OPTOTRONIC Intelligent
OTi DALI 50/220-240/1A4 LT2 L
OPTOTRONIC Intelligent � Dimmable DALI


This constant current LED driver is suitable for emergency lighting systems according to IEC 61347-2-13, appendix J, and for use in luminaires of protection classes I and II.
Use it with luminaires of flexible current setting (DALI, CLO, LEDset) and for downlights, spotlights and LED panels � some versions can be installed and/or independently mounted using the matching cable clamp kit.
OSRAM�s use of DALI technology makes this power supply great in various settings; the 3-level corridor function makes it useful for corridors and restrooms, and its easy-to-control TouchDIM functionality is also energy efficient, with automatic switch-off in sufficient residual light.
This versatile DALI driver gives you flexible output characteristics, system protection via thermal management and Smart Control, and quality dimming between 1 and 100 % thanks to amplitude dimming (OTi DALI 15).

Product features

Line frequency 0 Hz - 50 Hz - 60 Hz
Versatile DALI window driver up to 90 W due to flexible output characteristic
