DC Power Supplies Catalog

DC Power Supplies Catalog

Catalogs

This Catalog provides a comprehensive overview of DC sources designed for accurate power delivery, precise voltage and current control, and automated test workflows in R&D labs and production environments. Organized into Essential, Advanced, Expert, and Pro performance grades, the catalog covers benchtop supplies, ATE system supplies, modular DC solutions, and specialty power systems that support a broad range of applications. Engineers can choose compact benchtop units for education and design benches, autoranging and high‑current supplies for device characterization, high‑power ATE supplies for automated system test, and specialty systems for battery emulation, photovoltaic array simulation, and EV powertrain validation.
 

Benchtop DC supplies provide stable, adjustable power with low ripple/noise and optional sequencing capabilities to support consistent measurements. Across the grades, Keysight offers models ranging from entry‑level triple‑output instruments to high‑performance, low‑noise sources for sensitive device work.
 

ATE system power supplies deliver high power density and rapid command response for automated test, with autoranging outputs, regenerative options, multi‑kilowatt scalability, and hardware‑based real‑time control for reduced test times and efficient rack utilization. Modular DC solutions allow users to create application‑specific power systems by combining mainframes with more than 35 module types, including precision, high‑performance, SMU, and electronic load modules, tailoring setups for general‑purpose, photovoltaic, and battery‑cell testing. Specialty power solutions extend capabilities into domain‑specific applications, such as battery emulation with integrated profiling, photovoltaic array simulation for solar inverter test, HEV/EV power converters with bidirectional power, and mobile communication DC sources optimized for low‑noise RF testing.
 

Keysight software and accessories enhance these power supplies with remote control, data logging, automated sequencing, battery and PV workflows, IV curve measurement, and lab management tools. Accessories such as Kelvin probes, ultra‑low‑noise filters, interface modules, cable kits, and rack‑mount hardware help ensure accuracy and smooth integration into test environments.
 

Explore the DC power supply performance grades:

  • Essential benchtop DC power supplies come in the NB1‑classwhich includes the EDU36311A. They deliver 90 W maximum power, 5 A per output, and 30 V maximum voltage. Essential models provide high accuracy with low noise, tight line/load regulation, built‑in protection, and a 7‑inch color display for simultaneous control/visibility of three independent outputs. They are ideal for teaching labs and general‑purpose prototyping, with straightforward remote connectivity for control and automation.
