The Keysight N5748A is a single-output, 760 W system DC power supply engineered for automated test equipment and general-purpose laboratory power applications. It delivers 0–80 Vdc at 0–9.5 A with programmable voltage and current, operating in both constant voltage (CV) and constant current (CC) modes. The unit combines a compact 1U rack-mount form factor with universal AC input (85–265 VAC), LXI Class C compliance, and standard GPIB, LAN, and USB interfaces for seamless integration into networked test systems. Built-in measurement, comprehensive protection features, and remote enable/disable functionality make it suitable for high-reliability ATE environments requiring flexible power delivery and precise load simulation.
