Unlimited Switching: Designed for high durability with unlimited switching cycles.
Operating Temperature: Functions reliably in temperatures ranging from -40℃ to 85℃.

3. Setup and Wiring

Proper wiring is essential for the safe and correct operation of the module. Refer to the diagram below for connection details.

Wiring diagram for Youmile MOS FET Trigger Switch Drive Module showing input signal, GND, load, and DC power supply connections. — **Figure 3.1:** Wiring Diagram. This image illustrates the connection points for the input signal (PWM+), ground (GND), load (OUT+ and OUT-), and DC power supply (DC+ and DC-). The module features two MOS transistors for driving the load and an LED for switching indication.

3.1. Connection Points

VIN+ / DC+: Positive terminal for the main DC power supply (5V - 36V).
VIN- / DC-: Negative terminal for the main DC power supply.
OUT+ / LOAD+: Positive terminal for the load (e.g., motor, LED strip).
OUT- / LOAD-: Negative terminal for the load.
TRIG / PWM: Input for the trigger signal (DC 3.3V - 20V), including PWM signals.
GND: Ground connection for the trigger signal.

3.2. Wiring Procedure

Ensure all power sources are disconnected before wiring.
Connect the main DC power supply (5V-36V) to the VIN+ and VIN- terminals. Observe polarity.
Connect your load (e.g., motor, LED) to the OUT+ and OUT- terminals. Ensure the load's operating voltage is within the module's output range.
Connect your control signal source (e.g., microcontroller, PLC) to the TRIG / PWM terminal.
Connect the ground of your control signal source to the GND terminal on the module.
Double-check all connections for correct polarity and secure fastening.

4. Operating Instructions

The module operates by switching the connected load based on the input trigger signal. For applications requiring variable control, a PWM signal can be used.

4.1. Basic On/Off Control

To simply turn the load on or off, apply a digital high (3.3V - 20V) signal to the TRIG / PWM terminal for 'ON' and a digital low (0V) or disconnect for 'OFF'. The onboard LED will indicate the switching status.

4.2. PWM Control

For applications like motor speed control or LED brightness adjustment, apply a PWM signal to the TRIG / PWM terminal. The module will modulate the power to the load according to the duty cycle of the PWM signal. The supported PWM frequency range is 0-20 kHz.

6. Maintenance

The Youmile MOS FET Trigger Switch Drive 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 cloth for cleaning.
Environmental Conditions: Operate the module within the specified temperature range (-40℃ to 85℃) and avoid environments with excessive humidity or corrosive gases.
Cooling: If operating near the maximum current (above 15A), ensure adequate auxiliary cooling (e.g., heatsink, fan) is provided to prevent overheating and maintain performance.
Connection Integrity: Periodically check all wiring connections to ensure they are secure and free from corrosion.

7. Troubleshooting

If you encounter issues with the module, refer to the following troubleshooting steps:

Problem	Possible Cause	Solution
Load does not turn ON	Incorrect power supply voltage or polarity. No trigger signal or incorrect trigger voltage. Load is faulty or incorrectly wired. Module is damaged.	Verify DC power supply (5V-36V) and polarity. Check trigger signal (3.3V-20V for ON) and GND connection. Test the load independently. Recheck load wiring. Replace the module if all other checks fail.
Load does not turn OFF	Trigger signal remains high. Module is damaged.	Ensure trigger signal goes low (0V) when OFF is desired. Replace the module if the trigger signal is confirmed low.
PWM control is erratic or not working	PWM signal frequency is outside 0-20 kHz. PWM signal voltage is incorrect. Poor connection for PWM signal.	Verify PWM frequency is within the supported range. Ensure PWM signal voltage is between 3.3V and 20V. Check the integrity of the TRIG / PWM and GND connections.
Module overheats	Load current exceeds 15A without auxiliary cooling. Short circuit in the load or wiring.	Reduce load current or implement auxiliary cooling (heatsink/fan) for currents above 15A. Inspect load and wiring for any short circuits.

8. Safety Information

Please observe the following safety precautions when working with the module:

Always disconnect power before making or changing any connections.
Ensure correct polarity for all power and signal connections. Incorrect polarity can damage the module and connected devices.
Do not exceed the maximum specified operating voltage (36V DC) or current (15A continuous, 30A with cooling).
Avoid touching the module components when power is applied, especially during high-power operation, as components may become hot.
Keep the module away from water, flammable materials, and extreme temperatures.
If you are unsure about any wiring or operation, consult a qualified professional.
