Information about Family

The OPTOTRONIC LED constant current driver family has options to suit a range of wattages, with input voltage from 120…277 V and an output current of 700 mA. It protects your light installation from overtemperature and gives high surge protection of up to 6 kV (L-N) / 6 kV (L/N-PE). Suitable for use outside in street lighting, urban applications and industrial lighting, and for use in luminaires of protection class I, this highly efficient and reliable power supply gives you high IP protection (IP65) and a wide operating temperature range.
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.
