As the DALI Association keeps adding new lighting control functions under the IEC 62386 international regulation to the DALI 2.0 version digital lighting control products, the whole lighting control system can achieve the goals: simple setting, open system, and high compatibility. Compared with DALI 1.0 Version, DALI 2.0 Version adds the definitions and functions of the input device and control device, improving and completing the overall DALI lighting system. In the future, LED driver will become a basic lighting device of DALI 2.0 control system. Digital lighting enables lighting control to set up easily and reduce the cost and working time of rewiring.
For the indoor DALI dimming solution, MEAN WELL improved the product functions and launched products that comply with DALI 2.0 regulations, including LCM-DA2 series and PWM-DA2 series.
C.C mode LCM-25/40/60DA2 series has built-in DIP-SWITCH function, providing multiple current adjustable functions. The adjustable output current can facilitate users to reduce the number of models for different LED modules. LCM-DA2 series can be integrated into a DALI 2.0 digital lighting system application. In addition, the LCM-25/40/60DA2 series also provides Push dimming function. Both traditional wall rocker switch and DALI 2.0 digital lighting are provided.
In addition, C.V mode PWM-60/90/120DA2 series can be applied to 12V/24V and 48V for LED light strips. Both constant current and constant voltage luminaires can be easy to installation at the same project.
MEAN WELL DALI 2.0 LCM and PWM LED driver series not only comply with international safety certification but also has been upgraded to comply with IEC62386-101/102/207 and 251 functions. Moreover, these series also comply with EN61347-2-13 for emergency lighting (EL) applications, allowing users to combine the emergency lighting system to extend the product application range. In addition, MEAN WELL keeps promoting the DC House concept with DC lighting application. These series of products can be used with DC 380V, supporting diverse applications.
