6. Setup and Wiring
The module features clearly labeled terminals for power input, load output, and trigger signal input. Refer to the diagram below for proper connections.
Figure 6.1: Module Pinout and Connection Diagram. This image illustrates the various connection points on the MOSFET module, including the power supply input (DC+ / DC-), high power load output (OUT+ / OUT-), signal input range (PWM+ / GND), and the MOS tube ON indicator LED.
6.1. Connection Terminals
- DC+ / DC-: Power supply input for the load (DC 5V-36V). Connect the positive terminal of your power supply to DC+ and the negative to DC-.
- OUT+ / OUT-: Output terminals for the high-power load. Connect the positive terminal of your load to OUT+ and the negative to OUT-.
- TRIG / PWM: Trigger signal input. Connect your control signal (e.g., from a microcontroller, PLC, or DC source) to TRIG.
- GND: Ground connection for the trigger signal. Connect the ground of your control source to GND.
- LED: Indicator LED that illuminates when the MOSFET is active (ON).
6.2. Example Wiring with Arduino for Motor Control
This example demonstrates how to connect the MOSFET module to an Arduino for controlling a DC motor using PWM.
Figure 6.2: Arduino and MOSFET Module Wiring Diagram. This diagram shows an Arduino board connected to the MOSFET module. The Arduino's PWM output (e.g., Pin 9) is connected to the TRIG/PWM input of the module, and the Arduino's GND is connected to the module's GND. A separate DC power supply (5-36V) is connected to the module's DC+ and DC- terminals, and a DC motor is connected to the module's OUT+ and OUT- terminals.
Figure 6.3: MOSFET Module in a Breadboard Setup. This image displays a practical setup with the MOSFET module integrated into a breadboard circuit, controlling a small DC motor. An external power supply and a control board (possibly an Arduino or similar) are also visible, demonstrating a real-world application.
- Connect the GND pin of your Arduino (or other control device) to the GND terminal on the MOSFET module.
- Connect a PWM output pin from your Arduino (e.g., Digital Pin 9) to the TRIG/PWM terminal on the MOSFET module.
- Connect your external DC power supply (5V-36V) to the DC+ and DC- terminals on the MOSFET module. Ensure correct polarity.
- Connect your DC motor (or other high-power load) to the OUT+ and OUT- terminals on the MOSFET module. Ensure correct polarity for the motor if applicable.
- Double-check all connections before applying power.
7. Operating Instructions
Once the module is wired correctly, you can control the connected load by sending a trigger signal to the TRIG/PWM input.
- On/Off Control: Apply a high-level signal (3.3V-20V DC) to the TRIG/PWM input to turn the load ON. Apply a low-level signal (0V) or disconnect the trigger to turn the load OFF.
- PWM Control (Speed/Brightness): To control the speed of a DC motor or the brightness of an LED strip, apply a Pulse Width Modulation (PWM) signal to the TRIG/PWM input. Varying the duty cycle of the PWM signal will adjust the average power delivered to the load. The module supports PWM frequencies from 0-20KHz.
- The onboard LED indicator will illuminate when the MOSFET is switched ON, providing visual feedback of the module's state.
8. Applications
This versatile MOSFET module can be used in a wide range of applications, including:
- DC Motor speed control
- LED strip dimming and control
- Control of high-power light bulbs
- Switching micro pumps
- Actuating solenoid valves
- General high-current DC load switching
9. Troubleshooting
- Module not turning ON/OFF:
- Check all wiring connections for proper polarity and secure contact.
- Verify that the trigger signal voltage is within the specified range (3.3V-20V for high, 0V for low).
- Ensure the power supply to the module (DC 5V-36V) is active and within range.
- Test the load independently to confirm it is functional.
- Module overheating:
- The load current may be exceeding 15A. Consider adding a heatsink or active cooling (fan) if operating above 15A or in high ambient temperatures.
- Ensure the load is not short-circuited.
- PWM control not working as expected:
- Verify the PWM signal frequency is within the 0-20KHz range.
- Check the duty cycle of your PWM signal.
- No power to load:
- Confirm the main power supply (DC 5V-36V) is connected and providing power.
- Check the connections to the load (OUT+ / OUT-).
10. Maintenance
The ICQUANZX Dual MOSFET High Power Trigger Switch Module is designed for reliable operation with minimal maintenance. Follow these guidelines:
- Keep Clean: Ensure the module is free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning.
- Environmental Conditions: Operate the module within the specified temperature range (-40°C to 85°C) and avoid excessively humid environments.
- Connections: Periodically check all screw terminal connections to ensure they remain tight and secure, especially in environments with vibration.
- Cooling: For applications drawing currents close to or above 15A, ensure adequate ventilation or consider adding a heatsink to the MOSFETs to prevent thermal stress.
