1. Operating voltage: AC/DC 12V - 36V (Both alternating current and direct current are acceptable. The wide operating voltage ranges from 12V to 36V (12V, 14V, 16V, 18V, 24V, 28V, 36V)). 2. Operating current: 48mA; Current: 16mA. 3. Maximum load: 10A relay (It is better that the load is less than 5A (60W)). 4. Color: White. 5. Material: ABS. 6. Functions: - The receiver can be controlled by a manual button and an external wire button (without a transmitter). - Connect the normally - open wire to the external button pins (U - S - D - GND) to make the motor cycle back. - Initial state: OFF (If there is a sudden power cut and then power resumes, the state remains off and needs to be manually turned on). - State: Instantaneous switching and locking, adjusted by the receiver jumper. (The default we send is locking. If you need to use the instantaneous mode, change the receiver jumper. Note that do not use the switching). - When the “Up” button is pressed, the motor rotates forward and stops when released. When the “Down” button is pressed, the motor rotates backward and stops when released. In the self - locking mode, when the “Up” button is pressed, the motor rotates forward and stops when the “Stop” button is pressed. When the “Down” button is pressed, the motor rotates backward and stops when the “Stop” button is pressed. - If there is no need to connect the limit switch, use a wire to connect UP, Down and COM. We have already connected it before shipment. If you need it, you can take it out. - When the output state of the receiver is “self - locking”, we have set a 0.5 - second delay time for forward and reverse rotation, which is a protection function. 7. Package contents: - 1 x Wireless remote - control controller (excluding 2 CR2016 button batteries). - 1 x Receiver controller. Only the above items are included in the package, and no other products are included. 8.
