Adopting RF technology, it can penetrate walls, floors, and doors, allowing you to control the receiver from anywhere within a reliable range. The maximum range can reach 328 feet without obstacles. The learning code provides high security due to the low repetition rate and relearning mode, enabling you to erase the old code and learn a new one if a remote is lost. High-power load: The receiver uses a 40A relay, capable of charging high-power electrical devices to ensure long-term stable control. Wide application: It is mainly used in lamps, electric doors, windows, gates, industrial control, security, and other fields. NOTE: This is not a potentially free contact that only activates the supply voltage. Please select the appropriate remote control switch according to your device's voltage.
