63110A LED Load Operating Instructions Demo

Chroma has created the industries first LED simulator for LED driver testing with our 63110A/13A electronic load modules. These DC Load Modules overcome problems found in using other mfg’s E-Loads or LED’s for testing drivers. Most E-Load manufacturers have similar designs but are unable to simulate the I-V curve of the LED as well as internal capacitances causing abnormal OCP, OVP. Therefore, other E-Loads are...
