The Keysight N8742A is a programmable DC power supply delivering 3300 W across a single output rated 600 V and 5.5 A. Built for automated test systems and precision laboratory applications, this 2U rack-mount unit combines high voltage capability with tight programming accuracy and low output ripple. Front-to-back airflow and compact form factor enable dense equipment configurations. Voltage and current measurement are built in. Full protection against overvoltage, overcurrent, overtemperature, and undervoltage conditions safeguard the load and supply.
The N8742A accepts universal AC input from 85 to 265 Vac, with factory-installed hardware options for single-phase 190–240 V or three-phase variants (208 V or 400 V). Programming accuracy reaches 0.05% + 300 mV on voltage and 0.1% + 11 mA on current. Output ripple measures 500 mV peak-to-peak and 120 mV RMS in constant-voltage mode.
Remote control and monitoring are standard via LAN (LXI-Core), USB, GPIB, and analog interfaces, supported by IVI-COM drivers and SCPI commands. A built-in web server enables browser-based access. Multiple units cascade in parallel (up to 4 identical units) for increased current or in series (up to 2 units) for higher voltage. Rear panel wire clamp connectors suit 150 V to 600 V operation.
