Universal Actuator for KNX (AKU Series, 16 A)

The MDT Universal Actuator from the AKU series offers versatile capabilities for switching, shutter control, and heating. The device supports automatic shading, PWM control, and ventilation functions, and can manage up to 8 scenes per channel. Ideal for various KNX applications. Available in versions from 4- to 24-fold with a capacitive load of 100 µF.

Main Features:

• Part of the AKU series, suitable for 16 A with 100 µF capacity
• Automatic shading and louvre adjustment based on sun position
• Heating control with PWM (0-100%) for precise temperature regulation
• Ventilation function for open or tilted windows, with automatic shut-off
• Time functions: switch-on/off delay, staircase lighting function, and direction change delay
• Manual operation via push buttons and LED status indicators for each channel
• Logical linking of binary data and 8 scenes per channel
• Central switching functions and blocking for forced operation
• Adjustable behavior in case of bus voltage failure or recovery
• 8-bit positioning for shutters and blinds, and 1-bit automatic functions
• Separable power supply phases for flexible installation
• Quick application download with ETS 5 or higher, supports long frames
• Output lifespan: 1,000,000 switching cycles (mechanical)
