ABB UD/S4.315.2.1

Multi-channel universal dimming actuator optimized for dimming retrofit LED lamps. Also suitable for dimming incandescent lamps, low-voltage halogen lamps with conventional or electronic transformers, 230 V halogen lamps, and dimmable halogen. Automatic load detection can be deactivated. Separate N-connection per channel. Parallel connection of outputs is possible to increase output power. Outputs can be connected in parallel in groups. Minimum load: 2W. Manual operation on the unit is also possible without bus voltage or in an unprogrammed state. Programming of the unit is also possible without 230V supply voltage applied. Extensive test and diagnostic functions via the i-bus tool. Fast parameterization in the ETS through copyable channel templates. With integrated bus coupler. Rated power at 230 V mains voltage: 230 V incandescent and halogen lamps: 4 x 315 W/VA to 2 x 500 W/VA in phase control, 4 x 120 W/VA to 2 x 200 W/VA in phase control. Dimmable 230 V LED: 4 x 315 W/VA to 2 x 500 W/VA in phase control, 4 x 120 W/VA to 2 x 200 W/VA in phase control. Inductive transformers with LED/low-voltage halogen lamp: 4 x 315 W/VA to 2 x 500 W/VA. Electronic transformers with LED/low-voltage halogen lamp: 4 x 315 W/VA to 2 x 500 W/VA. Electronic transformers with LED/low-voltage halogen lamp: 4 x 120 W/VA to 2 x 200 W/VA.
