## Long description

Synergy21 S21-LED-SR000041 is a compact smart home receiver operating at 868.3 MHz, designed for low-voltage LED bulb control in wireless automation systems. The white module accepts a 12–36 V input range, supports a maximum connected load of 12.6 W and draws up to 1.4 A, allowing integration of single-channel LED luminaires into battery-backed or low-voltage installations. It is intended for discrete on/off and dimming control of compatible LED bulbs and small fixtures where space is limited and simple wireless control is required.
Advantages
The receiver’s small footprint and standard 868.3 MHz radio make it suitable for retrofit and new installations where compactness and wireless interoperability are priorities. Its wide input voltage range (12–36 V) accommodates various low-voltage supplies and LED drivers, while the rated load and current limits provide clear integration boundaries for safe operation. The white housing simplifies concealment behind fixtures or within enclosures and supports straightforward wiring for single-channel LED control.
Suitable for
Single-channel low-voltage LED luminaires and bulbs
Wireless smart home lighting control and automation scenes
Battery-backed lighting or DC-powered installations (12–36 V)
Small fixtures and retrofit installations with limited space

How to use
Mount the Synergy21 S21-LED-SR000041 inside a suitable fixture enclosure or distribution box with adequate ventilation and secure wiring. Connect the DC power supply (12–36 V) to the module’s input terminals and connect the LED load to the output, ensuring the combined wattage and current do not exceed 12.6 W and 1.4 A respectively. Pair the receiver with the compatible smart home gateway or remote control operating at 868.3 MHz following the system’s pairing procedure. After commissioning, test switching and dimming functions at low brightness to confirm correct wiring and radio communication before final installation.
Usage recommendations
Use power supplies and wiring rated for the installation environment and sized to keep voltage drop within acceptable limits for low-voltage LED operation. Do not exceed the specified 12.6 W / 1.4 A limits; for larger loads, distribute channels across multiple receivers or use a higher-capacity device. Place the receiver away from sources of heat and moisture and, if installed outdoors or in damp locations, enclose it in a certified weatherproof enclosure. Consult lamp and driver specifications to ensure compatibility with dimming and DC supply behavior.
