KNX Universal Dimmer Actuator | 4-channel, KNX Secure (10-300-1000W)

GVS KNX Universal Dimmer Actuator | 4-channel, KNX Secure

The GVS KNX Universal Dimmer Actuator, 4-channel, is designed for advanced dimming capabilities across various lamp types, including incandescent, halogen, LEDs, and energy-saving lamps. This device supports both leading and trailing edge dimming and uses KNX Data Secure for reliable, secure operation. Each channel supports a maximum output of 300W, with a total capacity of 1000W in parallel use, making it ideal for modern lighting systems in residential and commercial settings.

Main Features

• Switching and dimming (relative/absolute) for a wide range of lamp types
• Status feedback for switching, brightness, and error notifications (e.g., short-circuit, over-voltage, over-temperature)
• Reset behavior after download, bus failure, or bus recovery
• 6 dimming curves: linear, exponential, cubic, quadratic, logarithmic, root, and user-defined
• Leading and trailing edge phase cut dimming for optimal performance
• Manual operation and output indication
• KNX Data Secure for enhanced protection against unauthorized access
• Support for central control (only for 2- and 4-channel models)
• Individual or parallel output options for higher loads (only for 2- and 4-channel models)
• Additional functions: staircase lighting, flashing switch, delay, scene control, thresholds, forced operation, and operating hours counter
• Logical functions: AND, OR, XOR, gate forwarding, threshold comparator, format conversion, gate function, delay, and staircase lighting
