OT 20W UNV 0A5 DUALDIM DIM-1 J-HOUSING J25
Description
Description
The eldoLED OPTOTRONIC OT20W Dual Dim-1 LED Driver is a compact, programmable constant current solution designed for architectural and commercial LED applications. This 20W driver delivers an adjustable output current of 250–500mA in 1mA steps, supporting both 0–10V analog and forward/reverse phase-cut dimming for smooth, flicker-free light control. Its 26–42VDC output voltage range and flexible F-style or J-style housing allow for installation in tight spaces without compromising performance. Dim-to-off functionality at 0.6V (off) / 1V (on) ensures energy efficiency and precise light management.
Engineered for reliability and safety, the OT20W includes NTC thermal foldback protection at 95°C, compliance with UL Class P, FCC Class A & B, RoHS standards, and IP20 dry/damp location rating. With a rated lifetime of 50,000 hours at 80°C Tc and a 5-year warranty, this driver provides long-lasting, energy-efficient performance, making it ideal for commercial and architectural lighting projects where space is limited.
