The Keysight 6673A is a single-output programmable DC power supply delivering 2100 W of regulated power across a 0–35 V, 0–60 A output range. Purpose-built for automated test equipment and research applications, it combines precise voltage and current programming with exceptionally low noise performance and fast transient response. GPIB and analog control interfaces enable seamless integration into test systems requiring deterministic power delivery and remote automation.
