Keysight (Agilent) N5749A System DC Power Supply, 100 V, 7.5 A, 750 W

The Keysight N5749A is a single-output, 750 W DC power supply engineered for automated test systems, product development, and manufacturing environments. It delivers stable power across 0–100 V output voltage and 0–7.5 A output current, with line and load regulation both held to ≤0.1% of setting. Output ripple and noise measures ≤1 mVrms (20 Hz to 20 MHz), ensuring clean power delivery to sensitive loads.

Programming and readback accuracy specifications support precision voltage and current control, while fast transient response (<500 µs for 10% load changes) accommodates dynamic load conditions.
