LED Driver Testing
LED’s are a current driven DC device and require a converter so they can be powered from an AC voltage. These Power supplies for LED lighting are most commonly referred to as LED Drivers. LED Drivers have different operating characteristics from the typical AC to DC, and DC to DC Power Supplies used for most electronic equipment. They are often a constant Current output rather than a Constant Voltage Output. Chroma has created the industries first Electronic Load with an LED operating mode for simulating LED loading: the Chroma 63110A load module, for our 6310A series.
