PowerSwitch Tail II

The PowerSwitch Tail II is a great and VERY simple way to have the Arduino control AC powered devices. I’ve used these in my LCC project. The Arduino can control these directly from a digital IO port, BUT you’re better off using a transistor to drive them, just in case…

You can get them at SparkFun.

Description:

The PowerSwitch Tail II is designed to allow you to safely control an outlet device without exposing any 120VAC voltages. You can plug in any standard 120VAC 3-prong outlet to be controlled by most any microcontroller. This will work great with Arduino! The PowerSwitch Tail II improves on the original PowerSwitch Tail by allowing you to switch a bigger load (now up to 15A) with a wider range of control signals (3-12VDC).

 

Features:

  • Connect to Arduino, PIC, Stamp, or other MCU with driver transistor or ULN2803
  • LED indicator shows status of control signal
  • Connect output receptacle to a single powered device or to a power strip to control multiple loads.
  • Switches up to 15A (resistive loads) with a 3-12VDC, 3-30mA control signal.
