KNX dimming actuator, 4-gang

Two variants, ideal for dimming high-voltage LEDs

The Gira KNX dimming actuator 4-gang is designed for switching and dimming a variety of different lamps. It features a simplified DRA wiring concept with high-quality connection terminals on both sides of the housing, enabling quick and safe installation. In a compact design of only four modular widths, the KNX dimming actuator provides a total of four outputs for the separate control of lighting circuits of up to 225 W each.

The new products are particularly suitable for controlling modern high-voltage LEDs, with up to 200 W dimmable per output. For even more power, Gira System 3000 power boosters are also available.

The KNX dimming actuator 4-gang is available in Standard and Komfort variants. The Standard variant has the most frequently required functions, while the Komfort variant offers additional useful functions.

  • Extensive scene functions can be implemented (16 scenes for Standard variant, 64 for Komfort variant)
  • Easy logics can be implemented even without a server
  • Individually adjustable dimming characteristic per LED dimming channel
  • Power extension via power boosters or, in the Komfort variant, via parallel connection of the outputs
  • Spacious terminal compartment with high-quality screw terminals and relay
  • Suitable for use in both private and commercial environments
  • Easy start-up, updates, and troubleshooting with the Gira ETS Service App

  • KNX Secure is fully supported
  • All software functions can be fully upgraded with any security updates or function extensions
