⚡ Quick Start Guide & Important Tips

🔹 What It Does & What You Need
✅ This module does:

Controls high-power DC devices (motors, LED strips, solenoid valves, pumps)

Supports PWM speed/dimming control (0-20kHz)

15A continuous output (30A with heatsink)

Operating voltage DC 5V-36V, signal voltage DC 3.3V-20V
❌ This module does NOT: Control AC devices, support high-frequency switching >20kHz, include heatsink
🔧 You will need: Control signal source (Arduino/PLC/DC power), load device, DC power supply (5-36V)
📦 Package includes: MOSFET Trigger Switch Module × (as per SKU quantity)

🔹 Wiring & Usage in 3 Steps

⚠️ Critical Warnings:

Isolated Power: Control side (VCC/GND) and load side (VIN+/VIN-) are isolated. They require separate power supplies.

Current Limit: 15A continuous at room temperature, 30A peak. Add heatsink for high-current applications.

PWM Frequency: Supports 0-20kHz. Higher frequencies increase switching losses and heat.

Polarity: Reverse polarity on load side may damage module. Control side polarity correct is sufficient.

Inductive Loads: For motors, solenoids, add a flyback diode (e.g., 1N4007) across the load to prevent back-EMF damage.

🔹 Common Questions

❓ Why is the module getting hot?
Heat is normal under high current. Solutions: 1) Add heatsink; 2) Ensure ventilation; 3) Reduce load current; 4) Keep PWM frequency below 20kHz.

❓ Do control side and load side need common ground?
No. The module has opto-isolation – control and load sides are electrically isolated. Control signal only needs VCC/GND loop.

❓ Can I drive this directly with Arduino?
Yes. Arduino's 5V output can directly drive the IN pin. Connect VCC to Arduino 5V, GND to Arduino GND.

❓ Can it control AC devices?
No. This module is for DC loads only. For AC control, use solid-state relays or AC contactors.

❓ What if PWM frequency is too high?
Switching losses increase with frequency. Above 20kHz, heat increases significantly. Recommended: 1-10kHz.
