The Agilent/Keysight 6264B is a constant voltage/constant current (CV/CC) DC power supply delivering 0–20 VDC at 0–20 ADC with 600 W output capacity. Built around a transistor series-regulator and triac-preregulator topology, it provides stable output with exceptional regulation and minimal ripple for demanding test, development, and laboratory applications. Though discontinued by Keysight, the 6264B remains a functional platform for electronics repair, precision power delivery, and bench-level system integration.
