About this file

This document outlines specifications for a Bidirectional DC Power Supply, modular electronic load modules, and modular electronic load mainframes required by the National Aeronautics and Space Administration Glenn Research Center. The Bidirectional DC Power Supply shall have a voltage rating of 600V, current rating of 40A, power rating of 6000W, two-quadrant operation for source and load functions, transient response below 1.5ms, optional CAN interface and auto sequencing programming, and low output noise and ripple. Twenty modular electronic load modules shall have a capacity of 300W each, operate across various modes including CC, CR, CV and CP, simulate capacitive loads, support multi-channel synchronous control, and have low voltage characteristics of 0.4V at 80A. Four modular electronic load mainframes shall each accommodate five load modules, include Ethernet interfaces, and support software capabilities. The related federal contract opportunity is solicited by the National Aeronautics and Space Administration Shared Services Center.
