Light Control Meets Advanced Scheduling

Unlike conventional twilight switches, the SOU-13/1 combines a high-precision light sensor with a fully featured digital time switch. Lighting can be controlled according to measured light intensity while simultaneously following daily, weekly, yearly, or astronomical schedules. This allows users to limit twilight operation to specific periods, ensuring lighting is active only when truly needed.

Connected Through Wi-Fi

The integrated Wi-Fi interface and built-in web server make configuration and monitoring simple from a smartphone, tablet, or computer. Time synchronization via an NTP server ensures accurate operation without manual adjustments, while remote web access allows users to configure and control the device from virtually anywhere.

Flexible Applications

The SOU-13/1 is ideal for controlling:

Street and public lighting
Parking lot illumination
Advertising and billboard lighting
Garden and landscape lighting
Commercial and industrial facilities

Its external IP65-rated sensor can be mounted on a wall or inside a panel, providing reliable light measurement in demanding environments.
