The astronomical switch automatically calculates sunrise and sunset times based on the geographical location, eliminating the need for external light sensors. This makes it a very precise and easy-to-configure solution for automatically turning lights or other electrical loads on and off, saving energy and reducing equipment wear.

Additional Advantages:

• Weekly Programming: The Acti9 IC SMART allows detailed programming with up to 84 switchings per week, providing great flexibility to manage the on/off times of electrical loads.
• Automatic Summer and Winter Time Change: The switch automatically adjusts the time according to seasonal changes, eliminating the need for manual adjustments and ensuring equipment operates efficiently throughout the year.
• Holiday Function: This switch features a lock and holiday schedule function, allowing regular switchings to be deactivated during absence periods, ensuring that electrical loads are not unnecessarily active.

Control and Operation:

This model features a backlit LCD display that facilitates viewing and configuring programming, as well as providing detailed information on system status, such as the time, daily switching behaviour, and runtime counter. It has 4 control buttons that allow manual adjustments to configurations and enable remote or manual replacements if necessary.

The switch also allows compensation adjustments to modify sunrise and sunset times based on specific installation needs, offering additional flexibility in operation.

Installation and Compatibility:

The Acti9 IC SMART astronomical switch is easily mounted on a DIN rail TH35 in accordance with EN 60715 standard, making it a simple and quick option to install in electrical panels. Additionally, its screw terminals provide a secure connection for solid or flexible cables up to 2.5 mm².

This switch is compatible with a wide variety of electrical loads, from incandescent and halogen lamps to low-power LED lamps, making it ideal for managing different types of lighting in an installation.
