Keysight / Agilent / HP 6573A Single-Output, 2000 W DC Power Supply

The Keysight 6573A is a single-output DC power supply delivering 2000 W of regulated power for benchtop and system integration applications. This unit combines front-panel and analog voltage/current control with fast transient response and low-noise outputs to support demanding laboratory and industrial test environments. Built-in protection features including CV/CC mode crossover and over-voltage protection safeguard connected devices. Fan-speed control minimizes acoustic noise while maintaining thermal stability across the full operating range.
