The Gira dimming actuator 4f REG Std KNX 201500 Secure is a versatile device that has been specially developed for integration into KNX systems. With the ability to switch and dim up to four outputs independently, this dimming actuator offers a flexible solution for controlling various light sources. It supports a wide range of lamp types, including incandescent lamps, HV halogen lamps, dimmable HV LED lamps and compact fluorescent lamps. The integrated bus coupling enables simple connection to the KNX system, while the manual and automatic selection of the dimming principle enables adaptation to the respective load. The dimming actuator is also open-circuit, short-circuit and overtemperature-proof, which increases reliability and safety during operation. Configuration can be carried out via the ETS software, ensuring simple and efficient parameterisation of all dimming channels. With the ability to send feedback and customise the dimmable range, this dimming actuator is an excellent choice for modern smart home applications. Integrated bus coupling for simple KNX integration. Supports a wide range of lamp types, including dimmable LEDs and halogen lamps. Open-circuit, short-circuit and overtemperature protected for increased safety. Simple configuration via ETS software with identical parameterisation. Individual adjustment of the dimming characteristic per channel possible.
