## Long description

Eti-Polam SOU-1 DIN mount twilight switch is an automatic lighting controller designed for DIN-rail installation in distribution boards. Powered from a 230 V supply and rated for switching currents up to 16 A, the device measures ambient illumination in the 1–50,000 lux range and operates lighting circuits based on night/day thresholds. The compact module is suitable for integration into electrical panels to provide reliable automatic control of outdoor and communal lighting systems.
Advantages
The SOU-1 twilight switch offers a wide sensitivity range from 1 to 50,000 lx, enabling accurate detection of dusk and dawn conditions. Its DIN-rail form factor allows easy mounting in standard consumer units and control cabinets, while the 16 A switching capacity supports typical lighting loads without additional contactors for many applications. The device’s simple functioning and fixed measurement range make it straightforward to install and commission for automatic illumination control.
Suitable for
Street lighting and roadway luminaires

Key specifications
Supply voltage: 230 V AC
Switching capacity: 16 A
Ambient light sensing range: 1–50,000 lux
DIN-rail (EN) mounting format for distribution boards
Designed for automatic day/night switching of lighting circuits
How to use
Install the twilight switch on a standard DIN-rail inside the electrical panel and connect the supply and load conductors according to the wiring diagram provided by the manufacturer. Position the sensor or sensor input so that it receives representative ambient light levels for the controlled area and avoid direct exposure to localized lamps that could affect measurement. Power the unit and verify switching operation by observing behavior at dusk and dawn or by simulating reduced light conditions during setup.
Usage recommendations
For reliable operation, mount the sensor where it measures typical ambient light rather than direct artificial sources, ensure connections meet local wiring standards, and verify that the connected lighting load does not exceed the 16 A switching limit. If loads are inductive or exceed the device rating, use an appropriate contactor or relay.
