The Triac dimmers take the leading edge cut phase dimming mode, which have 2-channels and 4-channels,
each output of them is independent. And due to max. power of each channel is 300W, so It can connect with some
low-power dimming lamps, such as incandescent lamps, HV halogen lamps, LV halogen lamps (with conventional
or suitable electronic transformers), dimming energy saving lamps and LED. These lamps can be switched,
dimmed, recall scene or other operations via the bus.
The device has an integrated short-circuit and over temperature protection. The output power will reduce
when the temperature is over.
The devices adopt screw terminals to achieve electrical connection; the connection to the KNX bus is
established via a bus connecting terminal. The input need connect a 230V AC operation voltage. The following
list provides a functional overview:
◆ Switching the light
◆ Relative dimming
◆ Absolute dimming
◆ Switch and brightness status report, error report
◆ Setting 15 scenes
◆ Staircase lighting function
◆ Bus recovery (or reset) function
◆ Preset value and modify preset value functions
◆ Switch/adjust dimming curve via manual buttons
◆ Output display
The above function of parameters to configure and use are described in the chapter 5. and the Switch/adjust
dimming curve via manual buttons are described in the section 2.7. The database files (.vd4) of the Triac dimmers
are the same with KA/D 0403.1and KA/D 0203.1. But the error report function is different, the detail in section
5.2. Meanwhile, there is added switch and adjust dimming curve via manual button
