Agilent/Keysight E36155A

The Keysight E36155A is an 800 W autoranging DC benchtop power supply engineered for precision testing, design validation, and quality assurance. This single-output instrument delivers 0–60 V and 0–40 A with programmable voltage and current control, supported by tight accuracy specs and advanced protection. Autoranging capability maximizes power delivery across the full voltage-current envelope, while peak power handling up to 2400 W accommodates transient load spikes and inrush currents.
