100A High Power MOS Trigger Switch Module

Description

The 100A High Power MOS Trigger Switch Module is a robust, low-resistance MOSFET switching module designed for high-current DC applications. Engineered with precision and efficiency in mind, this trigger switch enables seamless on/off control of heavy DC loads such as motors, LEDs, solenoids, inverters, and battery systems, using logic-level triggers from microcontrollers like Arduino, ESP32, Raspberry Pi, or PLCs.

With a working voltage range of 5V to 26V DC and a maximum output current of 100A, this MOSFET switch module is ideal for power-hungry circuits where mechanical relays are either too slow or unreliable. The onboard N-channel MOSFETs are optimized for ultra-low on-resistance, ensuring minimal heat generation and superior energy efficiency.

This module features an optically isolated trigger input, protecting your control logic from voltage spikes and electrical noise. The trigger can be activated with as little as 3.3V–12V, making it compatible with both 3.3V and 5V systems. Whether you’re building an automated battery management system, solar inverter, DIY electric vehicle, or industrial power switch, this module offers reliable and noise-free switching for your high-current DC loads.
