*2743W3 OPTOTRONIC 55W Constant Current 0-10V Dimmable LED Driver, Programmable Compact OTi55W/120-277/2A0/DIM-1 - Replacement/Compatible with Osram 57355

eldoLED *2743W3 OPTOTRONIC 55W Constant Current 0-10V Dimmable LED Driver, Programmable Compact OTi55W/120-277/2A0/DIM-1 The eldoLED *2743W3 OPTOTRONIC 55W Compact Driver boasts features that enhance the architectural lighting design, including true 1% dimming across their entire output range, offering designers flexibility and precision. They ensure synchronized ON/OFF timing and consistent dimming across multiple luminaires, meeting efficacy requirements. The DIM-to-OFF feature allows for smooth transitions, and an AUX power output, supports fixture-integrated sensors and controls. OEMs can customize these programmable features efficiently with the one-click OPTOTRONIC Programmer, which doesn't require a power supply connection to AC line voltage during programming.
