![CDATA[Dimming actuator 1-way for KNX 20 - 500 W VA REG plus Features: Dimming actuator with integrated bus connection. Switching and dimming of incandescent lamps, HV halogen lamps, dimmable HV LED lamps, dimmable compact fluorescent lamps, dimmable inductive transformers with LV halogen or LV LED lamps, dimmable electronic transformers with LV halogen or LV LED lamps. Automatic or manual selection of the dimming principle that suits the load. Idle, short-circuit and overtemperature proof. Manual operation of the outputs independent of the bus (construction site operation also possible). The 1-way dimming actuator can also be used as a speed controller to control the speed of single-phase electric motors. Construction site operation: Outputs can be operated manually without bus voltage, only with the operating voltage. Functions: Independent control of the dimming channels. In construction site operation, the outputs can be operated manually, without bus voltage, only with the operating voltage. Central switching function for controlling all dimming channels.]]>
