Information about Family

Best fit for reliable AstroDIM applications

An easy and fast wireless luminaire programming is made possible via NFC. The AstroDIM operation for which this driver is optimized allows autonomous dimming with five independent levels (astro, time mode). The surge protection goes up to 10 kV which correspond to protection class I or II.
Product family features
  • Supply voltage: 220…240 V
  • Current output range: 70…1,050 mA
  • AstroDIM for autonomous dimming with five independent levels (astro, time mode)
  • Standby power consumption: < 0.5 W
  • Constant Lumen Output (CLO)
  • Integrated customizable thermal management (Driver Guard)
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.
