Agilent/Keysight E36155AGV

The Keysight E36155A is an 800 W programmable DC power supply built for benchtop and automated test environments. This single-output instrument delivers 0–60 V and 0–40 A with autoranging architecture, enabling flexible V-I combinations within its maximum power envelope. Programming and readback accuracy of 0.03% + 10 mV on voltage and 0.1% + 10 mA on current ensure precise control and measurement.

Output noise remains low at less than 50 mV peak-to-peak and 5 mV rms (20 Hz to 10 MHz), with excellent line and load regulation throughout the operating range.
