The Keysight 6291A is a precision DC power supply delivering 0–40 V and 0–5 A across a 200 W output envelope. Designed for laboratory, production, and R&D environments, this half-rack instrument combines tight voltage and current regulation with low ripple performance and fast transient recovery. Auto-crossover operation transitions between constant voltage and constant current modes, while remote sensing and programmable control enable integration into automated test systems.
