E3649A

Keysight Technologies (Agilent HP)Agilent HP

The Keysight (Agilent) E3649A is a high-performance, dual-output, 97W programmable DC power supply designed for both benchtop use and system integration. Part of the popular E3640 series, it provides clean, low-ripple power with dual output ranges up to 35V/1.4A or 60V/0.8A per channel. Complete with GPIB and RS-232 interfaces, it features Standard Commands for Programmable Instruments (SCPI) support, excellent regulation, and dual-line vacuum fluorescent displays, making it ideal for general-purpose electronic test and R&D environments.
