Description
Description
The eldoLED OPTOTRONIC OTi 40W 347V Compact is a high-performance programmable LED driver designed for commercial 347V lighting applications. It provides a constant current output from 400–1400mA (default 700mA) with a wide 8–55VDC output range, supporting true 1% dimming and dim-to-off through an isolated 0–10V interface. The driver features advanced thermal foldback via an NTC input, constant lumen output, and optional AUX power for sensors or smart components. Compact F-style and J-style housings allow flexible installation in offices, retail spaces, and architectural lighting projects.
Built for reliability, efficiency, and long-term operation, the OTi 40W 347V Compact includes protections against over-voltage, overload, short-circuit, and over-temperature conditions. With high efficiency (~88% at full load), low inrush current, FCC Class A compliance, IP20 rating, and a 5-year warranty, it delivers dependable performance for demanding commercial lighting systems.
