The EWD22S series LoRa remote control switch products include EWD22S-D02XR, EWD22S-A01TR series LoRa long-distance remote control switch products and the supporting EWD22S-YK02S series interactive feedback remote control products. EWD22S series, utilizes LoRa spread spectrum technology, operating in the 410-493MHz frequency band with built-in frequency hopping, ensuring long transmission distance, strong anti-interference capabilities, and high control reliability. It features a wide AC input voltage range of 85-265V and an AC 220V output. The EWD22S-D02XR utilizes a brand-name 10A relay, enabling a maximum load power of 1kW; the EWD22S-A01TR utilizes a brand-name 30A relay, enabling a maximum load power of 5kW. Its power isolation design provides high protection for safer operation.

key features of EWD22S series LoRa remote control switch

Pairing and Control

The EWD22S series can be conveniently paired with the supporting EWD22S-YK02A remote control, achieving a reliable control distance of thousands of meters, suitable for various application scenarios such as agricultural irrigation, outdoor lighting, and electrical control. When controlling the switch via the handheld remote control, the indicator light on the remote control will feedback the control result in real-time, allowing users to have a clear view of the device status.

Wall-penetrating Remote Control and Anti-interference

This remote control switch has strong wall-penetrating remote control capability with strong penetration, enabling long-distance wireless control even in environments with obstacles. It adopts LoRa modulation technology and unique frequency hopping technology, which can effectively avoid signal interference and ensure high-reliability transmission of control signals. In addition, products of the same model or different models will not interfere with each other, so users can use them with confidence.

Safety Design

It adopts a power isolation design, which not only ensures the electrical safety of the equipment but also improves the reliability of the power supply system. Its zero-crossing detection function can effectively ensure the safe operation of the power supply system and reduce potential safety hazards. In addition, the product also has a power-on self-extinguishing function. When the power grid is cut off and then restored, the switch will automatically be in the off state to avoid energy waste caused by the device restarting (users can set the memory function by themselves as needed).

Multi-to-one Control and Status Indication

The EWD22S series supports pairing with multiple remote controls (each remote control needs to be paired one by one), meeting users' diverse control needs in different scenarios. The remote control switch is equipped with a status indicator light, which turns red when it is on and goes out when it is off, allowing users to intuitively understand the working status of the device. At the same time, the product also has a manual control function. Users only need to press the <Switch/Code Pairing> button to turn on or off the device (default is self-locking mode).
