OTI 50W UNV 1A4 1DIM AUX DIM-1 J10 Optotronic
Description
Description
The eldoLED OPTOTRONIC OTi 50W Compact is a programmable linear LED driver engineered for high-performance indoor architectural lighting applications. Delivering a programmable output current from 400–1400mA with 1mA resolution (default 1050mA), it provides precise control over LED fixtures. The driver features isolated 0–10V analog dimming with dim-to-off, ensuring smooth, flicker-free operation. Advanced features such as constant lumen maintenance, soft start, end-of-life indication, and thermal foldback via NTC input protect LEDs and maintain consistent light output over the lifetime of the installation.
Ideal for designers, contractors, and facility managers, the OTi 50W driver combines high efficiency, safety, and reliability. It is UL Class 2 recognized, FCC Class A compliant, and RoHS certified, making it suitable for code-compliant indoor installations. Built-in protection against over-voltage, overload, short-circuit, and thermal faults ensures dependable operation. Compact dimensions, remote mounting capability, and architectural-grade dimming protection make this driver perfect for commercial projects, office spaces, and modern lighting systems requiring precise, programmable LED control.
