The bench electronic load reinvented
Keysight NL1-class benchtop DC electronic loads include the EL30000 Series Bench Electronic Loads. They are designed for fast, accurate, and reliable testing of power devices. With a compact design and intuitive display, they offer precise control of voltage, current, and power to simulate real-world conditions. Built-in features, multiple test modes, and an oscilloscope-like view — plus high-accuracy measurements (±0.04%) — enable detailed analysis of device performance. Select the right model based on power, current, voltage, and input channels to test power supplies, batteries, LED drivers, and other components. Choose one of our popular configurations or configure one specific to your application.
Multiple test modes
Simulate real-world operating conditions with four test modes: constant voltage (CV), constant current (CC), constant resistance (CR), and constant power (CP).
Oscilloscope-like viewer
Built-in waveform viewer that provides real-time oscilloscope-like visualization of voltage, current, and power signals directly on the screen.
Intuitive touchscreen
Features a high-resolution 4.3-inch color touchscreen that enables quick navigation, easy parameter entry, and real-time data visualization.
Remote operation
A built-in web server and control software enable remote operation, test sequencing, data logging, and easy integration into automated test systems.

Frequently asked questions
A benchtop DC electronic load is a type of electronic load designed for use on a workbench or desktop. It's typically a compact and self-contained unit that provides a variety of functions for testing and characterizing DC power sources. Benchtop loads are often designed with user-friendly interfaces, making them easy to set up and operate. They may have features like digital displays, intuitive menus, and remote control capabilities.
Benchtop loads are ideal for general-purpose testing, lower power applications, and situations where portability and cost-effectiveness are important. Benchtop DC electronic loads are compact and contained, measure a lower power range, and are designed for ease of use.
Mainframe and modular electronic loads are generally best suited for high-power testing, complex test setups, and applications requiring flexibility and scalability. They consist of a mainframe chassis that houses multiple load modules.
Ultimately, consider your power requirements, testing needs, budget, and desired features when selecting a DC electronic load.
Like other DC electronic loads, benchtop models offer a range of features, including:
- Multiple operating modes: constant current (CC), constant voltage (CV), constant power (CP), and constant resistance (CR) modes allow for simulating different load conditions.
- Adjustable parameters: users can precisely control the load current, voltage, or power levels.
- Accurate measurements: many benchtop loads include built-in measurement capabilities for monitoring voltage and current.
- Programmability: some models offer programmable functions for automated testing and custom load profiles.
- Remote control: interfaces like USB or LAN allow for remote control and integration into test systems.
- Protection features: built-in protection mechanisms prevent damage from overvoltage, overcurrent, and overtemperature conditions.
Benchtop DC electronic loads are used in a variety of DC power applications, such as:
- Power supply testing: characterizing power supply performance, including voltage regulation, current limiting, and transient response.
- Battery testing: evaluating battery capacity, discharge characteristics, and cycle life.
- LED driver testing: testing the performance and efficiency of LED drivers.
- Component testing: simulating loads for various electronic components.
- General electronics: providing a controlled and adjustable load for various testing needs in electronics labs and production environments.
