Leading building automation solution provider LOYTEC electronics today announced that its LDALI-PWR4-U is the world’s first DALI bus power supply, which successfully passed the DALI-2 certification process.

DALI-2 certification is run by the Digital Illumination Interface Alliance (DiiA), an open consortium of lighting companies that promotes the global adoption of digital lighting control systems using DALI technology. Only certified products can carry the DALI-2logo. The DALI-2 certification brings the promise of significantly improved interoperability as well as additional functionality compared with current DALI (version 1) systems in the market.

Probably the most important improvement of DALI-2 is the addition of application controllers, bus power supplies and input devices such as multi-sensors and buttons to the DALI standard. Prior only ballasts and luminaires were covered by the DALI standard leaving the other components typically found in a lighting control system, proprietary devices. Thus, DALI-2 enables planers and system integrators to implement a lighting control system consisting only of products following the DALI standard.

DALI-2 certified devices are listed in the product database available on the DiiA web site. As more DALI-2 certified products become available planers and system integrators will be able to choose from a wide range of products to deliver a complete DALI-2 lighting system.
