eldoLED 2743X3 (Osram 57452) OPTOTRONIC OTi50/120-277/1A4 DIM-1L G2 50W Constant Current, 0-10V Dimmable LED Driver

The OPTOTRONIC programmable dimmable family consists of highly efficient, linear, constant current LED drivers. One click programming through the OPTOTRONIC programmer allows OEMs to configure the output current with 1mA resolution. The end-of-life indicator, LED thermal protection, and constant lumen maintenance features are also fully customizable by customers. The OPTOTRONIC programmer does not require the driver to be powered up or connected to AC line voltage while programming. The power supplies are available with built-in 0-10V dimming protocol with models available in true 1% to 10%. The auxiliary output has the capability to power various sensors.
