Multichannel universal dimmer 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 (deactivatable). Separate N connection per channel. Parallel connection of outputs to increase output power is possible. Outputs can be connected in any parallel configuration. Minimum load: 2 W. Manual operation at the device is also possible without bus voltage or in an unprogrammed state. Programming of the device is possible even without an applied 230 V supply voltage. Extensive testing and diagnostic functions via the i-bus tool. Quick 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: 6 x 210 W/VA up to 1 x 800 W/VA. Dimmable 230 V LEDi: 6 x 210 W/VA up to 1 x 800 W/VA in phase-cut, 6 x 80 W/VA up to 1 x 240 W/VA in phase-on. Inductive L transformers with LED/low-voltage halogen lamp: 6 x 210 W/VA up to 1 x 800 W/VA. Electronic C transformers with LED/low-voltage halogen lamp: 6 x 210 W/VA up to 1 x 800 W/VA. Electronic LC transformers with LED/low-voltage halogen lamp: 6 x 80 W/VA up to 1 x 240 W/VA.
