OTI 50W UNV 1A4 1DIM DIM-1 J10 Optotronic
Description
Description
The eldoLED OPTOTRONIC OTi 50W Programmable Linear LED Driver is engineered for precision, reliability, and high-performance indoor lighting applications. Delivering programmable output current from 400–1400mA with 1mA resolution (default 1050mA), it provides accurate LED control for a variety of fixtures. The driver supports isolated 0–10V analog dimming down to 1% with dim-to-off capability, ensuring smooth, flicker-free operation. Advanced features like constant lumen maintenance, soft start, and an end-of-life indicator protect the LEDs and extend their operational lifetime. Thermal foldback via the NTC input safeguards against overheating, making it ideal for architectural-grade LED installations.
Designed for commercial and architectural environments, the OTi 50W driver combines efficiency, safety, and versatility. UL Class 2 recognized, FCC Class A compliant, and RoHS certified, it meets strict safety and performance standards. With built-in over-voltage, overload, short-circuit, and thermal protections, along with a compact linear form factor and remote mounting capability of up to 16 feet, this driver is perfect for offices, retail spaces, and other indoor LED lighting projects requiring high-quality, programmable performance.
