The Agilent/Keysight 6111A is a 20 W DC power supply delivering precise voltage and current control across 0–20 Vdc and 0–1 A output ranges. Built for benchtop research, quality assurance, and automated test equipment systems, it combines exceptional load and line regulation with low ripple performance and front-panel programmability. The instrument operates in Constant Voltage or Constant Current limit modes, supported by remote programming, remote sensing, and auto-series/auto-tracking capabilities.
