Smart home light controller Synergy21 S21-LED-SR000046 wired, white, DC 12–36 V, IP20

Synergy21 S21-LED-SR000046 is a wired smart home light controller in a white housing designed for DC-powered LED lighting systems. The unit accepts a DC input voltage range of 12–36 V and provides reliable control for lighting circuits in residential automation setups. With an IP20 protection rating and a compact form factor, this controller is intended for installation in protected indoor enclosures where a stable wired controller is required to manage LED loads.

Advantages

The Synergy21 S21-LED-SR000046 offers precise wired control of DC LED circuits while maintaining a simple installation footprint and predictable behaviour. Its wide input voltage range (12–36 V DC) supports a variety of LED power supplies and LED strips, and the IP20 rating makes it suitable for indoor electrical cabinets and distribution boxes. The device’s design focuses on stable operation with LED loads, facilitating integration into existing smart home systems that require a dedicated wired controller for lighting zones.

Suitable for

• Wired smart home lighting zones using DC-powered LED strips or fixtures
• Indoor installations inside electrical cabinets, junction boxes, or under-cabinet enclosures
• Integration with home automation systems that require a dedicated wired LED controller
• Retrofit projects where a reliable DC controller is needed for brightness control and switching

Key specifications

• Input voltage: DC 12–36 V
• Protection rating: IP20 (indoor use, protected locations)
• Colour / housing: white
• Application: wired control of DC LED lighting circuits
• Weight: approximately 200 g

How to use

Mount the controller in an appropriate indoor enclosure or electrical cabinet and follow local wiring regulations when connecting power and load conductors. Ensure the DC supply falls within the specified 12–36 V range before connecting LED fixtures. Wire the LED outputs to the controller’s load terminals, verify polarity for DC connections, and integrate the controller into the home automation system according to the system’s wiring and commissioning procedures. Perform functional tests to confirm switching and dimming (if applicable) operate smoothly across the intended brightness range.

Usage recommendations

Use a stable, regulated DC power supply sized to the combined load of the connected LED fixtures and observe conductor sizing and short-circuit protection per local electrical codes. Install the unit in a location protected from moisture and excessive dust consistent with its IP20 rating, and verify compatibility between connected LED modules and the controller for reliable dimming and switching behavior.
