The Agilent/Keysight 6456B is an SCR-regulated DC power supply delivering 3600 W across a 0–36 VDC, 0–100 ADC output range. Built for moderate-regulation applications in electronic testing and development, it combines fixed and variable output capability with automatic constant voltage/constant current (CV/CC) crossover operation. Large, easy-to-read meters provide real-time voltage and current monitoring. The unit integrates inherent protection against overvoltage and overcurrent conditions, plus AC line dropout protection that automatically restores operation when input power returns to normal.
