Information about Family

Future proof – ready for wireless applications.

This product is industry ready thanks to a high surge / burst (up to 4kV) and a low standby. For luminaire info and monitoring data the DiiA standards -251, -252, and -253 are integrated and the device is fully digitally programmable by DALI, NFC and LT2. It’s also possible to select AM or AM/PWM dimming.
Areas of application
  • Linear lighting for office, education, industry, storage areas and retail
  • DEXAL, easy connection to different partner BMS systems
  • Suitable for "Works with OSRAM DEXAL" partner components
  • Suitable for luminaires of protection class I
Ecodesign regulation information:
Intended for use with LED modules.
The forward voltage of the LED light source shall be within the defined operating window of the control gear in all operating conditions including dimming if applicable.

Separate control gear and light sources must be disposed of at certified disposal companies in accordance with Directive 2012/19/EU (WEEE) in the EU and with Waste Electrical and Electronic Equipment (WEEE) Regulations 2013 in the UK. For this purpose, collection points for recycling centres and take-back systems (CRSO) are available from retailers or private disposal companies, which accept separate control gear and light sources free of charge. In this way, raw materials are conserved and materials are recycled.
