KNX DIMMING ACTUATOR 4 GANG 250W

The universal dimming actuator works according to the leading edge phase control or trailing edge phase control dimming principle and makes switching and dimming of HV incandescent lamps, HV halogen lamps and LV halogen lamps with inductive transformers or Tronic- Transformers possible by means of conventional transformers and Tronic-Transformers. It is also possible to activate dimmable HV-LEDs or compact fluorescent lamps. LV-LEDs can also be activated via electronic or conventional transformers. The characteristic of the connected load - provided that the load is supported - can be automatically measured separately for each output channel and the appropriate dimming procedure can be set. Alternatively, it is possible to predefine the dimming procedure using the ETS configuration. This procedure is necessary for loads that do not enable automatic calibration (e.g. with compact fluorescent lamps). There are up to 4 dimming channels available depending on the device variants. To simplify the configuration, all existing dimming channels can be assigned to the same parameters in the ETS and thus configured identically. The number of parameters is thereby reduced in the ETS and applied automatically on all channels. To increase the channel power, the device variant "4-gang" can be wired in parallel by reducing the number of channel outputs (not with HV/LV-LED lamps or compact fluorescent lamps). The assignment of parallel to wired dimming outputs to the KNX-controllable dimming channels takes place in the ETS. The device permits the separate feedback of the individual switching and brightness statuses of the connected loads to the KNX. Moreover, a short-circuit and load failure can be signalled separately to the KNX for each dimming channel. The operating elements (4 pushbuttons) on the front panel of the device allow the dimming channels to be switched on or dimmed by manual operation in parallel with the KNX even without bus voltage or in a non-programmed state. This feature permits fast checking of connected loads for proper functioning.
