Zamel WZN-01/S1 Twilight Switch with SOH-01 Probe 16A 230V AC

The Zamel WZN-01/S1 Twilight Switch with SOH-01 Probe is a reliable automation device engineered to manage lighting systems based on real-time ambient light intensity. By utilizing an external light-sensitive probe, the unit ensures that connected lighting circuits activate automatically at dusk and deactivate at dawn, providing a seamless solution for energy management and convenience in various environments.

Advantages

This twilight switch offers significant benefits for energy efficiency by ensuring lights are only operational when natural light is insufficient. The inclusion of the SOH-01 external probe allows for flexible installation, enabling the sensor to be placed in an optimal location for light detection while the main control unit remains in a protected enclosure. Its robust 16A contact rating makes it suitable for handling substantial lighting loads, while the 230V AC compatibility ensures integration into standard electrical installations.

Suitable for

• Automatic control of street lighting and garden illumination
• Lighting management for building facades and parking areas
• Energy-saving solutions for commercial signage and display windows
• Residential driveway and pathway lighting automation

This device may not be suitable for indoor environments where artificial light sources frequently trigger the sensor, leading to unwanted switching cycles. It is also not intended for applications requiring complex time-based scheduling or dimming functions, as it operates strictly based on ambient light thresholds.

Key specifications

• Rated voltage: 230V AC
• Maximum contact current: 16A
• Contact configuration: 1Z (normally open)
• Sensor type: External SOH-01 probe
• Operating principle: Twilight-based switching

To use the Zamel WZN-01/S1, the control unit should be mounted in a suitable electrical distribution board, while the SOH-01 probe must be installed in a location exposed to natural daylight but shielded from direct artificial light sources. Once wired according to the provided technical diagram, the sensitivity threshold can be adjusted to match the specific lighting requirements of the installation site. The device will then monitor light levels continuously and switch the connected load automatically.

What to consider before purchase

• Ensure the installation location for the probe is free from interference by artificial light
• Verify that the total load of the lighting system does not exceed the 16A rating
• Confirm compatibility with your existing electrical distribution system

For optimal performance, ensure the SOH-01 probe is protected from direct weather elements if installed outdoors and keep the sensor surface clean to prevent inaccurate light detection.
