Models 40-251 (2.5W), 40-252 (5W) and 40-253 (10W) are aimed at applications that require accurate medium-power programmable resistance such as a programmable load for the testing of electronic control units (ECUs) in automotive, military and aerospace sectors, as well as level sensing.

Available in modular PXI format for system integration, the resistor modules are compatible with a wide range of chassis, including PXI, PXIe Hybrid, cPCI and Pickering USB/LXI chassis.
