Keysight N8755A DC Power Supply

Overview

The Keysight N8755A is a programmable single-output DC power supply delivering 30V and 170A (5.1kW) in a compact 2U package. Designed for automated test equipment (ATE) and high-current applications, it combines high power density with flexible connectivity and configuration options.

Features include front-panel operation with separate voltage and current knobs, built-in measurement of output voltage and current, and complete protection from overvoltage and overcurrent conditions. The N8755A supports parallel connection of up to four identical units for higher current or series connection for higher voltage, with airflow designed to allow direct stacking in ATE racks.
