Information about Family

De-risk your business - easy, wide range of usage, flexible

Some benefits of this product are its efficiency which goes up to 90%, its long lifetime and guarantee. It is also flexible in its current setting thanks to 4 DIPSwitches and due to a low ripple the lighting quality is improved. This device is also suitable for emergency lighting units.
Product family features
  • Line frequency: 0 Hz | 50 Hz | 60 Hz
  • Versatile scope of application due to output power range of up to 75 W
  • Supply voltage: 220…240 V
  • Available with output current range: up to 1,400 mA
  • SELV system
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.
