System 3000 universal LED dimmer insert comfort - 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. - Automatic or manual setting of the dimming principle suitable for the load (leading edge or trailing edge). - Display of the set operating mode via LED. - Lamp-friendly switching on. - Switch-on brightness can be saved permanently. - Switching on with the last set brightness or saved switch-on brightness. - Hotel card function can be activated: light switches 'on' after a power interruption (from index 02). - Minimum brightness adjustable. - Electronic short-circuit protection. - Electronic overtemperature protection. - Operation with and without neutral conductor connection. - Touch dimmer. Combination with RF operating attachment 1-way / 2-way for KNX: - Dimming actuator channel 1-way. - 1-way or 2-way sensor channel. - Local control of the System 3000 insert possible. - Radio control of other devices for KNX as a sensor possible. - {b}Function selection of the insert:{\b} Dimming behavior and dimming characteristic curve adjustable, soft-on and soft-off function, fading function, staircase function with switch-off warning, scene function (16 scenes), locking function, time delays. Extension input as an additional control point for the System 3000 insert or for radio control of other KNX devices as a sensor possible. 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.
