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