The Keysight E4360A is a modular solar array simulator mainframe that generates precise I-V curves for photovoltaic testing under simulated environmental conditions. This 2U chassis accepts up to two E4360 series modules (sold separately) and delivers 1200 W maximum output from 200-240 VAC input, or 600 W from 100-120 VAC input. The instrument functions as a current source with very low output capacitance, enabling rapid transient response and accurate characterization across eclipse, temperature, age, and spin scenarios.
