Low-Voltage DC Microwave Sensing For 12V/24V Lighting
The RZ048 12V/24V model is the low-voltage DC version of the recessed RZ048 ceiling microwave sensor family, intended for projects using a constant-voltage 12 VDC or 24 VDC power supply.
It keeps the same recessed 360-degree microwave sensing concept while separating DC lighting projects from the 100-265 VAC 5A and 10A RZ048 models.
Low-Voltage DC Sensing For 12V/24V Lighting Projects
Use this version when the lighting control design is built around compatible low-voltage DC power rather than standard AC line voltage.
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.
功能、优点和规格
The RZ048 12V/24V model combines low-voltage DC power, recessed mounting, and 5.8 GHz microwave detection so buyers can confirm DC supply fit and placement.
功能与优点
- 12V/24V DC input: Works from a constant-voltage 12 VDC or 24 VDC supply with a 10-30 VDC input range.
- 10A max work current: Supports compatible low-voltage DC loads within the 10A max work current limit.
- DC wiring path: Separates Black to DC positive, White to DC negative, Red to Load positive, and Load negative back to DC negative.
- 5.8 GHz microwave sensing: High-frequency Doppler detection actively senses movement for ceiling-mounted automatic lighting control.
- Recessed ceiling form: Screw mount or spring clip mounting supports a low-profile ceiling installation with the documented 82-90 mm cutout.
- 360-degree ceiling coverage: Ceiling placement gives broad room coverage with an 8-12 m detection diameter under RZ048 family conditions.
- High/low sensitivity: The SENS button helps reduce nuisance detection through doors, glass, partitions, or adjacent spaces.

常见问题
Is the RZ048 12V/24V model for AC line voltage?
No. This model is for a constant-voltage DC power supply. Use the RZ048-5A or RZ048-10A models for 100-265 VAC line-voltage applications.
What DC voltage does it use?
It uses 12 VDC / 24 VDC input with a 10-30 VDC input range.
How is the DC model wired?
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.
What is the max work current?
The low-voltage DC model uses a 10A max work current. Confirm the load and power supply before installation.
Does it use the same microwave sensing concept as the AC models?
Yes. It is positioned as the low-voltage DC version of the RZ048 recessed ceiling microwave sensor family, with the same 5.8 GHz microwave sensing concept and adjustable settings.
Can microwave sensing detect outside the intended area?
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.
