The Keysight N8944A Autoranging System DC Power Supply delivers 5 kW of stable DC power from a compact 3U rack-mount chassis. Operating from 360–440 VAC input, it provides 0–750 V and 0–20 A output at full 5000 W power, with autoranging capability that consolidates multiple traditional supplies into one unit. Programming accuracy reaches 0.1% for voltage and 0.2% for current, supported by built-in voltage and current measurement. Standard interfaces include LAN (LXI Core), USB, GPIB, and analog connections for rapid system integration into automated test equipment and laboratory environments. Integrated protection covers over-voltage, over-current, and over-temperature faults. Multiple N8944A units parallel via master/slave control to exceed 100 kW total output, managed as a single cohesive supply.
