gira Dimmaktor Mini 20 250VA is a compact DIN-rail dimmer actuator designed for installation in electrical distribution boards. With a rated output of 250 VA, it provides centralized or remote control of lighting intensity as part of smart building or home automation systems. The unit is intended for switching and dimming of compatible loads and can be integrated into automation controls for timed, scene-based, or remote lighting adjustments.
Advantages
The compact form factor allows installation in crowded distribution panels while preserving space for other modules. Its 250 VA output supports a variety of lighting loads compatible with phase-control dimming, enabling flexible use across different applications. Designed for DIN-rail mounting and integration into automation systems, it simplifies wiring and centralizes control of multiple lighting circuits.
Suitable for
- Retrofit or new electrical distribution boards where space is limited
- Residential and small commercial lighting circuits requiring dimming
- Integration with building automation systems for scene and remote control
- Centralized control of groups of lights such as living rooms, corridors, or small offices
When it may not be suitable
This actuator is intended for loads up to 250 VA; it is not suitable for high-power lighting circuits or large groups of luminaires that exceed this rating. It is designed for dimmable and compatible load types; non-dimmable lamps, certain LED drivers or electronic transformers may not behave correctly and can reduce dimming performance or cause flicker.
Key specifications
- Mounting: DIN-rail module for installation in distribution boards
- Rated load capacity: 250 VA
- Function: switching and phase-control dimming of compatible lighting loads
- Control: designed for integration with automation and centralized control systems
- Form factor: compact mini-module suitable for tight panel spaces
How to use
Install the unit on a standard DIN-rail inside the distribution board and connect supply, load, and control wiring according to applicable wiring diagrams and local electrical codes. Configure the device within the building automation or control system to assign channels, scenes, or schedules. Test dimming with the specific lamps and transformers used on the circuit to verify compatibility and smooth operation before commissioning.
What to consider before purchase
- Verify total connected lamp load does not exceed 250 VA per actuator
- Confirm lamp types and drivers are dimmer-compatible to avoid flicker or reduced range
- Ensure available DIN-rail space and panel clearances for installation
- Check compatibility with the intended automation or control protocol
Usage recommendations
For reliable dimming performance, pair the dimmer actuator with lamps and LED drivers that manufacturer documentation lists as compatible with phase-control dimming. When installing multiple actuators, plan load distribution to avoid exceeding individual device ratings and to maintain balanced circuits.
