The OSRAM DALI Technology is a versatile and reliable lighting solution suitable for a range of applications. This product is designed to be installed in emergency lighting systems according to IEC 61347-2-3, appendix J, making it a reliable choice for buildings and facilities requiring emergency lighting.

One of the key benefits of this product is its flexibility in output, with a versatile DALI window driver up to 90 W. It also boasts high efficiency and reliability, ensuring that it provides consistent and dependable lighting. The system is protected by thermal management and Smart Control, which helps prevent damage and prolong the lifespan of the product.

The OSRAM DALI Technology is suitable for use in luminaires with flexible current settings, such as DALI, CLO, and LEDset, and is suitable for indoor SELV and non-SELV installations. It is also suitable for luminaires of protection class I, making it a great choice for a wide range of settings.

The system’s OSRAM DALI Technology allows for easy use in corridors and restrooms with its three-level Corridor function. The Touch DIM application also makes it easy to control via pushbutton or sensor, while the energy-efficient Touch DIM operation ensures that the product automatically switches off when sufficient residual light is detected. This makes it ideal for use in smart buildings and installations.

The OSRAM DALI Technology is also suitable for emergency installations according to EN 60598-2-22 and IEC 61347-2-13, appendix J, thanks to DC detection (0 Hz, pulsating DC), which is switchable on/off. Additionally, the product provides feedback on power consumption and operating hours, making it a great choice for buildings according to EPBD/BREEAM/LEED due to its automatic Constant Lumen Output setting.

This product features a supply voltage of 220-240 V and line frequency of 0 Hz, 50 Hz, or 60 Hz. Its safety standards are compliant with EN 61347-1, 61347-2-3, 61347-2-13, and 62384, and RI suppression complies with EN 55015:2007+A1:2007/CDN. Line harmonics meet EN 61000-3-2 standards, and the product’s wide temperature range of -25 – +60 °C makes it a suitable choice for installations in various environments.

Finally, the OSRAM DALI Technology comes with a 5-year guarantee, providing peace of mind and confidence in its quality and reliability. The product is exported to various regions, including Europe, the Middle East, and Africa, making it a trusted and dependable lighting solution for a global market.
