⚡ Quick Start Guide & Important Tips

🔹 What It Does & What You Need

✅ This module does: Acts as a high-power electronic switch – controls DC loads (5V-36V) via high/low or PWM signals for on/off, speed control, dimming
❌ This module is NOT: A voltage regulator (output voltage = input voltage), nor isolated (signal and power share ground)
⚠️ Current Capacity:

• Room temp, natural cooling: 15A continuous (400W)

• With heatsink (recommended): 30A continuous (800W)

• Exceeding limits may damage the module

🔧 You will need:

• DC power supply (5V-36V, rated for your load power)

• Load device (motor, LED strip, solenoid valve, etc.)

• Control signal source (Arduino, PLC, MCU IO or PWM output)

🔹 Wiring in 4 Steps

1. Connect Power: VCC → power positive, GND → power negative

2. Connect Load: OUT+ → load positive, OUT- → load negative

3. Connect Signal: SIG → MCU/PLC signal output (IO or PWM), and share ground (signal GND connected to power GND)

4. Test: High level (or PWM) → module turns ON; low level → module turns OFF

⚠️ Critical Warnings!

Ground must be shared: Module won't work if signal ground and power ground are not connected

Polarity matters: Reversing VCC/GND will burn the module

NO 220V AC: This module is for DC loads only

🔹 Common Questions & Tips

❓ Why does my motor make noise or heat up during PWM control?

PWM frequency should be between 1KHz and 20KHz. Too low (<100Hz) may cause motor vibration or whining; too high (>20KHz) may cause incomplete switching and extra heat.

❓ What happens if load current exceeds 15A?

Short-term overload may cause overheating. For continuous 30A, a heatsink is required (recommend our Heatsink Kit) with good ventilation.

❓ Can I control AC motors or 220V devices?

No. This module is designed for DC loads only, with input/output voltage range DC 5V-36V. For AC control, use an AC solid-state relay module.

❓ Can I use 3.3V logic (like ESP32) to trigger?

Yes. The trigger signal voltage range is DC 3.3V-20V, so 3.3V logic works perfectly.

❓ Is there a voltage drop when the module is on?

Yes, a small drop exists due to MOSFET internal resistance. At 15A, the drop is about 0.1V-0.2V, generating about 2W-3W of heat – normal operation.
