Information about Family

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).
Areas of application
  • Linear lighting for office, education, storage areas and retail
  • Installation in emergency lighting systems according to IEC 61347-2-13, appendix J
  • Suitable for luminaires of protection class I
