The EA Elektro-Automatik line of benchtop programmable DC electronic loads come in desktop and tower formfactors and range in power from 300W up to 1500W. Select models have advanced features such as autoranging and a built-in function generator. The autoranging feature automatically adjusts current higher at lower voltages, and vice versa, to maintain full sinking power across a range of voltage/current levels. The function generator can provide many waveforms such as sine, triangle, rectangle, and trapezoid, and can also drive custom arbitrary waveforms for dynamic loading.
