DC 5V-36V 15A 400W Switch Large Power MOSFET Module

DC 5V-36V 15A 400W Switch Large Power MOSFET Module provides a robust and high-speed solution for controlling high-power DC devices with minimal signal effort. This module utilizes dual-parallel active output MOSFETs to deliver lower internal resistance and higher current capacity, effectively handling up to 15A at room temperature. Consequently, it replaces traditional mechanical relays in applications that require rapid switching or PWM (Pulse Width Modulation) control without the risk of contact wear. Furthermore, the trigger signal supports a wide range of logic levels, making it compatible with PLC interfaces, microcontrollers, and digital circuits. Therefore, you can achieve precise speed or brightness control in demanding industrial and hobbyist projects while maintaining high thermal efficiency.

Key Features:

• Dual MOSFET Parallel Output: The board features two imported large-power MOSFETs in parallel, which ensures lower impedance and significantly increases the power output.
• High-Speed Switching: Unlike mechanical relays, this solid-state module supports high-frequency PWM signals up to 20 kHz for smooth control of motors and lamps.
• Wide Voltage Range: The module operates on a broad DC supply range from 5 V up to 36 V, providing versatility for various power systems.
• High Current Handling: It supports a continuous current of 15 A (up to 400 W), though adding an external heatsink can boost the limit to 30 A under specific conditions.
• Long Service Life: The absence of moving parts eliminates mechanical fatigue. Consequently, the module offers nearly unlimited switching cycles compared to electromechanical switches.
