Agilent/Keysight 6205C DC Power Supply

The Agilent/Keysight 6205C is a dual-output DC power supply engineered for precision testing, development, and bench applications. Each output operates independently with selectable voltage ranges (0–20 Vdc or 0–40 Vdc) and corresponding current limits (0–0.6 A or 0–0.3 A). The supply delivers exceptional load and line regulation - both better than 0.01% + 4 mV - with low ripple and noise at 200 µV rms and 1 mV peak-to-peak.
