Agilent/Keysight 6268B DC Power Supply

The Agilent/Keysight 6268B is a precision DC power supply engineered for laboratory and production environments requiring stable, programmable power delivery. It supplies 0–40 V DC and 0–30 A DC with approximately 1.2 kW output capacity, supporting both constant voltage and constant current modes. Analog programmable control via external resistance or DC voltage enables remote operation, while remote sensing ensures accurate regulation at the load terminals. The instrument delivers load regulation of 0.01% + 200 µV in CV mode and 0.02% + 2 mA in CC mode, with transient recovery under 50 µs. Output ripple and noise remain below 1 mV rms in CV operation and 20 mA rms in CC mode across the 20 Hz to 20 MHz bandwidth.
