The DALI Dimmer SR-2304B is a constant voltage dimming controller with 4 channel, 5A per channel output, which complies to standard DALI protocol with 1 DALI address to control 4 channels synchronously. The DALI address can be manually assigned and shown on the numeric digital display or automatically assigned by master controllers. 1-4 DALI addresses can be configurable for 4 channels to work synchronously or separately. 0.1%-100% smooth dimming can be achieved by the DALI dimmer via logarithmic dimming, which is perfect for human's vision. The DALI dimmer can not only be compatible with DALI masters, but also push switch to get dim and switch functions under the situation without DALI signal.
