Keysight E4361A/J01 Solar Array Simulator Module

Overview

The Keysight E4361A/J01 is a 498W solar array simulator (SAS) DC power module with the J01 configuration option. Designed to replicate the output characteristics of solar arrays, this module operates as a current source with minimal output capacitance, enabling rapid I-V curve modifications to accurately simulate different solar arrays under varied environmental conditions such as temperature changes, aging, eclipse effects, and thermal spin. The J01 option modifies the electrical characteristics to 58V maximum, 9.3A maximum, and 498W total power.

Key Features

• 498W maximum output power (J01 configuration)
• 58V maximum open-circuit voltage (Voc) — J01 modified
• 9.3A maximum short-circuit current (Isc) — J01 modified
• Minimal output capacitance for current-source operation
• Fast I-V curve changes for accurate solar array simulation
• Two operational modes: parameter input (Voc, Isc, Vmp, Imp) or user-defined table download
• Modular design compatible with E4360A mainframe (accepts up to 2 modules per mainframe)

Specifications

• Output voltage (fixed mode): 53.5V rated; 9.3A rated at 220/240 VAC, 4.65A at 100/120 VAC
• Ripple and noise (20Hz-20MHz): voltage 20mV RMS / 125mV p-p (simulator/table mode), 24mV RMS / 150mV p-p (fixed mode)
• Current ripple and noise (20Hz-20MHz): 2.5mA RMS / 19mA p-p

Applications

• Satellite power system testing with modified voltage/current requirements
• Solar panel and array characterization
• Photovoltaic system development and simulation
