Agilent/Keysight 6256B DC Power Supply

The Agilent/Keysight 6256B is a 200 W DC power supply engineered for laboratory, industrial, and development applications requiring stable, regulated power. It delivers 0–10 V at 0–20 A with dual analog metering, coarse and fine voltage and current controls, and automatic CV/CC mode selection. The unit maintains 0.01% line, load, and metered regulation, making it suitable for device testing, circuit characterization, and precision measurement work.
