Ultra-high integration, 4U chassis with up to 16 channels
NXI-3201 DC Programmable Electronic Load Cards can be integrated with NXI-F1080 and other chassis, supporting up to 16 channels in a single device. Each channel is electrically isolated. It can be controlled separately or simultaneously. The ultra-high integration in multi-channel batch test system applications reduces test cost and instrument occupation for users.

LED light simulation to test LED driving power
The electronic load has LED light simulation function. As shown in the figure, the LED equivalent circuit is to connect the resistance Rd with the voltage source Vf in series. Its I-V curve is equivalent to tangent of the real LED nonlinear I-V curve at the operating point (Vo, Io). With built-in LED mode, NXI-3201 boosts efficient testing of LED power supplies

OCP (over current protection) test
During OCP test, NXI-3201 will load under CC mode and check whether the DUT voltage is lower than end voltage. If lower, NXI-3201 will record the present loading current as the test result and shut the input to stop the test. If the DUT voltage is higher than end voltage, NXI-3201 will increase the loading current until the DUT voltage is lower than end voltage or it reaches the Max. loading current.
