HP E4350B Solar Array Simulator, 60V, 8A

The HP One-Box Solar Array Simulator (SAS) is a dc power source that simulates the output characteristics of a solar array. The HP SAS is primarily a current source with very low output capacitance and is capable of simulating the I-V curve of different arrays under various conditions. The I-V curve is programmable over the IEEE-488.2 bus and is conveniently generated within the HP SAS.
