Busch-Jaeger LED dimmer 4x210 W/VA UD/S4.210.2.1 Busch-Installationsbus KNX REG-Universa

Multi-channel universal dimmer actuator, optimized for dimming retrofitted LED lamps. It is also suitable for dimming incandescent lamps, low-voltage halogen lamps with conventional or electronic transformers, 230 V halogen lamps, and dimmable energy-saving halogen lamps. The device features automatic load detection (which can be disabled) and a separate N connection per channel. Parallel connection of the outputs is possible to increase output power, and the outputs can be connected in any configuration. The minimum load is 2 W. Manual operation at the device is also possible without bus voltage or in an unprogrammed state. Programming of the device can be done without applying 230 V supply voltage. It includes extensive testing and diagnostic functions for the i-Bus tool and allows for quick parameterization in ETS using copyable channel templates. The actuator has an integrated bus coupler.

Rated power at 230 V mains voltage:

• 230 V incandescent and halogen lamps: 4 x 210 W/VA to 1 x 600 W/VA.
• Dimmable 230 V LED: 4 x 210 W/VA to 1 x 600 W/VA with phase-cut control, 4 x 80 W/VA to 1 x 200 W/VA with phase-angle control.
• Inductive L transformers with LED/low-voltage halogen lamp: 4 x 210 W/VA to 1 x 600 W/VA.
• Electronic C transformers with LED/low-voltage halogen lamp: 4 x 210 W/VA to 1 x 600 W/VA.
• Electronic LC transformers with LED/low-voltage halogen lamp: 4 x 80 W/VA to 1 x 200 W/VA.
