Information
DM 4 T KNX – 4-channel universal dim actuator FIX2
Art. No. 4940275
Application
The Theben DM 4 T KNX is a universal 4-channel dim actuator from the FIX2 series for KNX installations. The device is designed for dimming various types of lighting and is suitable for use in residential, office and commercial buildings. It also supports fan control. The actuator is compatible with different load types (R, L, C) and can be operated manually even without bus voltage.
Functions
- Universal 4-channel KNX dim actuator (FIX2 series)
- Suitable for dimming incandescent lamps, low- and high-voltage halogen lamps, dimmable LEDs and CFLs
- Supports resistive, inductive and capacitive loads (R, L, C)
- Fan control possible
- Manual operation on the device, even without bus voltage
- LED status indication per channel
- Automatic load detection (can be deactivated)
- Dimming capacity per channel: 5–400 W/VA
- Parallel operation possible: up to 800 W/VA on one channel
- Expandable with DMB 1 T KNX dim boosters (each +300 W/VA)
- Maximum dimming capacity with 4 boosters: 2000 W/VA
