The Keysight E4360A is a two-slot modular solar cell simulator (SAS) for rapidly simulating the IV curves of various arrays under various conditions (eg, temperature, age, etc.).
The mainframe is already optimally preconfigured with 2 DC modules E4361A. Each solar cell simulator module E4361A has 65V, 8.5A, 510W.
Alternatively, you can get the E4360A mainframe with 2 DC modules E4362A (E4368A) or without modules.
