Description

OPTOTRONIC OT 50W UNV 1A4 CS DIM L CC Current Select Linear LED Driver (*2743WP / 57440)

OPTOTRONIC OT 50W UNV 1A4 CS DIM L Constant Current LED Driver is part of OSRAM’s high-efficiency, linear dimmable driver family designed to deliver superior performance and flexibility in a wide range of lighting applications. Engineered for precision and reliability, this constant current driver features an integrated current selection (CS) mechanism that simplifies configuration and streamlines installation. With a universal input voltage range and true 10% dimming via standard 0–10V protocol, it ensures smooth and consistent light output.

Key advanced features include optional LED thermal protection, constant lumen maintenance, and an end-of-life indicator—all of which can be tailored to meet your specific application needs. Additionally, its auxiliary output can supply power to external sensors and controls, making it ideal for connected lighting systems.

The OT 50W UNV is a smart solution for commercial, architectural, and OEM lighting designs.
