## Summary description

DIN-rail dimming actuator SATEL KNX-DIM21 designed for KNX smart home installations. Operates at 230 V, 50/60 Hz with maximum switching capacity 300 W and IP20 protection. Compact module (92×60×70 mm) provides load dimming control for lighting circuits and is suitable for integration into distributed electrical cabinets and automation systems.

## Long description

The SATEL KNX-DIM21 DIN-rail dimming actuator is a compact module for KNX smart home and building automation systems, designed to control lighting circuits at 230 V AC. The device supports two independent channels with stepless dimming control up to 300 W per channel and is compatible with resistive, inductive and capacitive loads. Housed in a module sized 92×60×70 mm with IP20 protection, the unit is suitable for mounting in distribution cabinets and integrates with KNX bus commands to switch lights, adjust brightness levels and recall scenes or other automation functions.
Advantages
The KNX-DIM21 provides precise stepless dimming and two-channel operation within a compact DIN-rail form factor, reducing space requirements in electrical cabinets. Compatibility with R, L and C loads ensures flexible use with a wide range of luminaires, including traditional and electronic lamp types. Integration with the KNX bus allows for centralized and decentralized control, scene recall and remote operation without the need for additional converters, while IP20 protection offers basic mechanical and ingress safety for indoor installations.
Suitable for
 Residential and apartment lighting control in KNX installations
 Commercial or office lighting requiring scene control and dimming
 Distributed installation in electrical cabinets and automation panels
 Controlling resistive, inductive or capacitive lighting loads
Key specifications
 Supply voltage: 230 V AC, 50/60 Hz
 Two independent dimming channels
 Maximum load per channel: 300 W
 Stepless dimming control (continuous brightness adjustment)
 Compatible load types: resistive (R), inductive (L), capacitive (C)
 Protection rating: IP20 (indoor use)
 Mounting: DIN-rail housing
 Module dimensions: 92 × 60 × 70 mm
How to use
The actuator is mounted on a standard DIN-rail inside the distribution cabinet and connected to the 230 V AC supply and to the lighting circuits for each channel. Integrate the device into the KNX bus and assign group addresses and parameters with ETS (or other compatible KNX programming tool) to configure on/off switching, dimming range, scene recall and other functions. After addressing, control is available from KNX panels, switches, sensors or automation logic to dim, switch and recall preset scenes for each channel.
Usage recommendations
For reliable operation, verify load types and combined power per channel do not exceed 300 W. Use in indoor environments only and ensure correct wiring by a qualified electrician. When connecting mixed lamp types on a single channel, test dimming behavior before final commissioning and, if necessary, separate problematic loads to ensure stable performance.
