# Keysight E3645A 80 W Single-Output Programmable DC Power Supply, 35 V/2.2 A or 60 V/1.3 A (Pre-Owned) # Keysight E3645A 80 W Single-Output Programmable DC Power Supply, 35 V/2.2 A or 60 V/1.3 A (Pre-Owned) ## Key Features At A Glance - Single and dual output models spanning 30 W to 100 W output power across the series - GPIB (IEEE-488) and RS-232 interfaces standard on every model for automated test systems - Selectable dual-range output for flexibility between higher voltage or higher current - 0.01% load and line regulation for steady output during power-line and load changes - Over-voltage protection adjustable from both the front panel and the remote interface - Remote sensing at the rear terminal eliminates load-lead voltage-drop errors - SCPI programming with VXI plug-and-play driver support, including Keysight VEE - Store and recall up to five complete instrument setups in non-volatile memory - Vacuum fluorescent display with rotary knob, front-panel binding posts and rear screw-type terminals - VXIplug&play instrument drivers for use with LabVIEW and LabWindows in addition to Keysight VEE - Cooling fan with automatic speed control for low acoustic noise The Keysight E364xA Series is a family of ten programmable DC power supplies offering output power from 30 W to 100 W in single- and dual-output configurations. The series delivers clean power, excellent regulation, and fast transient response, with built-in GPIB and RS-232 interfaces on every model. Each supply features a dual-range output, over-voltage protection, remote sensing, and save-and-recall functions for repeatable bench and system use. A DC power supply provides controlled, adjustable voltage and current to power a device under test. The E364xA Series is designed to meet the needs of R&D design verification, production testing, QA verifications, and other demanding applications, combining programmability with front-panel control for both engineering and automated environments. ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every used unit is inspected and functionally verified in-house by our technicians before it ships, while new units ship factory-sealed exactly as received from the manufacturer. That combination of held inventory and in-house verification lets us match the right instrument, in known condition, to your application. ## Brand Heritage This product line carries the heritage of a test-and-measurement business that traces its roots to Hewlett-Packard, founded in 1939. The test-and-measurement operations were spun off as Agilent Technologies in 1999, and in 2014 that business became Keysight Technologies, which carries the line forward today. ## Compare Other Models in This Series The Keysight E364xA Series comprises ten programmable DC power supplies that share a common design and deliver output power from 30 W to 100 W. All ten models provide clean power, excellent regulation, fast transient response, and built-in GPIB and RS-232 interfaces, and are designed for R&D design verification, production testing, QA verifications, and other demanding applications. Across the series, every model offers dual-range output, over-voltage protection, remote sensing, and save-and-recall of up to five setups, so the choice between models comes down to output configuration and power level rather than feature set. Each model in the series below is its own dedicated product page with condition-matched pricing. Select the pre-owned model that matches your required output configuration and power level, and review that page for its specific specifications and availability. The series divides into single-output models (E3640A through E3645A) and dual-output models (E3646A through E3649A). Single-output maximum power spans 30 W, 50 W, and 80 W, while the dual-output models provide 60 W or 100 W; the comparison table below lists each model's number of outputs, maximum power, DC output ratings, and physical dimensions. Models also differ by their dual-range output ratings — some pair an 8 V range with a 20 V range, while others pair a 35 V range with a 60 V range — and net weight varies accordingly. Refer to the comparison table to match a model's exact voltage and current ranges to your application.
