Intelligent AC Power Bar

摘要

This circuit is a modified version of the circuit found at MI. The purpose of the circuit is to ensure that AC power is not supplied to devices connected to K3 unless the device connected to K2 is drawing sufficient power.rnSix power diodes connected in series with the load plugged into to K2 generate a voltage drop of approximately 2 V if the load is switched on. This voltage drives a triac, which in turn supplies power to the load plugged into K3.
