Information about Family

0-10V controllable LED driver family incl. AstroDIM functionality

The AstroDIM for autonomous dimming offers five independent levels (astro, time mode) and an isolated 0…10 V interface supports unidirectional telemanagement systems. Another benefit of this driver is the fast programming without mains voltage as well as an IP ration of IP64.
Areas of application
  • Street and urban lighting
  • Industry
  • Suitable for luminaires of protection classes I and II
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.
