The dimmer with LED constant current drive can drive LED directly, has four channels, each channel is independent and with two independent output. The output current of each channel can be set by linked switch current button and channel switch current button and can output 350mA/700mA or 700mA/1A. ——needs attention when the output current exceeds the rated current of the load, the load probably will burn out, for example, cannot use a 700mA output to drive 350mA LED. Meantime, in the case of full load, if all LEDs are 350mA, the dimmer can output 8 folds, but if some LEDs are 700mA or 1A, it cannot output 8 folds in some configuration, or the LED cannot reach expectant brightness value. The details are in section 3.3 of the manual. When the output current is set manually, its value can be known via relevant indicators, the details in section 3.3 of the manual. The output can connect with some small power dimmable LED lights. These LEDs can be switched, dimmed, recall scene or other operations via the bus. The devices adopt screw terminals to achieve electrical connection; the connection to the EIB/KNX bus is established via a bus connecting terminal. The input need connect a 12V~48V DC operation voltage.
