Keysight E4361A Solar Array Simulator DC Module

Overview

The Keysight E4361A is a 510W solar array simulator (SAS) DC power module designed to replicate the output characteristics of solar arrays. Operating primarily as a current source with minimal output capacitance, it enables rapid I-V curve modifications to accurately simulate different solar arrays under varied environmental conditions including temperature changes, aging, eclipse effects, and thermal spin.

Key Features

• 510W maximum output power
• 65V maximum open-circuit voltage (Voc)
• 8.5A maximum short-circuit current (Isc)
• 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)
• Standard measurement capabilities for voltage and current

Specifications

• Output voltage range: 0-60V (fixed mode), up to 65V (simulator mode)
• Output current range: 0-8.5A
• Programming accuracy at 22°C±5°C: voltage 0.075% + 25mV, current 0.2% + 20mA
• 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 and validation
• Solar panel and array characterization
