The Keysight E4362A Solar Array Simulator DC Module is a 600 W power module engineered to accurately simulate solar array output characteristics for testing spacecraft power systems and satellite applications. Operating as a current source with very low output capacitance, it enables rapid I-V curve transitions to model diverse environmental conditions including temperature variations, aging, eclipses, and spin dynamics. The module supports two operational modes: direct parameter entry (Voc, Isc, Vmp, Imp) for internal I-V curve generation, or download of user-defined I-V curve tables for custom simulation profiles.
