Agilent/Keysight 6218C DC Power Supply

The Agilent/Keysight 6218C is a single-output DC power supply delivering stable, low-noise power for bench testing and measurement applications. It operates in both constant voltage and constant current modes with automatic load-dependent transitions, providing 0–60 V at 0–5 A output. Ten-turn controls enable precise voltage and current adjustment, while a front-panel volt/ammeter with selectable display monitors real-time output parameters.
