Aplab SAS12010 Modular Solar Array Simulator is a programmable DC Power Source that simulates output characteristics of a solar array. Model SAS12010 is primarily a current source with very low output capacitance and is capable of simulating I-V curve of solar arrays under different conditions like temperature, irradiance etc. SAS is supported with intelligent front-end software that simulates any curve with Voc, Isc, Vmp, Imp parameters or manually programmed points.
