of load current. With efficiencies of 92.7% typical plus the standard features common to the AEH half brick series,

this version is best suited not only for 12V applications but for Intermediate Bus Voltage Applications as well.

ABSOLUTE MAXIMUM RATINGS

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation

of the device is not implied at these or any other conditions in excess of those given in the operational sections of the

specs. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
