The Keysight Technologies (formerly Agilent / HP) E3630A is a compact and reliable 35-watt triple-output linear DC power supply. Designed specifically for benchtop manual testing, it provides low noise, stable output voltages, and built-in auto-tracking of the ±20V outputs to simplify circuit testing that requires balanced positive and negative voltages.
