High power range with specialized capabilities
Keysight Expert benchtop DC power supplies come in two classes. The NB1-class includes the E36150 Series, and the NB2-class includes the E36300 Series. They provide precise voltage and current control with a maximum output up to 800 W. Our highest power Expert model provides autoranging capabilities up to 800 W, ideal for testing motor drivers, power inverters, and DC to DC converters that require high voltage or current underload. Keysight Expert DC power supplies include all the capabilities in our Advanced models with additional features like enhanced programming speed, automotive ISO preset library, playback simulation, and e-logging features. Choose one of our popular configurations or configure one specific to your application.
Elevated data logging
Record and analyze power output over time, creating traceable reports for verification and compliance purposes.
LIST mode programming

Frequently asked questions
Multi-output power supplies can provide power to several devices at once, making them ideal for testing circuits that require different voltage levels or multiple power rails.
Single-output power supplies offer a single, fixed output, which is perfect for straightforward applications that require only one voltage or current level.
Multi-output models are more flexible and space-efficient for complex testing setups, while single-output models are simpler and cost-effective for basic testing needs.
Advanced data logging allows you to record and analyze power output over time. It makes it easier for you to track the performance of your DUT throughout long-duration tests. Whether you are monitoring voltage stability, current fluctuations, or other parameters, data logging provides detailed insights that help with debugging, optimization, and performance verification.
With LIST mode programming, you can create complex output sequences with customizable voltage and current steps. This feature is valuable for simulating real-world scenarios where the power supply needs to change over time in a predictable manner. LIST mode programming makes it easy to automate the process of changing output values during testing. This helps you reduce setup time and increase test efficiency, especially for tasks like device stress testing or battery simulation.
The adjustable slew rate allows you to control the rise and fall times of voltage and current during testing. This is particularly useful for simulating real-world conditions where devices may not experience instantaneous voltage or current changes. It helps prevent inrush currents and other issues that can affect sensitive components, ensuring your tests match specific requirements, whether for gradual startup sequences or power cycling simulations.
