#172422 - five volts controlling a hundred Responding to: ???'s previous message |
The circuit is powered with a 12 VDC regulated supply and the triacs switch a little over 200 VAC at 400Hz to light some EL pieces. The EL inverter is powered by the 12 VDC source, the MCU is powered via a 5V regulator. MT1 of the triac connects to logic (and 12 V) ground and MT2 of the triac is connected to the EL piece. The gate of the triac is connected through a 620 Ohm resistor to the port pin of the MCU.
I would hate to waste the customer's time building a prototype to test this out and end up blowing a couple of MCU chips when I was hoping someone here had already tried it and can give me a thumbs up or down. |
