Agilent/Keysight 6682A DC Power Supply

The Agilent/Keysight 6682A is a 5 kW single-output DC power supply engineered for high-current test applications in manufacturing and laboratory environments. GPIB-programmable with SCPI command support, it delivers 0–21 V at 0–240 A with low noise performance and precision regulation. Built-in voltage and current measurement, selectable inductive load compensation, and dual analog and digital control interfaces make it suitable for automated test systems requiring stable, repeatable power delivery.
