Agilent/Keysight 6205B DC Power Supply

The Agilent/Keysight 6205B is a dual-output benchtop DC power supply engineered for laboratory and production testing environments. Each of its two independent, floating outputs delivers regulated power in selectable ranges: 0–20 VDC at 0.6 A or 0–40 VDC at 0.3 A, for a combined 20 W total output. The instrument combines precise voltage regulation with current-limiting protection, backed by low noise performance and exceptional load/line stability across operating conditions.
