eldoLED *2743X7 OPTOTRONIC 50W Constant Current 0-10V Dimmable LED Driver, Programmable Linear OTi50/120-277/DIM-1L AUX G2 (Osram 57456)

The OPTOTRONIC programmable and dimmable family includes efficient, linear, constant current LED drivers. OEMs can configure the output current in 1mA increments with one-click programming using the OPTOTRONIC programmer. Customers can also customize end-of-life indicators, LED thermal protection, and constant-lumen maintenance features. Programming doesn't require the driver to be powered up or connected to AC line voltage. These drivers offer built-in 0-10V dimming, with models ranging from true 1% to 10%, and an auxiliary output capable of powering various sensors.
