PDM Selection: What Should You Think About?

Register to learn guidance on the critical specifications or parameters that should be considered when developing or designing in a power distribution module.

Originally presented: October 14, 2020
Duration: 1 hour
Presented by:


Power distribution modules (PDM) at times are complex, multi-device circuit control and protection center that are centrally located in an application to provide safety, protection and ease of serviceability. PDMs centralize these functions and make maintenance easier by combining all the functions in a single accessible location.

Since PDM's can be complex, Littelfuse (on behalf of Waytek) would like to explain the key parameters and specifications that should be considered when developing or designing in a PDM.

Attendees will learn about defining a PDM, why they are important and what we consider are the most crucial requirements that should be considered when looking for a PDM. We will also offer recommendations on the rating and type of components used in a PDM. Application-specific requirements that affect the location and sizing of PDMs will be reviewed.

Selection of a PDM also requires an analysis of input/output requirements including wire routing, sizing and connection types to support the application. We will discuss the electrification of vehicles and how higher voltage requirements are affecting the basics of PDM design and selection.

Key Takeaways

  • Gain improved knowledge of the value-add that PDM's provide to application reliability and maintainability
  • Get a general understanding of PDM's and available components
  • Define key parameters required prior to selecting or designing a PDM
  • Learn what a PDM is, and what configuration options are available
  • Discover the importance of finding a trusted and knowledgeable partner
