DALI Alliance introduces Part 151 for outdoor lighting surge protection

The DALI Alliance has developed Part 151, a new specification designed to provide a defined framework for protecting DALI control devices from induced electrical surges in outdoor lighting applications.

This standard establishes minimum requirements for surge protection when control devices are exposed to electrical transients. Such risks are particularly prevalent in outdoor installations where signal cables between luminaires and remote sensors or controllers may be affected by nearby lightning strikes or switching operations on adjacent power lines.

As outdoor lighting systems become increasingly networked, control devices are often located outside the luminaire itself. This requires additional measures to protect connected equipment from induced surges. TE Connectivity’s LUMAWISE Endurance Bridge assembly is among the first products to be certified under this new specification.
