Vexen TWILO TWS-10AS Twilight Sensor, IP54 Surface Mounted

The Vexen TWILO TWS-10AS is a high-quality twilight sensor designed to automate lighting systems by monitoring ambient light levels. This surface-mounted photorelay ensures that your exterior or interior lights activate precisely at dusk and deactivate at dawn, providing a seamless and energy-efficient solution for residential and commercial properties. With its robust construction and IP54 rating, it is built to withstand environmental factors, ensuring reliable performance in various outdoor conditions.

Advantages

This twilight sensor offers significant energy savings by eliminating the need for manual lighting control and preventing lights from staying on during daylight hours. The device features a wide sensitivity range, allowing users to customize the activation threshold between 3 and 500 lux to suit specific environmental needs. Its surface-mounted design simplifies installation, while the high load capacity of 1800 W makes it versatile enough to handle multiple lighting fixtures simultaneously. The inclusion of adjustable time settings provides further flexibility in managing operational cycles.

Suitable for

• Automatic control of garden and pathway lighting
• Managing exterior building illumination
• Lighting systems for parking lots and driveways
• Commercial signage and storefront lighting

This sensor may not be suitable for indoor areas where artificial light sources frequently trigger the sensor, causing the lights to flicker or remain off. It is also not intended for use in environments where the ambient light levels are consistently above the 500 lux threshold or in areas requiring submersion in water, as the IP54 rating only protects against splashing water and dust.

Key specifications

• Voltage: 230 V
• Maximum load: 1800 W
• Current: 10 A
• Sensitivity threshold: 3 - 500 lux
• Protection rating: IP54
• Mounting type: Surface mounted
• Poles: 1P

To use the Vexen TWILO TWS-10AS, mount the device on a stable surface where it can accurately detect natural ambient light without being obstructed by shadows or direct artificial light. Connect the device to your lighting circuit according to the provided wiring diagram. Use the LUX knob to set the desired light sensitivity; turning it toward the 3 lux mark ensures activation only in near-total darkness, while turning it toward 500 lux allows for earlier activation. Adjust the time setting to define the duration of operation as required for your specific application.

What to consider before purchase

• Ensure the total wattage of your lighting fixtures does not exceed 1800 W.
• Verify that the mounting location is not directly exposed to the light of the lamps it controls.
• Check that the surface is suitable for a fixed installation.
• Confirm the local voltage matches the 230 V requirement.

For optimal performance, periodically clean the sensor lens to prevent dust or debris buildup, which can interfere with accurate light detection. Ensure the device is installed by a qualified professional to maintain safety and warranty compliance.
