Power resistors, rheostats (variable resistors), and other electrical loads are useful for testing power supplies and regulators. Though functionally equivalent to a mechanical rheostat, electronic ...
Designs requiring space-grade components must take into account the variances in component values that can occur over time. This is especially true for resistors, which can exhibit significant changes ...
Pickering Interfaces, has announced a family of one-slot PXI and PXIe programmable resistor modules that can handle 2A, 200V or 15W. Models 40-254 (PXI) and 42-254 (PXIe) come in 28 variants, ...
