dc025 Lineage Power, dc025 Datasheet - Page 2

• Manufacturer Part Number: dc025
• Description: Dc025 Dual-output-series Power Modules
• Manufacturer: Lineage Power

18 Vdc to 36 Vdc Input; 25 W
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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 device reliability.
Electrical Specifications
Note: Two pinouts are available for the DC025 Dual-Output-Series Power Modules. The DC025AJ-M, AB-M,
Unless otherwise indicated, specifications apply to all modules over all operating input voltage, resistive load, and
temperature conditions.

Fusing Considerations
CAUTION: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fus-
ing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The
safety agencies require a normal-blow, dc fuse with a maximum rating of 5 A (see Safety Considerations section).
Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same
type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data for further information.

BK-M, and CL-M Power Modules, which have both positive and negative outputs, have a common output
ground pin (pinout A). The DC025AA-M, AB-M, AF-M, BB-M, and CC-M Power Modules, which have dual
positive outputs, have separate output ground pins (pinout B). See Outline Diagrams section.
