The Keysight E4360A is a modular solar cell simulator (SAS) with two slots for quickly simulating the I-V curves of different arrays under different conditions (e.g. temperature, age, etc.).
The mainframe is available here already optimally preconfigured with 2 E436*A modules of your choice.
You can choose from:
E4361A | Solar Array Simulator DC Module 0-65 V, 8.5 A, 510 W
E4362A | Solar Array Simulator DC Module 0-130 V, 5 A, 600 W
Alternatively, you can also get the E4360A mainframe with 2 DC modules E4361A (E4367A), with 2 DC modules E4362A (E4368A) or without modules.
