1: FET module, the input and output are completely isolated. 2: Signal trigger terminal: digital high and low level. It can be connected to the IO port of the microcontroller, PLC interface, DC power supply, etc. 3: Input signal voltage: 3V~20V; current: about 5ma. 4: The output terminal can control high-power equipment, motors, light bulbs, LED strips, DC motors, Mini water pumps, solenoid valves, etc. 5: Output controlled voltage: 5V~36V. Current: less than 5A, more than 5A need to add heat sink, the maximum can not exceed 20A. advantages of this product: 1. Realize the high frequency, fast and frequent on-off of the circuit. 2. The on-off process will not produce noise. 3. No . 4. There will be no electromagnetic interference. 5. The service life is longer than that of common electromagnetic relays. Often used to control motors, light bulbs, LED strips, DC motors, Mini water pumps, solenoid valves, etc. Using the F5305S power field effect tube, you can input PWM to control the motor speed, the brightness of the lamp, etc. Colour:As shown Material:PCB Package Contents: 1 x control board Only the above package content, other products are not included.
