eldoLED | 2743W5 OPTOTRONIC OTi 85W Programmable Linear LED Drive | Replacement for Osram 57420 | Oti85/120-277/2A3/DIM-1 L

eldoLED 2743W5 OPTOTRONIC OTi 85W Programmable Linear LED Driver — Direct OSRAM 57420 ReplacementProfessional-grade 85W LED driver engineered for architectural lighting systems. The OTi 85W delivers synchronized dimming control, true 1% output precision, and constant lumen maintenance to preserve light quality throughout fixture lifetime.Key Features:Synchronized ON/OFF and dimming across multiple luminaires ensures uniform light levels and meets energy code requirements.True 1% dimming maintains precise output current across the full programmable range — program to 300mA and dim to just 3mA for maximum control flexibility.DIM-to-OFF transition eliminates the need for external control equipment, reducing installation complexity and energy consumption.Dimming interface protection guards against AC line voltage (120-277Vac) mis-wiring with visual error indication for field technicians.Constant lumen maintenance automatically adjusts LED drive current to compensate for lumen depreciation, maintaining required brightness levels over the fixture's operational life while optimizing energy efficiency.Programmable AUX power output extends DIM-to-OFF capability to integrated sensors and controls.Input: 120-277Vac. Output: 2A3 configuration. Model: *2743W5 57420-Oti85/120-277/2A3/DIM-1 L.Direct replacement for OSRAM 57420 drivers. Ideal for retrofit and new construction projects requiring reliable, code-compliant dimming performance.
