💻 Product Overview

This thyristor AC switch module lets a low-power control signal drive high-power AC devices. It accepts 3.3V or 5V logic from a micro-controller or a mechanical switch, and an optoisolator separates the control side from the AC side to protect the micro-controller. It is aimed at anyone building switching projects who needs to control mains-powered equipment from low-voltage electronics.

✨ Key Features

Low on-resistance: The module uses a thyristor with very low on-resistance for switching.
Wide logic compatibility: Works with 3.3V or 5V micro-controllers and mechanical switches.
Optoisolation: An optoisolator protects the micro-controller from high AC currents.
Low-power control: High-power devices can be driven from a low-power control mechanism.
AC and DC logic: The control side is specified for 3.3V/5V logic AC/DC.
