Agilent/Keysight 6274B DC Power Supply

The Agilent/Keysight 6274B is a 900 W linear DC power supply engineered for precision testing and measurement across laboratory, R&D, and industrial environments. It delivers stable voltage and current outputs with constant voltage/constant current (CV/CC) operation, automatically transitioning between modes to maintain consistent power delivery under varying loads. The instrument combines low-noise performance with comprehensive protection and remote sensing capability, making it suitable for sensitive electronic applications requiring minimal interference.
