## Summary description

Flush-mounted dimming actuator JUNG FM UD 20250 UP for AC mains (230 V) with maximum switching capacity 250 W. Operates on 868 MHz radio frequency and fits compact installations (53 × 28 mm). Designed to control lighting loads, enable smooth dimming and integrate with home automation systems supporting radio actuators.

## Long description

Flush-mounted dimming actuator JUNG FM UD 20250 UP is a compact radio-capable module for control of lighting circuits on AC mains (230 V) with a maximum load of 250 W. The unit accepts dimmable incandescent, halogen and compatible LED and CFL loads and communicates on the 868 MHz radio band. Its slim housing (53 × 28 mm) is designed for installation in standard appliance boxes or surface-mounted housings, enabling integration into eNet-based home automation systems and local manual control via a prog button and LED status indication.
Advantages
The device supports soft-start switch-on to extend lamp life, stores switch-on and minimum brightness settings, and offers scene operation and status feedback to radio transmitters. Integrated electronic short-circuit and over-temperature protection ensure safe operation; the actuator can be configured for the specific dimming principle required by the connected load. When connected to an eNet server, it provides encrypted radio transmission (AES-CCM), remote software updates, repeater capability and extended configuration options for brightness, speed and timing.
Suitable for
Switching and dimming of incandescent and halogen lamps
Control of electronic transformers for halogen or LED lamps
Dimmable inductive transformers and compatible HV-LED or compact fluorescent lamps
Integration in eNet radio home automation installations
Key specifications
Supply voltage: 230 V AC
Maximum switching capacity: 250 W
Radio frequency: 868 MHz with AES-CCM encryption support via eNet Server
Dimensions: 53 × 28 mm (flush-mounted module)
Supported lamp types: incandescent, HV halogen, dimmable electronic transformers, dimmable inductive transformers, HV-LED, dimmable CFL
Protection: electronic short-circuit protection (permanent switch-off within 7 s), electronic over-temperature protection
Control options: local Prog button, radio transmitter feedback, eNet server configuration
How to use
Install the actuator in an appliance box according to DIN 49073 or in a compatible surface-mounted or built-in housing. Connect the device to the 230 V supply and the load following applicable electrical regulations. Pair the actuator with suitable eNet radio transmitters or register it to an eNet server for remote configuration. Use the Prog button for basic local commissioning and the LED status indicator to verify operation. Configure dimming parameters, brightness limits and safety functions either locally or via the eNet server as required.
Usage recommendations
For reliable dimming performance, match the actuator settings to the connected lamp type: select the appropriate dimming principle (automatic or manual) when installing and use power boosters if the total load exceeds the module capacity. Use the eNet server to enable AES-CCM encrypted communication, apply software updates and review error logs. Observe wiring and installation standards and ensure loads are within the specified 250 W rating.
