Keysight (Agilent) U8001A DC Power Supply, 30 V, 3 A, 90 W

The Keysight U8001A is a 90 W single-output DC power supply delivering 0–30 V at 0–3 A, designed for laboratory, manufacturing, and educational testing environments. It combines precise voltage and current regulation with low output noise and fast transient response, making it suitable for device characterization, bench testing, and development work. Non-programmable control via front-panel adjustment and three saved operating states enable straightforward operation without software configuration.

Built-in overvoltage and overcurrent protection safeguard connected equipment during test cycles.
