System 3000 universal LED dimming insert comfort 2-wayFeatures: Two independent outputs for two groups of lights. Switching and dimming of incandescent lamps, HV halogen lamps, electronic transformers for halogen or LED lamps, dimmable inductive transformers for halogen or LED lamps, HV LED or compact fluorescent lamps. Connection of extensions possible. With the System 3000 3-wire extension insert in conjunction with a System 3000 2-way operating top, both outputs can be operated separately. Automatic or manual setting of the dimming principle that suits the load (leading edge or trailing edge). Display of the set operating mode via LED. Lamp-friendly switch-on. Switch-on brightness can be saved permanently. Switch-on with the last set brightness or saved switch-on brightness. Minimum brightness adjustable. Electronic short-circuit protection. Electronic overtemperature protection. Operation with and without neutral conductor connection. Touch dimmer. Combination with KNX RF operating top unit 1-way 2-way: dimmer actuator channel 1-way. Sensor channel 1-way or 2-way. Local control of the System 3000 insert possible. Radio control of other KNX devices as a sensor possible. Function selection of the insert: adjustable dimming principle, staircase function, scene function, locking function, time delays. Extension input as an additional operating point for the System 3000 insert or for radio control of other KNX devices as a sensor possible. Notes: In principle, the dimmer can be operated without connecting the neutral conductor, but some LED and CFLi lamps require the neutral conductor connection to avoid flickering. When operating without a neutral conductor, the minimum load for incandescent lamps, HV halogen, Tronic transformers and wound transformers increases to 50 W. Electronic transformers and ballasts for LED lamps can be operated using the dimming method specified by the manufacturer. If the ambient temperature is higher than 25 °C, the connected load must be reduced.
