The Keysight N5743A is a 750 W single-output programmable DC power supply engineered for automated test and device characterization. It delivers up to 12.5 V and 60 A with constant voltage/constant current operation, programmable via analog (0–5 V or 0–10 V) or resistance (0–5 kΩ or 0–10 kΩ) inputs. Output noise is as low as 8 mVrms, with built-in voltage and current measurement. Comprehensive protection includes over-voltage, over-current, and over-temperature safeguards.
