Osram Power Supply Optotronic OTi DALI 80/220-240/1A6 LT2 L

LEDVANCE OPTOTRONIC DALI SELV LEDset LT2 80W is a professional constant current LED driver designed to power LED modules in indoor lighting applications. Fully compatible with the DALI-2 protocol, it provides smooth dimming from 1% to 100% and is ideal for intelligent lighting systems in offices, retail spaces, schools, hospitality environments and commercial buildings. Thanks to LEDset2 technology, the output current can be programmed to match the connected LED module, offering maximum flexibility for lighting designers and installers.

LEDVANCE OPTOTRONIC DALI SELV LEDset LT2 80W

This professional LED driver has been developed to deliver outstanding performance, long service life and maximum reliability. The output current is programmable from 600 to 1,550 mA, while the output voltage automatically adjusts between 20 and 54 V DC (SELV) according to the connected load. With a maximum output power of 80 W, a 220-240 V AC input voltage and efficiency above 90%, it provides reliable operation while reducing energy consumption.

The driver incorporates several advanced features for professional lighting installations, including Constant Lumen Output (CLO) to maintain consistent light output throughout the installation's lifetime, Driver Guard intelligent thermal protection, operating hour monitoring and full compatibility with DALI-2 lighting management systems. Integrated overload, short-circuit, overtemperature and Hot Plug protection ensure safe and reliable operation even in demanding applications.

With a service life of up to 100,000 hours, extremely low standby power consumption and output ripple below 1%, the OPTOTRONIC LT2 series is an excellent solution for architectural lighting, retail environments, offices, schools and any professional installation requiring high energy efficiency, intelligent lighting control and long-term reliability.
