Zamel WZM-02/S1 Twilight Switch with SOH-01 External Probe 10A 230VAC

The Zamel WZM-02/S1 is a professional twilight switch engineered for the automated management of lighting systems based on real-time ambient light intensity. This device operates on a 230VAC power supply and features a robust 10A relay, making it suitable for a wide range of residential and commercial lighting applications. By utilizing the included SOH-01 external probe, the system accurately monitors light levels and triggers connected circuits only when natural light falls below a pre-set threshold, thereby optimizing energy consumption and enhancing convenience.

Advantages

This twilight switch offers significant benefits by ensuring that lighting is only active during hours of darkness, which effectively reduces electricity costs and extends the lifespan of light sources. The inclusion of the SOH-01 external probe allows for flexible installation, as the sensor can be positioned in an area with optimal exposure to natural light while the main control unit remains protected within an electrical cabinet or enclosure. Its high load capacity of 10A provides sufficient power for various lighting configurations, and the reliable design ensures consistent performance in changing weather conditions.

Suitable for

• Automatic control of outdoor garden and pathway lighting
• Illumination of advertising displays and billboards
• Street lighting management for residential areas
• Energy-efficient operation of building facade lighting

This device may not be suitable for indoor environments where artificial light sources could interfere with the sensor's ability to detect natural daylight accurately. It is also not intended for high-voltage industrial machinery or applications requiring complex programmable timing beyond simple light-level detection.

Key specifications

• Operating voltage: 230VAC
• Maximum load capacity: 10A
• Sensor type: External SOH-01 probe
• Function: Twilight-based automatic switching

Installation should be performed by a qualified professional in accordance with local electrical regulations. The control unit is typically mounted on a standard DIN rail within a distribution board, while the SOH-01 probe must be installed in a location shielded from direct artificial light sources, such as street lamps or security lights, to prevent false triggering. Once mounted, the sensitivity threshold can be adjusted to match the specific lighting requirements of the installation site.

What to consider before purchase

• Ensure the total power consumption of the connected lighting does not exceed the 10A relay limit
• Verify that the cable length between the probe and the control unit is appropriate for your installation layout
• Confirm that the mounting location for the probe is free from obstructions and direct artificial light

For optimal performance, regularly clean the surface of the SOH-01 probe to prevent the accumulation of dust or debris, which could affect light sensitivity. Ensure that the probe is not positioned where it will be directly illuminated by the lights it controls, as this will cause the system to cycle on and off repeatedly.
