The Keysight N5746A is a programmable DC power supply delivering 40 V at 19 A (760 W) in a compact 1U rack-mount chassis. This single-output instrument provides stable DC power with built-in voltage and current measurement, serving a broad range of bench and automated test applications. Front-panel digital controls, analog programming inputs, and remote interfaces enable flexible system integration. Comprehensive protection circuits guard against over-voltage, over-current, and over-temperature faults, while selectable under-voltage limiting provides additional safeguards.
