The Keysight E3641A is a 30 W single-output DC power supply engineered for benchtop R&D, production testing, and quality assurance. Its dual-range architecture delivers 0–35 Vdc @ 0–0.8 A or 0–60 Vdc @ 0–0.5 A, enabling flexible power delivery across diverse load conditions. With line and load regulation better than 0.01% + 3 mV (voltage) and transient response under 50 µsec, this supply maintains exceptionally clean, stable output. Voltage ripple and noise measure < 8 mVpp / 0.5 mVrms; current noise stays below 4 mArms.
