The THC 109 is a modular light-sensing relay compatible with AC220V/50-60Hz voltage, supporting 16A/20A/25A resistive loads. Its core advantage is automatically switching loads on/off based on ambient light (only working at night), and it is not affected by temperature or humidity. Equipped with an external photocell probe, it is flexible to install, suitable for outdoor lighting scenarios like street lights and garden lights, with both convenience and stability.
Core matched accessories and functions:
· External photocell probe: Extends the light-sensing component, installable in unobstructed lighting areas to avoid host occlusion affecting accuracy;
· Extension cable: Optional length (1-3m by default) for long-distance connection between the probe and host;
· Waterproof junction box: IP65 protection level, suitable for outdoor humid environments to protect the host circuit;
· DIN rail bracket: Standard 35mm rail clip, easy for integrated installation in distribution cabinets.
