Suitable for

• Outdoor street and pathway lighting
• Garden and landscape illumination
• Building facade and architectural lighting
• Parking lot and driveway lighting
• Commercial signage and display illumination

When it may not be suitable

This device is not intended for indoor applications where constant lighting is required regardless of ambient light levels. It may also be unsuitable for environments with rapidly fluctuating light sources, such as areas with frequent artificial light interference, which could cause the switch to cycle on and off unnecessarily.

Key specifications

• Rated current: 16A
• Operating voltage: 230V AC
• Light sensitivity range: Adjustable
• Mounting type: DIN rail
• Protection class: IP20

How to use

The ETI ETS-16B should be installed by a qualified electrician within a standard electrical distribution cabinet. The light sensor must be positioned in an area where it can accurately detect natural ambient light without being obstructed or influenced by the light it is intended to control. Once installed, the sensitivity threshold can be adjusted according to the specific requirements of the location to ensure the lights activate at the desired level of darkness.

What to consider before purchase

• Ensure the total load of your lighting system does not exceed the 16A capacity.
• Verify that the installation location allows for proper sensor placement away from artificial light sources.
• Check compatibility with your existing DIN rail distribution board.

Usage recommendations

For optimal performance, ensure the external light sensor is kept clean and free from debris, and verify that it is not placed in a position where it will be triggered by the light output of the lamps it controls.
