Specifications

Product Description

This high-power MOS trigger module uses a high-quality MOSFET as the switching element. Input 5-18V DC, controlled by PWM signal (3.3V/5V). Continuous load current up to 40A, peak 160A (requires proper heatsinking and wiring). Ideal for DC motor speed regulation, LED strip dimming, and high-power DC electronic switches.

⚡ Quick Start Guide & Important Tips

🔹 Terminal Connections (typical)

🔹 Wiring Example

1.Connect DC power (5-18V) to VCC and GND.

2.Connect DC load (e.g., LED strip, motor) to LOAD+ and LOAD-.

3.Connect PWM signal source (e.g., Arduino PWM pin) to PWM+ and signal ground to PWM- (common ground with power).

🔹 Sample Code (Arduino)

int pwmPin = 9; // Connect to PWM+ (module GND to Arduino GND)

void setup() {
pinMode(pwmPin, OUTPUT);
}

void loop() {
for (int duty = 0; duty <= 255; duty++) {
analogWrite(pwmPin, duty);
delay(10);
}
for (int duty = 255; duty >= 0; duty--) {
analogWrite(pwmPin, duty);
delay(10);
}
}

⚠️ Critical Warnings

Current limit: Continuous ≤40A, peak 160A (<1 sec). Exceeding may damage MOSFET.

Heatsink required for currents >10A. At 40A, active cooling (fan) is necessary.

Wire gauge: Use thick wires (≥10 AWG) for high current.

Input voltage do not exceed 18V.

Inductive loads (motors, solenoids) require a flyback diode across the load; otherwise, back EMF may destroy the MOSFET.

Common ground: Signal ground must connect to power ground.

PWM frequency recommended 1-10kHz. Higher frequencies cause more heating.

🔹 Common Questions

❓ Module gets very hot?

Reduce load current, add heatsink/fan. Check PWM frequency (reduce to 1kHz). Ensure load is not shorted.

❓ Output doesn't turn fully off?

Verify control signal is LOW (0V). Some MCU pins default HIGH – add a pull-down resistor.

❓ Can I control AC load?

No, this module is for DC loads only.
