eldoLED *2743X3 OPTOTRONIC Programmable Linear 50 Watts Constant Current LED Driver, 0-10V Dimmable OTi50/120-277/1A4/DIM-1/L G2 (OSRAM 57452)

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 a built-in 0-10V dimming protocol with models available in true 1% to 10%. The auxiliary output has the capability to power various sensors.
