Description
Description
The eldoLED OPTOTRONIC OTi 40W 347V Compact is a high-performance programmable LED driver designed for 347V commercial lighting systems. Delivering a constant current output from 400–1400mA (default 700mA), it supports precise LED control with a wide 8–55VDC output range. The driver features isolated 0–10V dimming down to 1% with dim-to-off, advanced thermal foldback via NTC input, and constant lumen output to maintain consistent illumination. Optional AUX output models provide 12V, 20V, or 24V power for sensors or smart devices. Compact F-style and J-style housings enable flexible installation in offices, retail, and architectural lighting applications.
Engineered for reliability, safety, and efficiency, 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 long-lasting, energy-efficient performance for demanding commercial LED lighting systems.
