Absolute Maximum Ratings, sometimes referred to as no destruction limits, are normally tested with one parameter at a time exceeding the limits of Output data or Electrical Characteristics. If exposed to stress above these limits, function and performance may degrade in an unspecified manner. cui.com For more information, please visit the product page.

These modules can be operated in parallel rallel for current sh sharing or redundancy applications by tying the respective e together on dedicated power and ground copper planes. Sharing within 5% inputs and outputs of each module of full load rating can n be expecte expected between etween m modules. To optimize module performance, care should be taken put and ou ed to maintain equal input output impedance paths for each module. If one or more modules connected to a ed, the other mo common load is disabled, modules will automatically pick up the load provided that the rated power aining m e is not exc of each remaining module exceeded. cui.com For more information, please visit the product page.
