Please check out Keysight's newest, 5th-generation modular SAS solution - the MP4300A, which supports up to 6 kW of power in a 2U rack space.


Test Satellite Power Systems Under Various Conditions

Solar panels consisting of multiple solar cells provide power to satellites. They have unique I-V characteristics. The output power varies with environmental conditions (e.g., temperature, irradiation) and operational conditions (e.g., eclipse, spin). A specialized power supply, such as the solar array simulator (SAS), generates accurate outputs to verify the satellite power system.

  • 1200 W mainframe holds up to two modules
  • Small size: up to two outputs in 2 U of rack space
  • High output power: up to 600 W per output
  • Fast I-V curve change and fast recovery switching time
  • Easy to simulate environmental conditions
  • LAN, USB, and GPIB interfaces standard
  • Fully compliant to LXI (core) specification
  • Individual instrument or custom turn-key system

Small, Fast, and Flexible

The E4360 Modular Solar Array Simulator (SAS) is a dual output programmable dc power source that simulates the output characteristics of a solar array. The E4360 SAS is primarily a current source with very low output capacitance and is capable of quickly simulating the I-V curve of different arrays under different conditions.
