Standalone DC electronic loads aid power-delivery testing

January 27, 2016 // By Graham Prophet
The Keithley (Tektronix) Series 2380 supports DC power test applications including power electronics, LED lighting, battery research, automotive, and alternative energy.

Joining Keithley’s power test and measurement offering, and available in 200W, 250W and 750W models, the DC electronic loads can handle a range of applications including performance verification, stress test and environmental test of DC power sources, power components and batteries.

DC electronic loads simulate real-world loads; the Series 2380 features multiple operation modes and auto test modes with up to 25 kHz dynamic load cycling mode, superior voltage/current resolution and read back accuracy and multiple interface choices. Tektronix comments, "The Series 2380 represents the industry's best value in a DC electronic load, and along with our power analysers, power supplies, SMUs, DMMs and oscilloscopes rounds out our comprehensive and cost-effective bench test solution for all types of power conversion device testing."

Using any of the Series 2380 models engineers can test their device under multiple working modes using the same instrument. The operation modes include constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CP). The new instruments offer measurement accuracy of 0.1 mV/0.01 mA voltage/current read back resolution and 0.025%/0.05% voltage/current read back accuracy.

Other features include: a built-in CR-LED test that can simulate real LED lamps or LED strings; integrated facilities for measuring the voltage rise/fall time of DC power sources; an I-Monitor function that simplifies testing/monitoring of current drawn from the DUT; list mode making it easier to create a wide range of load current changes; and a battery test function that simplifies battery life and capacity testing.
