Key Features

• Four Dimming Channels: Controls up to 300W per channel, with parallel operation options of 2 channels (500W), 3 channels (750W), or 4 channels (1000W) for high-load lighting systems.

• Wide Voltage Compatibility: Operates within 110–230V AC, 50–60Hz, suitable for both residential and commercial electrical networks.

• Comprehensive KNX Control: Includes switching, relative and absolute dimming, status feedback, scene control (up to 16 scenes), staircase lighting, flashing, delay, threshold, forced, and safety functions.

• Customisable Dimming Curves: Offers six preset dimming curves plus one user-defined option, configurable through ETS for precise lighting adjustments.

• Advanced Features: Incorporates manual operation, output indication, central control, and an operating hours counter for system monitoring and maintenance.

• Efficient DIN-Rail Installation: Compact 8SU MDRC housing, powered via the KNX bus (7.5 mA), ensuring secure, easy, and reliable setup.

Product Description

The GVS KNX Universal Dimming Actuator with Secure, 4-Fold, 8SU MDRC is a powerful and flexible dimming solution designed for comprehensive lighting control in KNX automation systems. Supporting up to 300W per channel, it allows parallel operation of multiple channels—2 for 500W, 3 for 750W, or all 4 for a combined load of 1000W—offering scalability for diverse lighting applications.

With leading and trailing edge phase dimming, it ensures smooth, flicker-free performance for LED, incandescent, and halogen lighting. Operating across 110–230V AC, 50–60Hz, the actuator provides global installation compatibility.

It integrates complete KNX functionality, including switching, dimming (relative and absolute), status feedback, scene recall (up to 16 scenes), staircase lighting, flashing, delay, threshold, forced, and safety functions, delivering advanced lighting control for any environment.

Additional features include manual operation, output indication, central control capability, and an operating hours counter, allowing easy maintenance and system diagnostics. Through ETS configuration, users can fine-tune lighting behaviour using six preset dimming curves plus one custom option.

Mounted in a compact 8SU DIN-rail housing and powered solely via the KNX bus (7.5 mA), the GVS KNX Universal Dimming Actuator with Secure – 4-Fold ensures efficient, secure, and intelligent lighting management for modern smart building projects.
