OTI 55W UNV 2A0 1DIM AUX DIM-1 J20
Description
Description
The eldoLED OPTOTRONIC OTi 55W Compact is a programmable constant current LED driver designed for commercial and architectural lighting applications. Offering a wide output range of 700–2000mA with 1mA resolution, it allows precise control over LED fixtures while supporting isolated 0–10V dimming down to 1% with dim-to-off. The driver delivers smooth, flicker-free dimming, constant lumen maintenance, and thermal protection via an NTC sensor, ensuring long-term performance and safety. Optional AUX output enables integration with sensors or other control devices, making it ideal for high-performance luminaires in offices, retail spaces, or architectural installations.
Built for efficiency, reliability, and compact installation, the OTi 55W Compact comes in F-style or J-style housings and supports remote mounting up to 16 feet. It is UL Class P listed, FCC Class A compliant, RoHS certified, and IP20 rated. With protections against over-voltage, overload, short-circuit, and thermal foldback, it meets strict commercial lighting standards while delivering consistent illumination and energy efficiency.
