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

Additional advantages:

• Weekly programming: The Acti9 IC SMART allows for detailed programming with up to 84 switchings per week, providing great flexibility for managing the on and off times of electrical loads.
• Automatic switch between daylight saving time and standard time: The switch automatically adjusts the schedule according to seasonal changes, eliminating the need for manual adjustments and ensuring that equipment operates efficiently throughout the year.
• Vacation mode: This switch features a lock and vacation schedule function, allowing regular switchings to be disabled during periods of absence and ensuring that electrical loads are not unnecessarily active.

Control and operation:

This model features a backlit LCD display that facilitates the visualization and configuration of programming, as well as providing detailed information about the system status, such as the time, daily switching behavior, and operating time counter. It has 4 control buttons that allow for manual adjustments of settings and remote or manual replacements if necessary.

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

Installation and compatibility:

The Acti9 IC SMART astronomical switch is easily mounted on a DIN rail TH35 according to EN 60715 standards, making it a simple and quick option to install in electrical panels. Additionally, its screw terminals allow for 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.
