75 Watt User Power Breaker

 

75 Watt Local Port Programmable 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. The 75 watt module provides up to 1.5 amps in 0.1875 amp steps.
