DC Electronic Loads Catalog
产品目录
Keysight DC electronic loads are now offered in two capability classes across benchtop, ATE, and modular units. Benchtop DC electronic loads include the NL1-class, designed for fast, accurate, and reliable testing of power devices. ATE DC electronic loads include the NL3-class, providing a regenerative capability that efficiently returns up to 95% of the absorbed energy back to the grid. Modular DC electronic loads offer a flexible, scalable solution for testing a broad range of DC power sources by using a single mainframe that supports up to six configurable load modules.
Explore the DC electronic load families:
- Benchtop DC electronic loads come in one class, the NL1-class, and 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 web server and control software, 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.
- ATE DC electronic loads come in one class, the NL3-class, and include the EL4900 Series Regenerative Electronic Loads. They host a regenerative capability that efficiently returns up to 95% of the absorbed energy back to the grid. This feature provides operational advantages by reducing energy consumption and cooling costs. The series offers a wide power range, from 2 kW to 12 kW, in high-density 1U and 2U layouts, with the flexibility to easily parallel up to 16 units (up to 192 kW) to create a single electronic load system. The electronic loads include advanced features for precise testing, such as simultaneous digitized voltage and current measurements. These combined benefits enable power test engineers to reliably evaluate and accelerate test development across multiple environments, accelerating testing of batteries and other power devices under test (DUT), such as automotive electronics and avionics.
- Modular DC electronic loads offer a flexible, scalable solution for testing a broad range of DC power sources — including power supplies, batteries, converters, and fuel cells. Featuring a single mainframe that supports up to six configurable load modules, they deliver the precise voltage, current, and power levels needed for multichannel or high-power testing. Supporting multiple operating modes — constant current, voltage, resistance, and power — along with fast transient response and integrated measurement capabilities, these loads are ideal in bench and automated test environments.
