	Power distribution and control module

Power distribution and control modules by Southwest Research Institute (SwRI) provide mission critical power switching of external loads as well as solar array switch control and power bus monitoring.

Our power distribution modules have flown on or are in development for the following missions:

• IMAGE

• Swift

• Deep Impact

• Orbital Express

• Kepler

• WISE

Capabilities Provided by SwRI Power Distribution Models
