Ultra-Compact Standalone DC Electronic Load Device Supporting Broad DC Power Testing

Tektronix recently announced the Keysight Series 2380 product line, an ultra-compact standalone DC electronic load device that complements its complete set of power test and measurement solutions. The new DC electronic load device, supplied in 200W, 250W, and 750W models, offers flexibility, superior performance, and competitive pricing to handle a wide range of applications including performance verification, stress testing, and environmental testing of DC power sources, power components, and batteries in the power electronics, LED lighting, battery research, automotive, and alternative energy sectors.

Electronics engineers or test engineers developing or testing DC power supplies or batteries can use a DC E-LOAD to easily and quickly simulate real loads to verify device performance under various conditions. The new 2380 DC electronic load device series features various operation modes and automatic test modes that provide dynamic load cycling at up to 25 kHz, excellent voltage/current resolution and readback accuracy, and selectable multiple interfaces.

Michael Ewald, senior director of Tektronix's related product line, stated, "In developing this DC E-LOAD product line, it became clear that engineers are looking for products that offer economic pricing while delivering precision and performance. The 2380 series provides the best value in the DC electronic load device sector, and when used with Tektronix's power analyzers, power supplies, SMUs, DMMs, and oscilloscopes, it enhances the capabilities of comprehensive and cost-effective benchtop test solutions for all types of power conversion device testing."

Engineers can use the 2380 series models to test devices in various operating modes using the same instrument. Operating modes include CC (constant current), CV (constant voltage), CR (constant resistance), and CP (constant power). The new instrument provides high reliability with 0.1mV/0.01mA voltage/current readback resolution and 0.025%/0.05% voltage/current readback accuracy in measurement accuracy.

Other features include a built-in CR-LED test function that can simulate actual LED lamps or LED strings,
and provides integrated functionality for easily measuring the rise/fall time of DC power source voltages. Additionally, it simplifies testing and monitoring of inrush currents from the DUT and provides a list mode that enables convenient generation of wide-ranging load current variations.
