Non-isolated Full Power Breaker

 

High-Power Local Port Programmable Non-Isolated Circuit Breaker

          Each of the six low-voltage ports have power distributed to them by the observatory.  This is done by six circuit breakers; one for each user experiment.  The circuit breaker provides 48VDC at eight programmable trip levels.  This module is a hardware dependent item and thus is selected prior to deployment.  Since this breaker is not isolated, it can potentially supply a large portion of the total bus power to this single user.   The maximum power allocated to this breaker is yet to be determined and will be programmed in eight steps.
