Feature: 1. When the external forward switch (K1) is pressed, the motor will rotate forward. When K1 is released, the motor will stop running immediately. 2. Copper wiring terminal, strong overcurrent ability and low heat. 3. The inputs are all optocoupler coupling, which is resistant to transient interference. 4. 6V~40V input, DC voltage regulation, low power consumption, stable operation. 5. 20A relay, strong load capacity. Specification: Item Type: Motor Rotation Controller Working Voltage: Wide voltage 6.0V~40V (DC) Module Power Consumption: 0.6W (without load motor), static 0.1W Signal Input: The low level is effective and the input is the negative pole of the optocoupler. A voltage below 2V is considered a signal. Response Speed: K1 K2 is 20mS, SW1 SW2 is 50mS Output Current; 20A Operating Life: >150,000 times Package List: 1 x DC Motor Controller Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
