OTi75W/120-277/2A0/DIM-1/J

The eldoLED OPTOTRONIC OTi75W/120-277/2A0/DIM-1/J is a high-performance, compact programmable constant current LED driver designed for commercial and architectural lighting applications. Delivering up to 75W of output power with a programmable current range of 700–2000mA (factory default 2000mA), this driver ensures precise, flicker-free illumination for LED downlights, troffers, and wall wash fixtures. Its 0–10V dimming capability allows smooth light control down to 1%, and dim-to-off functionality provides additional energy savings. Constant lumen maintenance ensures consistent light output over the lifetime of the fixture.

Designed for indoor dry and damp locations, the J-style housing simplifies installation in tight spaces with a 2.0" mounting length. Advanced protections including LED thermal foldback, over-voltage, overload, short-circuit, and over-temperature safeguards provide reliable operation. With high efficiency up to 91%, power factor greater than 0.9, and compliance with UL, FCC Class A, NEMA 410, California Title 24, and RoHS standards, this driver offers dependable performance and a 5-year limited warranty.
