The Agilent/Keysight E4367A is a modular Solar Array Simulator (SAS) mainframe that accurately reproduces the output characteristics of photovoltaic arrays under dynamic environmental conditions. Built on the E4360A mainframe with dual E4361A modules, this system delivers precise I-V curve simulation for testing inverters, power conditioning units, and satellite power systems. The E4367A excels at rapid I-V transients and maintains exceptionally low output capacitance—critical for validating real-time system responses without loading effects.
Technical Specifications
The E4360A mainframe occupies 2U of rack space and delivers up to 1200 W of output power at 200–240 VAC input (600 W at 100–120 VAC). Input range extends from 86 VAC to 264 VAC at 50/60/400 Hz, consuming a maximum of 2000 VA.
Each E4361A module provides 510 W maximum power with Voc Max of 65 V and Isc Max of 8.5 A. In fixed-voltage/current mode, output ranges from 0–60 V and 0–8.5 A. Programming accuracy reaches 0.075% + 25 mV for voltage and 0.2% + 20 mA for current (at 22°C ±5°C). Output ripple and noise measure 20 mV RMS / 125 mV p-p in simulator mode and 24 mV RMS / 150 mV p-p in fixed mode (20 Hz to 20 MHz bandwidth). Switching recovery time is less than 5 microseconds.
– Key Features
• Fast I-V curve changes with < 5 µs INH shutdown response and < 10 µs fault response on coupled outputs
• Very low output capacitance for minimal loading transients
• Dual-output configuration enables simultaneous multi-array simulation
• Over-voltage, over-current, and over-temperature protection
• SCPI-compliant command set for automated control
– Compatibility & Integration
Standard interfaces include LAN, USB, and GPIB. The 14360A System Control Tool software enables programming and synchronized operation of up to 100 SAS outputs in networked configurations. This architecture supports integration into production test floors, environmental chambers, and satellite power subsystem labs.
