Tdl2025usb Black controller A compact industrial controller and power interface for LED lighting systems. Designed for DC 5V to 24V operation and commonly used with 12V LED light bars, this unit combines a PIR human body infrared motion sensor with a photosensitive ambient light sensor and a DC connector for straightforward integration. Key benefits Automatic hands lighting: motion detection turns lights on only when people are present, reducing manual switching. Ambient light awareness: photosensitive sensor prevents activation in bright conditions, avoiding unnecessary operation. Wide voltage compatibility: supports DC 5V to 24V systems and is suitable for typical 12V LED light bars and strips. Simple integration: DC connector and compact form factor make it easy to add to existing LED installations. Industrial grade design: built for stable performance in commercial and residential lighting control applications. Main features Model: Tdl2025usb Black controller Voltage range: DC 5V to 24V; commonly paired with 12V LED systems Sensors: PIR human body infrared motion detector and photosensitive ambient light sensor Function: motion triggered switching and light sensitive automatic control for LED light bars Connection: DC connector for power and load connection Application focus: LED lighting control for indoor and semienclosed spaces Compatibility and performance Compatible with 12V LED light bars and LED strip installations running on DC 5V to 24V Designed to provide responsive on off switching based on occupancy and ambient light conditions Suited for retrofit and installations where automated lighting control is required Practical use scenarios Hallways and stairways: activate corridor lighting only when motion is detected and ambient light is low, improving convenience and reducing runtime. Under cabinet and closet lighting: automatic on off control for task lighting when a person approaches, with daylight suppression to prevent unnecessary activation. Retail displays and workbenches: motion and light sensitive switching for display illumination or task areas, ensuring lights operate when needed and stay off in bright conditions. Notes for installation Requires a DC power source within 5V to 24V range; typically used with 12V LED configurations Connect using the DC connector and place the sensor to face the monitored area for reliable motion detection Avoid exposing the sensor directly to bright light sources that can affect photosensitive performance This controller provides a practical combination of motion detection and photosensitive switching for LED lighting systems, enabling automated, context aware control with straightforward installation.
