The Keysight/Agilent/HP 6542A is a 200 W single-output programmable DC power supply engineered for stable, low-noise power delivery in benchtop and automated test environments. It delivers 0–20 V and 0–10 A at 40°C with fast transient response and integrated protection features including overvoltage, overcurrent, and thermal safeguards. Front panel and analog programming interfaces enable flexible control without requiring GPIB connectivity.
