The Agilent/Keysight E3645A is a programmable DC power supply for benchtop and system integration use, delivering stable, low-noise power across dual voltage and current ranges. Operating from 0 to 35 Vdc at 0–2.2 A or 0 to 60 Vdc at 0–1.3 A with a maximum power output of 80 W, this unit combines precision voltage and current control with automated test capability. Built-in GPIB and RS-232 interfaces support SCPI programming, enabling remote operation and integration into larger test systems.
