Compact LED Ring Lights provide the high-power illumination required in machine vision, biomedical, fluorescence, and strobing applications. Each LED module contains four M3 mounting holes on a 29mm diameter circle. The universal power supply, which accepts a 90 - 245V AC input, ships with clip-on adapters for the US, Europe, and UK. Through the DIN rail mountable DC current controller, LED intensity can be adjusted manually via a potentiometer or by supplying a 0 - 5V analog control input. The DC current controller is designed to deliver up to 400mA at 24V.
