2 Channel AC Triac Switch, Logic 3.3V/5V, AC/DC, 5A

Description

What it is

The 2-channel AC triac switch is an electronic device that allows controlling the flow of current in an AC (alternating current) circuit. Using a low-voltage control signal (3.3V or 5V), it can turn on or off the current flow in an AC circuit with a maximum of 5 Amps.

Features

• 2 control channels
• Control logic: 3.3V / 5V
• Maximum current: 5A
• Control voltage: AC/DC

What it is for

This switch is ideal for controlling electrical devices in applications with Arduino or other microcontrollers. It can be used to create home control systems, lighting systems, electric motors, and much more. It allows protecting circuits from overcurrent and electrical faults.
