Product remark

The default dimming mode is DEXAL - linear dimming. For DALI Luminaires the DEXAL mode needs to be switched to DALI mode by the programming software./By default the NTC port is enabled with following values: start derating: 6.3 kOhm, end derating 5.0 kOhm, derating level 50 %./The lowest output current is 6 mA and the minimum percentage of dimming is dependent on the programmed nominal output current of the driver./The metal housing must be grounded via the fixation holes. Disconnect power before service./DEXAL Port has basic insulation to mains./1400 mA type: Default output current is 1050 mA

Information about Family

Future proof – ready for wireless applications

The product highlights are an integrated DALI (Version-1) Bus power supply for sensors and wireless radios and an analytics possibility that uses luminaire data like power, energy and operating hours. Fast programming without mains voltage and wide operating windows mark some other benefits.
Product family features
  • Line frequency: 0 Hz | 50 Hz | 60 Hz
  • Supply voltage: 220…240 V
  • Constant Lumen Output (CLO)
  • Monitoring of luminaire operating parameters
  • SELV driver
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.
