The Keysight E364xA Series is a family of ten programmable DC power supplies delivering 30 W to 100 W of output power in both single- and dual-output configurations. All models deliver clean power, excellent regulation, fast transient response, and built-in GPIB and RS-232 interfaces, combining solid performance with an accessible price point.

The series is designed to meet the needs of R&D design verification, production testing, QA verifications, and other demanding applications. A programmable DC power supply provides controlled, adjustable voltage and current to a device under test, serving as the foundational bench instrument for powering and characterizing circuits across the design, validation, and production cycle.

ValueTronics stocks and holds its own test-and-measurement inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, keeping units on hand and ready to ship. Every pre-owned unit is inspected and functionally verified in-house against the original manufacturer's specifications before it leaves our facility, while new units ship factory-sealed exactly as received.

Brand Heritage

The instrument's manufacturer traces its roots to Hewlett-Packard, founded in 1939. The test-and-measurement business was spun off as Agilent Technologies in 1999 and subsequently became Keysight Technologies in 2014, the name under which this series is offered today.

Compare Other Models in This Series

The Keysight E364xA Series comprises ten programmable DC power supply models spanning 30 W to 100 W of output power. Six models (E3640A through E3645A) are single-output supplies, while four models (E3646A through E3649A) are dual-output supplies, all sharing the same core architecture of dual-range output, over-voltage protection, remote sensing, and standard GPIB and RS-232 interfaces.

Across the family, the models differ primarily in maximum output power and in their dual-range voltage/current ratings. Every model offers two selectable output ranges, allowing each unit to trade higher voltage for higher current depending on the configured range.

Each model in the series below is listed as its own dedicated product page with pre-owned pricing matched to its condition. Select the specific model that fits your output power and voltage/current requirements to view its individual specifications and availability.

The single-output models step through three power tiers: the E3640A and E3641A are rated at 30 W, the E3642A and E3643A at 50 W, and the E3644A and E3645A at 80 W. The dual-output models pair into two tiers, with the E3646A and E3647A rated at 60 W and the E3648A and E3649A at 100 W. Within each pair, the models differ in their dual-range output ratings, with some pairs configured for lower-voltage/higher-current ranges (such as 0 to 8 V / 0 to 20 V) and others for higher-voltage/lower-current ranges (such as 0 to 35 V / 0 to 60 V).

Net weight and chassis height scale with output configuration, with the single-output models sharing one enclosure size and the dual-output models a taller one. The comparison table that follows lists each model's maximum power, number of outputs, DC output rating, and net weight so the correct tier can be matched to the application's voltage, current, and power needs.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.
