Information about Family

Now you can have high quality, reliable and versatile lighting wherever you need it. A super slim (11 mm height) profile and flicker-free light make this LED driver ideal for modern, creative and innovative designs. Fast and easy to program in floor-standing, pendant and surface-mounted luminaires and panels, when used as a system solution with other elements from the Ultraflat range it lets you bring your most creative lighting designs to fruition — quickly, easily and without fuss. What is more, you can now create precisely the lighting solution your project needs without having to find a compromise between design and efficiency. The intelligent features of this driver, which include fit for SMART GRID, fit for emergency, corridor and Touch DIM capabilities, make it versatile and easy to manage, while its compatibility with several programming interfaces (DALI lighting, LEDset2, NFC) ensure flexibility. In short, the OPTOTRONIC Intelligent UltraFlat Dimmable DALI may be half the height of a standard OTi DALI, but its optimized performance and functionality, and ease of integration with other elements from the Ultraflat range, means that it can provide just about any feature that modern lighting manufacturers, designers and planners can think of.
Areas of application
  • Linear lighting for office, education, industry, storage areas and retail
  • Installation in emergency lighting systems according to IEC 61347-2-13, appendix J
  • Suitable for luminaires of protection class I
