Description

OPTOTRONIC OTi 48W 120-277 2A0 DIM-1 L AUX G2 CC Programmable Linear LED Driver (*2743X6 / 57455)

OPTOTRONIC OTi 48W 120-277 programmable, dimmable family consists of highly efficient, linear, constant current LED drivers. One click programming through the OPTOTRONIC programmer allows OEMs to configure the output current with 1mA resolution. Also, fully customizable by customers are the end-of-life indicator, LED thermal protection, and the constant-lumen maintenance features.

The OPTOTRONIC programmer does not require the driver to be powered up or connected to AC line voltage while programming. The drivers are available with built-in 0-10V dimming protocol with models available in true 1% to 10%. The auxiliary output has the capability to power various sensors.
