Description

OPTOTRONIC OTi 85W 120-277 2A3 DIM-1 L HB AUX CC Programmable Linear LED Driver (*274A1S / 57425)

OPTOTRONIC OTi 85W 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 endof-life indicator, LED thermal protection, and the constantlumen 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.

Features:

• OEM Programmable with 1mA resolution to perfectly match LED load and maximize performance
• Integrated OEM programmable features include: Constant lumen maintenance, End-of-life indication, LED thermal protection, Dim to off, Soft start
• Programming doesn’t require powering up or connecting the driver to AC line voltage
• Specification grade dimming down to true 1% or 10% on 0-10V dimmers.
• Slim form factors
