After receiving market positive response toward LDH-45 series, MEAN WELL is delighted to unveil LDH-45-DA/WDA series to response to the increasing demands of DALI intelligent control applications. LDH-45-DA/WDA series remains the same housing design and electric features of LDH-45, but adding DALI Dimming function. Furthermore, there are pin style and wire style models with multiple voltage choices (9~18VDC/18~32VDC) for selections. Besides, LDH-45-DA/WDA series is equipped with PWM & analog dimming functions. The output current can be remotely ON/OFF controlled and adjusted by external PWM signal or 0.25~8VDC voltage, which is able to fully satisfy the needs of LED lighting fixtures requiring DC input DALI intelligent control application.
