Description

OPTOTRONIC OTi 50W 120-277 1A4 2CH TW L CC Tunable White Programmable Linear LED Driver (*2743Y6 / 58287)

OPTOTRONIC OTi 50W 120-277 indoor linear programmable LED drivers are exclusive to North America. All of these highly efficient constant current drivers dim to 1% with unique architectural grade features—such as Dim to Off, Vaux Output and Synchronized ON/OFF Timing—to meet the tough demands of your lighting projects.

Our 50W indoor linear LED drivers’ programmable output current range (400-1400mA)—coupled with their universal input voltage range (120-277V)—provides you with a highly efficient and flexible drive solution for indoor lighting.

Perfect for indirect and direct lighting, linear and recessed lighting applications.
