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

Multichannel universal dimming actuator optimized for dimming retrofit LED lamps. It is also suitable for dimming incandescent lamps, low-voltage halogen lights with conventional or electronic transformers, 230 V halogen lamps, and dimmable energy-saving halogen lamps. The device features automatic load detection (which can be deactivated) and a separate N-connection per channel. Parallel connection of the outputs is possible to increase the output power, and outputs can be connected in parallel in any configuration. The minimum load is 2 W. Manual operation on the device is also possible without bus voltage or in an unprogrammed status. Programming of the device can be done without applied 230 V supply voltage. It includes extensive test and diagnosis functions for the i-Bus tool and allows for fast parameter setting in ETS using copyable channel templates. The actuator has an integrated bus coupler.

Nominal 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 in trailing edge control, 4 x 80 W/VA to 1 x 200 W/VA in leading edge 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.
