• Manufacturer Part Number: dw025
• Description: Dw025 Dual Output-series Power Modules Dc-dc Converters
• Manufacturer: Lineage Power

DW025 Dual Output-Series Power Modules: dc-dc Converters;
36 Vdc to 75 Vdc Input; Dual Outputs; 25 W
Thermal Considerations
Note: Dimensions are in millimeters and (inches). Drawing is not to scale.
The 25 W dual output power modules are designed to
operate in a variety of thermal environments. As with
any electronic component, sufficient cooling must be
provided to help ensure reliable operation of the unit.
Heat-dissipating components inside the module are
thermally coupled to the case. Heat is removed by con-
duction, convection, and radiation to the surrounding
environment.
