Description

The eldoLED OPTOTRONIC OTi 40W 347V Compact is a high-performance, programmable constant current LED driver engineered for 347V input commercial lighting applications. This compact driver delivers precise output ranging from 400–1400mA with 1mA programmable steps and a default of 700mA, ensuring optimal control for a wide range of LED fixtures. Featuring true 1% dimming via a 0–10V interface and advanced thermal foldback, it maintains consistent lumen output while protecting LEDs from overheating. Its optional auxiliary output allows seamless integration with sensors and smart lighting systems, making it ideal for modern commercial and industrial projects.

Designed for lighting designers, facility managers, and electrical contractors, the OTi 40W 347V Compact combines high efficiency with robust protection. Overvoltage, overload, and short-circuit safeguards ensure reliable operation, while its compact F-style and J-style housings, IP20 rating, and UL Class P, FCC Part 15, and RoHS compliance simplify installation and code compliance. Whether used for new construction or retrofits, this driver delivers programmable performance, energy efficiency, and enhanced dimming control for professional-grade lighting solutions.

Key Features & Benefits
