Description
Description
The eldoLED OPTOTRONIC OT20W Dual Dim-1 LED Driver is a compact, high-performance solution for architectural and commercial LED installations requiring advanced dimming and precise control. This 20W constant current driver features dual dimming capability via 0–10V analog and forward/reverse phase-cut inputs, enabling smooth, flicker-free dimming from 0.6V dim-to-off to full brightness. With a programmable output range of 250–500mA in 1mA steps and a wide output voltage range of 26–42VDC, the OT20W ensures flexible and reliable operation for a variety of LED fixtures.
Designed for durability and safety, the OT20W includes NTC thermal foldback protection at 95°C, dim-to-off functionality, and full compliance with UL, FCC, RoHS, and IP20 standards. Its compact F-style and J-style housings allow easy installation in tight spaces, while the driver delivers a long 50,000-hour lifetime at 80°C Tc. Backed by a 5-year warranty, this driver offers reliable, energy-efficient, and programmable LED performance for demanding indoor applications.
