The Agilent/Keysight E3644A is an 80 W single-output linear DC power supply engineered for benchtop R&D, production testing, and quality assurance applications. Dual-range output capability delivers 0–8 V at 8 A or 0–20 V at 4 A, with exceptional regulation, low noise, and fast transient response. Front-panel binding posts and rear screw terminals accommodate diverse lead configurations. Remote sensing and overvoltage protection are standard. Programmable via GPIB and RS-232 with full SCPI support and stored setups for up to five configurations.
