They also plan to finish up ongoing work to route power and data cables needed for new docking mechanisms that will be installed later. The voltage regulator, a 200-pound box known as a sequential shunt unit, or SSU, is one of eight at the base of each of the station's solar power wings that serve to relay regulated 160-volt DC current to...
