Information about Family

Future proof – ready for intelligent, efficient and robust industry solutions.

The DEXAL Interface and the DiiA -250 as well as an integrated DiiA -251, -252, -253 for luminaire info and monitoring data present one key characteristic of this LED Driver. Additionally the module is fully digitally programmable by DALI, NFC and LT2 and contains very wide operating windows up to 600mA.
Areas of application
  • Linear and area lighting
  • Industry lighting
  • 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.
