Low-Voltage DC Microwave Sensing For 12V\/24V Lighting<\/h2>\n\n

The RZ047 12V\/24V model is the low-voltage DC version of the RZ047 ceiling microwave sensor family, intended for projects using a constant-voltage 12 VDC or 24 VDC power supply.<\/p>\n\n

It keeps the same ceiling-mounted 360-degree microwave sensing concept while separating DC lighting projects from the 100-265 VAC 5A and 10A RZ047 models.<\/p><\/div><\/div><\/div><\/div>

Low-Voltage DC Sensing For 12V\/24V Lighting Projects<\/h2>\n\n

Use this version when the lighting control design is built around compatible low-voltage DC power rather than standard AC line voltage.<\/p>\n\n

The microwave sensing behavior still requires careful placement because movement through glass, thin partitions, or nearby spaces may be detected unless sensitivity and location are adjusted for the room.<\/p><\/div><\/div><\/div><\/div>

Features, Benefits, Specs<\/h2>\n\n

The RZ047 12V\/24V model combines low-voltage DC power, 5.8 GHz microwave detection, and adjustable settings so buyers can confirm DC supply fit, placement, and control behavior.<\/p><\/div><\/div>

Features & Benefits<\/h2>\n\n
  • 12V\/24V DC input:<\/strong> Works from a constant-voltage 12 VDC or 24 VDC supply with a 10-30 VDC input range.<\/li>\n\n
  • 10A max work current:<\/strong> Supports compatible low-voltage DC loads within the 10A max work current limit.<\/li>\n\n
  • DC wiring path:<\/strong> Separates Black to DC positive, White to DC negative, Red to Load positive, and Load negative back to DC negative.<\/li>\n\n
  • 5.8 GHz microwave sensing:<\/strong> High-frequency Doppler detection actively senses movement for ceiling-mounted automatic lighting control.<\/li>\n\n
  • 360-degree ceiling coverage:<\/strong> Ceiling placement gives broad room coverage with an 8-12 m detection diameter under RZ047 family conditions.<\/li>\n\n
  • Selectable Lux threshold:<\/strong> Set Off, 15 Lux, 25 Lux, or 35 Lux so the load responds to motion only when the ambient-light condition fits the installation.<\/li>\n\n
  • High\/low sensitivity:<\/strong> The SENS button helps reduce nuisance detection through doors, glass, partitions, or adjacent spaces.<\/li><\/ul><\/div><\/div><\/div><\/div>

    FAQ<\/h2><\/div><\/div>

    Is the RZ047 12V\/24V model for AC line voltage?<\/h3><\/div><\/div>\n\n

    No. This model is for a constant-voltage DC power supply. Use the RZ047-5A or RZ047-10A models for 100-265 VAC line-voltage applications.<\/p><\/div><\/div><\/div><\/div>\n\n

    What DC voltage does it use?<\/h3><\/div><\/div>\n\n

    It uses 12 VDC \/ 24 VDC input with a 10-30 VDC input range.<\/p><\/div><\/div><\/div><\/div>\n\n

    How is the DC model wired?<\/h3><\/div><\/div>\n\n

    Black connects to 12V\/24VDC positive, White connects to 12V\/24VDC negative, Red connects to Load positive, and Load negative returns to 12V\/24VDC negative.<\/p><\/div><\/div><\/div><\/div>\n\n

    What is the max work current?<\/h3><\/div><\/div>\n\n

    The low-voltage DC model uses a 10A max work current. Confirm the load and power supply before installation.<\/p><\/div><\/div><\/div><\/div>\n\n

    Does it use the same microwave sensing concept as the AC models?<\/h3><\/div><\/div>\n\n

    Yes. It is positioned as the low-voltage DC version of the RZ047 ceiling microwave sensor family, with the same 5.8 GHz microwave sensing concept and adjustable settings.<\/p><\/div><\/div><\/div><\/div>\n\n

    Can microwave sensing detect outside the intended area?<\/h3><\/div><\/div>\n\n

    Yes. Microwave sensing can detect through many non-metal materials, so reduce sensitivity or relocate the sensor if doors, glass, partitions, or adjacent spaces cause nuisance triggering.<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
